Apower plant has 4 tons of coal. a ton of coal produces 2460 kilowatt hours of electricity. is this enough to power 9 light bulbs for a year? explain.

Yes

Step-by-step explanation:

We will assume that each bulb is of 100 kW (kilowatt).

We will calculate how much energy in kilowatt-hours the light bulb will use per year in kilowatts, by the number of hours in a year.

We have,

100 kW = 0.1 kW so the energy consumed in one year is,

Since there are 8760 hours in one year.

It is given that there are 9 bulbs so we need to have,

It is given that 1 ton of coal produces 2460 kWh, so 4 tons of coal will produce,

We can observe that 4 tons of coal is producing 9840 kWh which is mroe than 7884 kWh. So, yes, 4 tons of coal can produce enough power to light 9 bulbs for a year.
