Question

If a satellite moves above Earth’s atmosphere in a circular orbit with constant speed, then

its acceleration and velocity are always in the same direction

he net force on it is zero

its acceleration is toward the Earth

its velocity is constant

t will fall back to Earth when its fuel is used up

​

Answer 1

Answer:

which among the following was not backed by US ? (a) Cento (b) Warsaw packt (c) seato (d)nato

Answer 2

Answer:

The orbit is actually elliptical, but it is treated as circular for easier calculations.

The satellite is orbiting with constant speed.

The satellite's velocity is always changing.

The satellite is accelerating because there is a net force acting on it.

The force of gravity on the satellite is the centripetal force.
