As a person pushes a box across a floor, the energey from the person's moving arm is transfered to the box, and the box and the floor become warm during this processes what happens to energey? a it is increased
b it is conversed
c it is decreased
d it is created

Protons and neutrons are found within the nucleus of an atom

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
