Answer 1

P ( POWER) =. H / T

T = 30 × 60 = 1800.

60 = H / 1800

H = 1800 × 60 = 108000 .

Answer 2

Answer:

The electrical energy consumed in joules is 108000J.

Explanation:

Given:

       Power = 60 watt

       Time = 30 minutes

To Find:

        The electrical energy consumed in joules.

Solution:

        Firstly, converting 30 minutes into seconds.

       Time = 30 minutes

                   = 30× 60

                   = 1800 seconds

$Power = Energy/Time$

       $Energy= power*Time$

           = 60 × 1800

           = 108000J

 Converting into kilojoule

                           108000$J$ = 108$KJ$
