Answer 1

The answer is 650*3.6*10^6 joules

Answer 2

Given :

The energy consumed by the house in a month = 650 units = 650 kWh.

We know that 1 kWh = 3.6 × 10^8 J

So the energy consumed by the house in joules =

= 650 × 3.6 × 10^8

= 2340 × 10^8

= 23.40 × 10^10 joules.

Definition of 1 kWh :

Energy consumed in 1 kWh if a machine or appliance of 1 kilowatt power is operated for a period of 1 hour.
