Question

a certain household has consumed 50 units how much energy is this in joule
​

Answer 1

A certain household has consumed 250 units of energy during a month. How much energy is this in joules? 1 unit of energy is equal to 1 kilowatt hour (kWh). Therefore, 250 units of energy = 250 — 3.6 — 106 = 9 — 108 J.

Answer 2

here is yøur answer

Energy consumed by certain households in a month E=250 units =250 kWh

Energy consumed by certain households in a month E=250 units =250 kWh∴E=250×3.6×106 J (∵1kWh=3.6×10 6

J (∵1kWh=3.6×10 6 J)⟹E=9×10
