Question

A machine performs 24 joules of work in 4 seconds. The power developed by this machine is ?

Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:= \: 6W }}}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━

To find power used by the machine we will use this formula

$\LARGE{\bf{\underline{\underline\color{purple}{Formula :-}}}}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Power \: = \: \frac{work \: done \: }{time \: taken \: } }} }\\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Power \: = \: \frac{ 24 }{4 }\\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Power \: = \: 6W }} }\\ \\\end{gathered}\end{gathered}$

Answer 2

Solution -:

Given,,,

work = 24 J

time = 4 s

Required

6W

To find -:

power developed by this machine

Let's Begin -:

We know that

Formula ,,

$\large{ \sf{power = \frac{total \: work \: done}{time} }}$

$\large{ \sf{p \: = \frac{w}{t} }}$

now,, substitute,,

$\displaystyle \large{ \sf{ = \frac{24j}{4} }}$

$\large{ \sf{ \pink{ = 6 w}}}$

A machine performs 24 joules of work in 4 seconds. The power developed by this machine is 6 W
