When in orbit, a satellite such as the space shuttle isa. simply a projectile.
b. in non-accelerated motion.
c. free from Earth's gravity.

Answers

Answer 1
Answer:

Answer: B

Explanation:

When in orbit, a satellite is hold in position thanks to, between others, the earth's gravity. So the C option is discarded.

A projectile is an object thrown by the exertion of some force, like a bullet or a cannonball.

A satellite is placed in some orbit, so he can rotate the earth. The movement of the satellite is non-accelerated motion, because the only forces that act on the satellite are the forces that hold him in orbit.
Answer 2
Answer:

Final answer:

When in orbit, a satellite such as the space shuttle is in non-accelerated motion and is influenced by Earth's gravity.

Explanation:

When in orbit, a satellite such as the space shuttle is in non-accelerated motion.

It is not simply a projectile because it is continuously under the influence of Earth's gravity.

However, it is not completely free from Earth's gravity as it continues to be pulled towards the Earth.

What happens to light when it enters a lens? A. It speeds up.

B. It is reflected.

C. It is refracted.

D. It becomes brighter.

Answers

Good Morning! When the light passes through a lens - whether of increase or withdrawal - it tends to be refracted, that is, to suffer a deviation in its trajectory. Depending on the type of lens, it may be that some of the light is reflected too, but this is not the common parameter. Correct letter is therefore c). Hugs!Hope this helps. Let me know if you need additional help!

Answer: i think the answer is c hope this helps

A car that travels from point A to point B in four hours, and then from point B back to point A in six hours. The road between point A and point B is perfectly straight, and the distance between the two points is 240 km. What is the car’s average velocity?

Answers

Note : Be careful with speed and velocity, even the formula is same that v = (x)/(t)

1. If we would like to find the velocity, we must calculate the distance from initial to final, x_(f) - x_(i) = (delta)x,

2. If we would like to find the speed, we must calculate the total distance that travelled (x_(total).

So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
If you mean average speed, it is 480/10 = 48 kn/h

If you mean average velocity, it is 0/10 = 0 km/h

An arrow is shot vertically upward from the top edge of a 300 m cliff with a speed of 50 m/s, and it just misses the edge on the way down. What is its speed when it hits the base of the cliff? [91.5 m/s]
