Power is a scalar quantity. The S.I. unit of Power is Watt (W). In other terms, we spent one Watt of Power while completing one Joule of Work in one second. 1 Watt = 1 Joule / 1 second. Other units of Power are Kilowatt (kW), Megawatt (MW) and Gigawatt (GW). The relation between units of Power: 1 kW = 1000W, 1 MW = 1000000W and 1GW = 1000000000W.
If the unit of power is 1 kilo watt, the displacement is 100 m and time 1 s, then the unit of mass will be? View Solution. Q 3. The half-life of radium is 1620 yr and the atomic weight is 226 kg per kilo mol. The number of atoms that will decay from its 1g sample per second will be (Take Avogadro's number N A =6.023×1023 atom/kilo mol).
Moreover, the standard unit of measuring power is Watt. According to the power formula, a unit of power is equal to a unit of work divided by a unit of time. Also, a watt is equal to Joule/ second. Besides, due to historical reasons, power is occasionally used to describe the power delivered by a machine. In addition, one horsepower equals 750 ...
