Answer 1

Dear Student,

● Answer -

energy used by appliance in joules is 8.1×10^7 J.

● Explaination -

As we know 1 unit is equal to 1 kWh.

So now, 22.5 units are converted as -

22.5 units = 22.5 kWh

22.5 units = 22.5 × 1000 × 60 × 60 Ws

22.5 units = 81000000 Ws

22.5 units = 8.1×10^7 J

Therefore, energy used by appliance in joules is 8.1×10^7 J.

Thanks dear. Hope this helps you...
