A Spacecraft Traveling Out Of The Solar System At A Speed Of 0.94c Sends Back Information At A Rate Of (2024)

Physics High School


Answer 1

The rate at which we receive the information from a spacecraft traveling at 0.94c is the same as the rate at which it is sending the information, which is 680 Hz.

This is because the speed of light is constant, regardless of the speed of the source.

The speed of light is an important factor in determining the rate at which information is received from an object traveling at a velocity close to that of light. This is because, according to Einstein's Theory of Relativity, the speed of light is the same for all observers in all reference frames. This means that, regardless of the speed of the source, the speed at which light travels is the same.

imagine you're in a completely dark room with no windows and you cut a 1- ft2 round hole in the roof. when the sun is high in the sky, about 100 w of solar power enters the hole. on the floor where the light hits, you place a beach ball covered with aluminum foil, with the shiny side out. discuss the illumination in your room compared with that of a 100- w incandescent lightbulb?


In the given case,

The illumination in the room would be much less compared to that of a 100-w incandescent lightbulb.

The light entering the completely dark room with no windows through the 1-ft2 round hole would be diffused, meaning that it would be spread out instead of concentrated in one spot. Additionally, the light that does enter the room would be reflected off the aluminum foil and would not be as bright as a direct light source such as an incandescent bulb. Therefore, the overall amount of light entering the room would be significantly less than that of a 100-w incandescent lightbulb.

Compared to visible radiation, does infrared radiation have longer or shorter wavelengths and higher or lower energy per photon?


Infrared radiation has longer wavelengths and lower energy per photon compared to visible radiation.

The electromagnetic spectrum's visible region has wavelengths between 400 and 700 nanometers, which correspond to the hues violet, blue, green, yellow, orange, and red. As opposed to visible light, infrared light has longer wavelengths, with a range of about 700 nanometers to 1 millimetre or more.

The energy of a photon is directly proportional to its frequency, per the Planck-Einstein connection (or inversely proportional to its wavelength). As a result, infrared radiation has lower frequencies and less energy per photon than visible radiation due to its longer wavelengths.

In conclusion, infrared radiation has longer wavelengths and lower energy per photon than visible radiation.

which of the following objects has the largest momentum? (a) a bullet fired from a rifle (b) a football quarterback running at top speed (c) a horse walking at about 2 miles/hour (d) an elephant standing still


Of the four objects listed, the bullet fired from a rifle will have the largest momentum. This is because the bullet has a relatively small mass but a very high velocity, which gives it a large amount of momentum.

What is momentum?

Momentum is a physical quantity that describes the motion of an object. It is a measure of an object's resistance to changes in its velocity and is related to the mass of the object and its velocity. Momentum is a vector quantity, meaning it has both magnitude and direction, and is defined as the product of an object's mass and velocity.

Explanation & Formula:

The object with the largest momentum depends on the mass of the object and its velocity. Momentum is defined as the product of an object's mass and velocity, and is denoted by the symbol "p". Mathematically, it can be expressed as:

p = m * v


p = momentum

m = mass of the object

v = velocity of the object

Of the four objects listed, the bullet fired from a rifle will have the largest momentum. This is because the bullet has a relatively small mass but a very high velocity, which gives it a large amount of momentum. The other objects, such as the football quarterback running at top speed, the horse walking at 2 miles/hour, and the elephant standing still, will have lower velocities and therefore lower momenta.

if the cost of electrical energy is $0.075 per kilowatt-hour, how much does it cost to operate the light for an hour?


$0.075 is the cost to operate the light for an hour.

As per the given information,

The cost of electrical energy = $0.075 per kilowatt-hour

Kilowatt-hours, or kWh, are the measure of electrical energy. They are calculated by multiplying the amount of power used (measured in kW) by the number of hours during which it is used. The total cost of energy is calculated by multiplying that figure by the price per kWh.

If we assume that the light uses 1 kilowatt-hour of electrical energy every hour of use, we can compute the cost of running the light for an hour as follows:

Cost = Energy used x Cost per kilowatt-hour

Cost = 1 kilowatt-hour x $0.075 per kilowatt-hour

Cost = $0.075

Therefore, it would cost $0.075 to operate the light for one hour. If the light consumes more or less than 1 kilowatt-hour per hour, then the cost would be proportionally higher or lower.

a boater traveling at (4.50 a) m/s relative to the water, aims the bow of the boat to go straight across a river. if the river is (54.0 b) m wide and the current in the river is 3.50 m/s, how far downstream will the boat land on the other side of the river? calculate the answer in meters (m) and rounded to three significant figures.


The boat will land about 185 meters downstream on the other side of the river.

Distance = velocity × time

d = v_r × t

where v_r is the velocity of the river and t is the time it takes for the boat to cross the river.

Use the fact that the distance the boat travels in the x-direction is equal to the width of the river,

x = 54.0 b

The time it takes for the boat to cross the river is,

t = x / v_b

where v_b is the velocity of the boat relative to the water.

