The si unit of power is watt
Now
Power=Work(J)/time(sec)
Here we need time in hours so
1sec=1/60 min=1/(60*60)hrs=1/3600hrs
Power = 1000/3600
=0.278watts
Now
Power=Work(J)/time(sec)
Here we need time in hours so
1sec=1/60 min=1/(60*60)hrs=1/3600hrs
Power = 1000/3600
=0.278watts

o. 278 watt hours
in 1000 joules
wait let me check
ok
the question is wrong or the answer is wrong
cuz the unit doesn't match
Ans: 1kwhr = 3.6x106J
1whr = 3.6x106J/103
1whr = 3.6x106-3J
1whr = 3.6x103J
1whr/3.6x103 = 1J
0.000278whr = 1J
1000x0.000278watt hr = 1000x1J
0.27778watt hr = 1000J
1whr = 3.6x106J/103
1whr = 3.6x106-3J
1whr = 3.6x103J
1whr/3.6x103 = 1J
0.000278whr = 1J
1000x0.000278watt hr = 1000x1J
0.27778watt hr = 1000J
ok
this is the corect and proper answer
