Assuming that the box is moving when it is being pulled, Work is done on the box.
So work is the Force times the distance
W=Fd
But what is work actually ? When something moves due to force over some change in distance, it have energy.
But where does this energy come from ? Does it magically appear ? The energy comes from the applied force onto the box.
So the energy have been transferred. And it’s like that throughout the universe
Now to save time, I’ll just tell you the answer: kinetic energy
:)

plus or minus
Answer:
0.958 m
Explanation:
So the total mass of the system is
M = 1.93 + 2.95 + 2.41 + 3.99 = 11.28 kg
let y be the distance from the center of mass to the origin. With the reference to the origin then we have the following equation



So the center of mass is 0.958 m from the origin
Answer:
the ratio is 
Explanation:
Given

The RMS velocity of molecules in a gas is given by

where T=temperature

For T = 387K

For T = 774

dividing eqn 1 and eqn 2


Thus,the ratio is
