Answer:

1800 joule

Step-by-step explanation:

Power (P) = 30W

Time (T) = 1 min =60 sec

P =(W/T)

30 = W / 60

W = 1800 joule

We know that Energy Is equivalent to Work done. So Energy used is 1800 joule.

Answer:

1800 j or 1.8 kj

Step-by-step explanation:

Energy used = power (measured in watts) multiplied by time (measured by seconds)

1 minute is 60 seconds

30 multiplied by 60 is 1800
