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

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
