When was the research administered?

It is a phenomenon of producing induced current in a coil by changing the magnetic feild around the coil is called Electromagnetic induction.

When magnetic feild is changed uniformly around a conductor an E.M.F is used inside the conductor which produces electric current.

Electromagnetic induction is the basic principle of electric generator.

Hello!

If a runner exterts 350 J of work to make 125 W of power, then how long did it take for the runner to do the work?

We have the following data:

W (work) = 350 J

P (Average Power) = 125 W (or 125 J/s)

Δt (time) = ? (in seconds)

An average power in working relation with the time spent, we have the following formula:

Solving:

The time it took for the runner to do the job was 2.8 seconds
