Shaleen sir,i want to know If 1kWh=3.6*10000000J,then 1J=---kWh;If 1hp=746W then,1W=---hp;if 1w=1J/s then,1J=---W?what is meant by resistive force and magnitude of resistive force?-M.Manaswini,anantapur

Pls. post each question individually.
1 W = 1/ 746 HP
1 J = 0.28 x 10-6 kWh
Resistive force is the force which opposes the motion or the cause producing it.
Magnitude of resistive force refers to its numerical value.
