Answer:

so the time taken will be 120 seconds

Explanation:

power=30W

work done=3600J

time=?

as we know that

[tex]power=\frac{work done}{time taken}[/tex]

evaluating the formula

power×time taken=work done

[tex]time taken=\frac{work done}{power}[/tex]

[tex]time taken=\frac{3600J}{30W}[/tex]

[tex]Time taken=120seconds[/tex]

i hope this will help you :)
