How long will it take a 500 watt electric motor to do 1.5 x10^5 j of work

                  Power  =  (work)  divided by  (time to do the work)

                         500 joule/sec = (1.5 x 10⁵ J)  /  (time)

Multiply each side
by time:                    (time) x (500 joule/sec)  =  1.5 x 10⁵ J

Divide each side
by 500 J/sec:            Time = (1.5 x 10⁵ J) / (500 J/sec)

                                            = (1.5 x 10⁵ / 500)    (J-sec/J)

                                            =   300 sec

                                            =  5 minutes .      

It's have to be 12 or idk

When you go to ask a qustion there will be a picture of a paper clip looking thing and then it will pop up your files and you click on the imajes and then you up load it
