Question

power
How much time will be required
to perform 260 J of work at the
rate of 13 W?​

Answer 1

Step-by-step explanation:

__________________________________

⚡Formulas to remember:-

1) P=w/t

2) t=p/w

____________________________________

:-Initial condition

Work done=260Joules

Power required=13Watt

___________________________________

There is no final condition hence time required is:-

$p = \frac{w}{t}$

$t = \frac{w}{p}$

$t = \frac{260}{13} = 20sec$

Hence time required is 20 seconds.
