Q:

The amount of energy it takes to lift a box might be a function of which of thefollowing?

Accepted Solution

A:
Answer:the weight of the objects inside the boxStep-by-step explanation:Given that a box is lifted and we have to calculate the factor which influences the amount of energy it takes.We have energy = work doneWork done = Force x displacementForce = mass x accelerationHere acceleration=acceleration due to gravity and this remains constant irrespective of shape of box, weight or time of dayThus we getenergy taken = work done= Force x displacement= mghwhere h = height liftedg= acceleration due to gravitym = mass of the boxHence we find that II option  the weight of the objects inside the box is right.
