Question
A certain household has consumed 250 units of energy during a month. How much energy is this in joules?
Answer
Given:
Energy consumed = 250\text{ units}1\text{ unit} = 1\text{ kilowatt-hour (kWh)}1\text{ kWh} = 3.6 \times 10^6\text{ J}
Calculation:
Energy in Joules = 250 \times 3.6 \times 10^6\text{ J}= 900 \times 10^6\text{ J}= 9 \times 10^8\text{ J}
Answer:
The energy consumed is 9 \times 10^8\text{ J}.
