Using a lever
Determine that the longer end of a lever travels farther and faster than the shorter end when the fulcrum is not in the centre. A baseball or cricket bat makes use of this benefit. List other examples of the use of levers and other simple machines to enhance speed.
The internal energy change when a system goes from state A to B is 40 kJ/mole. If the system goes from A to B by a reversible path and returns to state A by an irreversible path wh
