Question

How has the discovery of a clay cooking pots artefact shaped historians’ understanding of life in Ancient China?

Answer 1

The cost of electricity is equal to 50paise

Solution -

Power of kettle =500W =0.5kW

Time =30 mins =0.5 hours

Electricity consumption will be power multiplied by time. So,

Electricity consumption is :-

0.5 multiplied by 0.5 = 0.25 units or

0.5*0.5= 0.25 units

Cost of 1 unit (or 1kwh) is Rs 2. So,

Cost of the electricity consumed is equal to :-

0.25 multiplied by 2 = Rs 0.50 = 50paise

KEY POINTS TO REMEMBER -

1000 watt = 1 kilowatt

Energy = power multiplied by time

I hope this helps you. If it's OK please mark the answer brainliest. Have a good day. :-)
