Suitable technology was not available to disprove the model.

Answer 2

A satellite orbiting Earth at an orbital radius r has a velocity v. Which represents the velocity if the satellite is moved to an orbital radius of 4r?(1 point)
Responses

1/4v

4v

1/2v

2v

Answer 3

The correct response is "1/2v." When a satellite is moved to an orbital radius that is four times larger (4r), its velocity (v) will be halved (1/2v).
