Aworker assigned to the restoration of the washington monument is checking the condition of the stone at the very top of the monument. a nickel with a mass of 0.005 kg is in her shirt pocket. what is the gravitational potential energy (gpe) of the nickel at the top of the monument?

The gravitational potential energy of the nickel at the top of the monument is 8.29 J.

Explanation:

We can find the gravitational potential energy using the following  formula.

Identifying given information.

The nickel has a mass , and it is a the top of Washington Monument.

The Washington Monument has a height of , thus we need to find the equivalence in meters using unit conversion in  order to find the gravitational potential energy.

Converting from feet to meters.

Using the conversion factor 1 m = 3.28 ft, we have

That give u s

Finding Gravitational Potential Energy.

We can replace the height and mass on the formula

And we get

The gravitational potential energy of the nickel at the top of the monument is 8.29 J.

it is easily magnetized.

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.
