Amachine does 2500 j work in 1 minute what is the power developed by the machine?

The Power developed by the machine will be "41.67 W".

The given values in the question are:

Work done,

Time,

or,

As we know the formula,

→

By substituting the given values, we get

→                  

→                  

Thus the above answer is right.

Power = (work done) / (time to do the work) <== Memorize this !

When you use this formula, the work done has to be in units of Joules, and the time to do the work has to be in units of seconds.

Power = (2500 J) / (1 minute)

Power = (2500 J) / (60 seconds)

Power = (2500/60) (J/sec)

Power = 41.67 watts

technology is the application of the knowledge gained by science.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