To find v_b, use the Pythagorean theorem:

v_b^2 = v_w^2 + v_c^2

where v_w is the velocity of the boat with respect to the ground and v_c is the velocity of the current.

v_b^2 = (4.50 a)^2 + (3.50)^2

v_b = 5.71 a

Substituting the values for x, v_b, and v_r into the equation for d,

d = (3.50 m/s) * (54.0 b) / (5.71 a)

d ≈ 185 b/a meters

What are Tides ?

When the tide is low, the Moon faces the Earth at a straight angle to the Sun, which causes the Moon and Sun's gravitational pull to be antagonistic. These tides are known as neap tides, which are low tides or tides that are lower than usual.

People frequently refer to abnormally high tides with the non-scientific term "king tide."

an object sits on a frictionless surface. a 16-n force is applied to the object, and it accelerates at 2.0 m/s2. what is the mass of the object?


The mass of the object is 8 kg.

Due to inherent inertia, an object moving over a frictionless surface will keep moving at the same speed. Since an object's inertia is reliant on its mass, as mass grows, so does the object's resistance to changing velocity. The relationship between force and acceleration is described by Newton's second law of motion. They are equivalent in size. The acceleration of an object rises by the same amount as the force being applied to it. Force is simply defined as mass times acceleration.

two blocks of unequal mass (ma < mb) are connected by a string (string 2). the blocks are placed on a frictionless table and pulled by another string (string 1) attached to block a such that both blocks move together faster and faster. assume that both strings are inextensible and massless. is the magnitude of the acceleration of block a greater than, less than, or equal to the magnitude of the acceleration of block b?


The magnitude of the acceleration of block a is actually equal to the magnitude of the acceleration of block b sice both blocks (even with different masses) are pulled by the same force, meaning same acceleration.

Force is created when an object is accelerating. When a mass is accelerating, it is changing speeds or directions. No wonder in physics, force is equal to mass times acceleration (F = ma).

When an object is at rest, there's no force acting on it, so the force would be zero. This is the same case with objects moving at a constant speed in the same direction; there is no force acting on those objects.

Since the blocks are moving in the same direction, and there's only one pulling force acting on both blocks, the magnitudes of the acceleration of both blocks have to be the same. For instance, all objects on Earth (even with different masses) experience the same acceleration of Earth's gravity.

car rounds an unbanked curve of radius 66 m. if the coefficient of static friction between the road and car is 0.66, what is the maximum speed (in m/s) at which the car can traverse the curve without slipping? m/s


The maximum speed at which the car can traverse the curve without slipping is approximately 21 m/s

The maximum speed at which a car can traverse an unbanked curve without slipping is determined by the maximum frictional force available to counteract the centripetal force acting on the car.

The centripetal force is given by the equation:

F = m * [tex]v^2[/tex] / r

where m is the mass of the car, v is its speed, and r is the radius of the curve. The frictional force is given by:

F_friction = μ * N

where μ is the coefficient of static friction and N is the normal force acting on the car, equal to its weight.

Setting the two forces equal, and substituting the expression for N, we have:

μ * m * g = m * [tex]v^2[/tex] / r

Solving for v, we get:

v = [tex]\sqrt{ }[/tex](μ * g * r)

Plugging in the given values, we get:

v = sqrt(0.66 * 9.8 * 66) = sqrt(439.48) = 20.99 m/s

a 0.140 kg baseball is dropped from rest from a height of 2.2 m above the ground. it rebounds to a height of 1.6 m. what change in the balls momentum occurs


The change in momentum of the baseball is 0.58 kg m/s

To calculate the change in momentum of the baseball, we need to find the initial and final momentum of the ball.

The initial momentum of the ball can be calculated as follows:

m = mass of the ball = 0.140 kg

v = initial velocity (at rest) = 0 m/s

p = m * v = 0.140 kg * 0 m/s = 0 kg m/s

The final momentum of the ball can be calculated after it has rebounded to a height of 1.6 m:

h = height = 1.6 m

g = acceleration due to gravity = 9.8 m/s^2

v = final velocity = √2gh = √2 * 9.8 m/s^2 * 1.6 m = 4.1 m/s

p = m * v = 0.140 kg * 4.1 m/s = 0.58 kg m/s

The change in momentum of the ball is equal to the final momentum minus the initial momentum:

Δp = p_final - p_initial = 0.58 kg m/s - 0 kg m/s = 0.58 kg m/s

So the change in momentum of the baseball is 0.58 kg m/s.

What is the next challenge facing Edison to make electrical lighting possible? ​


Finding a suitable material for the filament of an incandescent light bulb was one of Thomas Edison's biggest obstacles.

What is filament ?

The source of light in an incandescent light bulb is the filament, which is a wire-like structure. It is often constructed of tungsten or another material with a high melting point and good thermal shock resistance. When an electric current is sent through the filament, which is commonly twisted into a coil or loop shape, the filament heats up and starts to generate light.

Thermal radiation causes the filament to produce light. This is the result of the filament's temperature-related electromagnetic radiation output. The filament starts to emit infrared radiation and visible light as it warms up.

The filament's temperature and the kind of material it is constructed of affect the hue of the light it emits.

