Question

how much time will it take to perform 440Joule of work at a rate of 11watt​

Answer 1

Answer:

$\Huge \boxed{\mathrm{40 \ seconds}}$

$\rule[225]{225}{2}$

Explanation:

$\sf \displaystyle Time = \frac{Work \ done}{Power}$

$\displaystyle t=\frac{W}{P}$

The work done is 440 Joules.

The power is 11 Watt.

$\displaystyle t=\frac{440}{11}$

$t=40$

The time it will take is 40 seconds.

$\rule[225]{225}{2}$

Answer 2

Answer:

Solution

Given:

Work done=440Joule

Power=11 watt

time=?

Now,

According to the formula

Power=work done/time taken

or, 11=440/time taken

or, time taken=440/11

or, time taken=40 sec

Therefore,

40 sec will be the required time to perform 440 Joule of work at a rate of 11 watt. ans
