A) 9.8 kW
B) 120 kW
C) 1.2 kW
D) 1200 kW
Correct Answer: A
Solution :
Given, mass of water \[(m)=100\,\,kg\] Time \[(t)=10s\] Height\[(h)=100m\] Acceleration due to gravity \[(g)=9.8m/{{s}^{2}}\] Power (p) = ? We know that, \[p=\frac{mgh}{t}\] \[\Rightarrow P=\frac{100\times 9.8\times 100}{10}=9800\,\,W\]You need to login to perform this action.
