A) 100 W
B) 1 Kw
C) 10 kW
D) 100 kW
Correct Answer: D
Solution :
Key Idea: Power is the rate of energy transferred. \[\text{Power}\,\text{=}\,\frac{\text{enegy}}{\text{time}}\] or \[P=\frac{mgh}{t}\] ?(i) Here, \[\frac{m}{t},100\,kg/s,\,g=10\,m/{{s}^{2}},\,\,h=100\,m\] Substituting the values, we obtain \[P=100\times 10\times 100={{10}^{5}}W=100\,kW\]You need to login to perform this action.
