How much time would it take to exert 700W of power while doing 700J of work?

The answer to your question is time = 1 s

Explanation:

Data

time = ?

Power = 700 W

Work = 700 J

Power is defined as the work done per unit of time.

Formula

Power = Work / Time

-Solve for time

Time = Work/Power

-Substitution

Time = 700 / 700

-Result

Time = 1 s

Conclusion

In 1 second and with 700 J there will be produced 700 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.
