Question

Calculate the time it takes a 200 W appliance to transfer 40,000 J of energy

Answer 1

`power = (workdone)/(time \: taken)`

`p = (w)/(t)`

200 = 40,000 / t

200t = 40,000

200t / 200 = 40,000 / 200

t = 200s

Answer 2

Step-by-step explanation:

P=energy used/time taken

200=40000/t

200t=40000

divide both sides by 200

t=200s
