A) \[7.5\times {{10}^{5}}J\]
B) \[10\times {{10}^{3}}J\]
C) \[9.4\times {{10}^{3}}J\]
D) \[6.2\times {{10}^{4}}J\]
Correct Answer: D
Solution :
(d) \[6.2\times {{10}^{4}}J\] \[\text{Energy spent = power}\times \text{time}\] \[=17.42\times 60\times 60=6.2\times {{10}^{4}}J\]You need to login to perform this action.