A glass bulb that has been evacuated or a bulb that has been filled with an inert gas, such as argon or nitrogen, surrounds the filament in an incandescent light bulb. By doing this, you can avoid the filament from burning out or breaking, which would make the lightbulb unusable.

5 m^3/s * 6 s = 30 m^3

To find the mass of the water that flows through the pipe, we can use the density of water:

mass = density * volume

mass = 1000 kg/m^3 * 30 m^3 = 30000 kg

So, the volume that flows through the pipe in 6 seconds is 30 cubic meters, and the mass of the water is 30000 kg.

A Spacecraft Traveling Out Of The Solar System At A Speed Of 0.94c Sends Back Information At A Rate Of (2024)


How does the momentum of an electron traveling at 0.99 C compare with its classical momentum? ›

How does the momentum of an electron traveling at 0.99c compare with its classical momentum? For v = 0.99c, y is 7.1. The momentum of the bus is more than seven times greater than would be calculated if classical mechanics were valid. The same is true of electrons, or anything traveling at this speed.

How long would it take to get out of the solar system at the speed of light? ›

A trip at light-speed to the very edge of our solar system – the farthest reaches of the Oort Cloud, a collection of dormant comets way, way out there – would take about 1.87 years. Keep going to Proxima Centauri, our nearest neighboring star, and plan on arriving in 4.25 years at light speed.

How much time would pass on Earth if I traveled at the speed of light for a year? ›

At 99.99 percent of the speed of light, a craft traveling for one year would come back to a world that had aged more than 70 years in their absence. At 99.99999 percent of the speed of light, for a year, more than 2000 years would pass on Earth.

How does the time measured in the spaceships frame of reference change as the speed of the spaceship increases? ›

How does the distance that light travels in Earth's frame of reference change as the speed of the spaceship increases? A- The time measured in the spaceship's frame of reference does not change.

What is the momentum of an electron traveling at 0.980 c? ›

Short Answer

The momentum of an electron traveling at 0.980c is approximately 1.34 × 10 − 22 kg m/s.

What is the momentum of proton moving at speed 0.92 c? ›

Expert-Verified Answer

Therefore, the momentum of the proton moving at a speed v = 0.92c is 1.378 MeV/c (option d).

How long to travel outside the solar system? ›

The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/390 of a light-year in 46 years and is currently moving at 1/17,600 the speed of light. At this rate, a journey to Proxima Centauri would take 75,000 years.

How fast can you escape the solar system? ›

The initial speed required to escape the Sun from its surface is 618 km/s (1,380,000 mph), and drops down to 42.1 km/s (94,000 mph) at Earth's distance from the Sun (1 AU), and 4.21 km/s (9,400 mph) at a distance of 100 AU.

How far is it to get out of the solar system? ›

Explanation: The edge of our solar system is where our suns gravity stops being the greatest gravity affecting us. This boundry is about 100 000AU (astronomical unit) or about 9 300 000 000 000 miles.

How much is 1% light speed? ›

While 1% of anything doesn't sound like much, with light, that's still really fast – close to 7 million miles per hour! At 1% the speed of light, it would take a little over a second to get from Los Angeles to New York. This is more than 10,000 times faster than a commercial jet.

Do you age if you travel at the speed of light? ›

If you moved very very fast, very close to the speed of light, very little time would pass for you. If you moved fast enough, you would only age a day.

How long is 1 second in light speed? ›

The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c," or light speed.

Does time slow down the faster you go? ›

As light is spread out by the observer moving away from the source of the light time is decreased. The faster the observer moves the more light is spread out and time slows down. Phillip E. Time slows down as you travel faster because momentum bends the fabric of spacetime causing time to pass slower.

Does time stop at the speed of light? ›

Time can be stopped for a person if he/she travels at a speed of light as per the special theory of relativity. Clocks in a moving frame of reference tick more slowly than an observer's “stationary” clock.

How do spaceships know their speed? ›

If a spacecraft can determine it's position more than once in real time, then it knows how fast it is going simply by comparing the distance traveled between the positions. Primarily, there is radar. A spacecraft points its own radar at its destination and measures the distance to the destination. Simple.

What is momentum How do you compare momenta of different objects? ›

Momentum is directly proportional to the object's mass and also its velocity. Thus the greater an object's mass or the greater its velocity, the greater its momentum. Momentum p is a vector having the same direction as the velocity v. The SI unit for momentum is kg · m/s.

How does the momentum of a photon compare to the momentum of an electron of identical energy? ›

The momentum p of a particle is inversely proportional to its de Broglie wavelength λ, given by p = h/λ, where h is Planck's constant. Since the photon and electron have the same wavelength, they have the same momentum. For energy, the total energy E of a photon is given by E = pc, where c is the speed of light.

Is relativistic momentum greater than classical momentum? ›

At low velocities, relativistic momentum is equivalent to classical momentum. Relativistic momentum approaches infinity as u approaches c . This implies that an object with mass cannot reach the speed of light. Relativistic momentum is conserved, just as classical momentum is conserved.
