As a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and floor become warm. during this process, energy is?

Explanation:

When the box is pushed against the floor then there will be a frictional force which will push the box in opposite direction of the force applied by the person.

Therefore, this frictional force will also release heat that will make the box and floor warm.

Hence, we can conclude that as a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and floor become warm. During this process, energy is converted to heat energy because of the frictional force.

electromagnetic waves travel through space with vacuums. give me brainliest if right.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
