The ratio of the distance moved by the point at which the effort is applied in a simple machine to the distance moved by the point at which the load is applied, in the same time. In the case of an ideal (frictionless and weightless) machine, velocity ratio = mechanical advantage. Velocity ratio is sometimes called distance ratio.
The answer to your question is -4
Answer:
17 h
Explanation:
The command sent to the Voyager I is a radio wave signal, which travels at the speed of light:

The distance between the Voyager I and the Earth is

So, the time taken for the signal to reach the probe is

Consindering that the number of seconds in 1 hour is

Then the time elapsed converted into seconds is

Momentum is defined as the the product of mass and velocity of an object.

So the two things on which determine an object's momentum is:
1. mass of the object
2. velocity of the object
