Question

A classroom has 24 fluorescent bulbs, each of which is 32 W. how much energy does it take to light the room for a minute?(unit=J)PLEASE HELP

Answer 1

The answer should be 46100 (J)

Step-by-step explanation:

It'd be correct for Acellus students

Answer 2

46.08KJ

Step-by-step explanation:

Given the power needed to light one bulb is 32W

We know that Power=energy/time

Therefore the energy needed to light one bulb is
`power*time`

Given time= 1minute= 60 seconds.

Energy =
`32W*60sec` = 1920J

energy recquired to light one bulb is 1920J

The energy recquired to light 24 bulbs is =
`24*1920J=46080J=46.08KJ`
