P = W / T
1500 × T = W
NOW
1 hr = 3600 sec
10hr = 36000 sec
1500 × 36000 = W
[calculations
15 × 36 × 100000
540 × 100000
54 × 1000000 ]
54 ÷ 10^(6) = W
I.E
THE ANSWER IS
54 ÷ 10^(6) J
1500 × T = W
NOW
1 hr = 3600 sec
10hr = 36000 sec
1500 × 36000 = W
[calculations
15 × 36 × 100000
540 × 100000
54 × 1000000 ]
54 ÷ 10^(6) = W
I.E
THE ANSWER IS
54 ÷ 10^(6) J

As we know that power=work done/time
1500=w/36000
(10hrs=36000seconds)
1500*36000
540*10^5 J energy required
