Answer 1

Answer:

300 wtts he take in 5 seconds

Answer 2

Answer:

The energy used by the light bulb is 300 J.

Explanation:

Given:

Power Consumed (P) = 60 Watt

Time for which it has been operated (t) = 5 seconds

To be Calculated :

The energy used by the light bulb when it is used for 5 seconds.

Solution:

Power is the Energy used in one second.

The formula for evaluating the power consumed is given by,

Power = Energy Used / Time Taken

So, Energy Used = Power Consumed * Time Taken

Applying the above formula and putting the given parameters in the formula to calculate the energy used is,

Energy Used = 60 * 5 = 300 J

Therefore, the energy used by the light bulb is 300 J.
