Power=Work/Time
The work done is the energy required to lift the box, fighting the force of gravity. So, Work=Potential energy of the box at 10 meters.
W=PE=mgh=(60)(9.8)(10)=5880J
Finally,
P=W/T=(5880)/(5)=1176Watt
So the answer is 1176 Watts
Scientists could investigate this idea by making cathode ray tubes out of different materials to see if the ray was the same.
Chlorine forms hydrochloric acid when reacted with hydrogen
