Answer 2

$\bold{ \fbox{ \fbox{ \huge{Given :- \: }}}}$

$\to \bold{Work = 1000 \: J} \\ \to\bold{</p><p> \: Time = 10 \: Sec}$

$\fbox{ \fbox{ \bold{ \huge{To \: Find :- \: }}}}$

$\to \bold{Power = \: ? \: }$

$\fbox{ \fbox{\bold{ \huge{Solution :- \: }}}}$

$\underline{\bold{ We \: Know \: That \: , \: }}$

$\to \fbox{ \bold{ \huge{ \: \: Power = \frac{Work}{Time} \: \: }}}$

$\to \bold{Power = \: \frac{1000}{10} } \\ \\ \to\bold{Power = \: 100 \: \: watt}$

$\bold{ \therefore \: \underline{ \:Power \: Is \: 100 \: Watt}}$
