Ahair curling iron uses 13 watts of power. how long must it operate to do 1,040 joules of work?

Knowing the solution to the 4-watt night light, you ought to be able to do this one on your own.  But 5 points is 5 points, so here we go:

1 watt = 1 joule/second .

                            (1,040 joule) / (13 joule/second)

                        =    (1,040 / 13) (second)

                        =       80 seconds .  

Power of Watt = Energy in Joules / Time period in seconds

13 watts = 1040 joules / time in seconds
time in seconds = 1040 joules / 13 watts
time in seconds = 80 seconds

It must operate for 80 seconds to do 1,040 joules of work.

Ifound this on google “how does an observation of an object differ from an inference about it? observations uses one or more of the senses to gather in formation and record it but an inference is a logical interpretation of the prior knowledge like testing samples.” i hope this you for what your looking for. can you plz mark me brainliest?
