An engine does 6000 joules of work in 20 seconds. What is the power of this engine?

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you

Because its reliable.   there is no pollution  the chances of a radiation leak is low
