What would happen to a satellite if its orbit speed was reduced by half? PLEASE ANSWER QUICKLY

The radius of orbit will increase by 4, the satellite will move away from the Earth

Explanation:

The orbital speed of any body revolving in an orbit around another boyd is given by:

v (orbital) = √(G · M(central body)/R)

Where G is the gravitation constant.

If the body, e.g satellite is moving around the Earth, then the mass of central body M will also be a constant. Therefore, the only thing on which the orbital velocity will depend on will be Radius of the orbit R.

v ∝ 1/√R

√R ∝ 1/v

Take square:

R ∝ 1/v²

If the velocity of satellite is reduce to half, then:

R' ∝ 1/ (v/2)²

R' ∝ 1/(v²/4)

R' ∝ (4)(1/v²)

R' ∝ (4)(R)

The radius of orbit will increase by 4, the satellite will move away from the Earth

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
