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.
Wires A as well as wire B are both made out of copper. Both of wires have the same length. The diameter of wire B is doubles that of wire A. Answer: Resistivity is a charac
