The mechanical advantage of a machine is the ratio of the force produced by the machine to the force applied to it. Therefore, we may calculate the applied force using:
Mechanical advantage = force by machine / force applied
6 = 2 / force applied
Force applied = 1/3
Thus, the distance that the effort must move will be 1/3 inch
Answer:
The value is
Explanation:
From the question we are told that
The speed at which galaxy B moves away from galaxy A is
Here c is the speed of light with value
The speed at which galaxy C moves away from galaxy B is
Generally from the equation of relative speed we have that
Here p is the velocity at which galaxy C recede from galaxy A so
=>
=>
=>
=>
=>
I=22 ÷20
