2. a. as you push a conductive loop into a magnetic field, energy is produced (as current flows through a resistor). where does this energy come from? b. a sheet of aluminum, with its normal oriented due west, falls vertically toward the earth’s surface. as it falls, it encounters a uniform magnetic field that is directed due west. (i) viewed from the east (i. e. looking west), what direction do the eddy currents flow in the sheet as it enters the field? (ii) viewed from the east (i. e. looking west), what direction do the eddy currents flow in the sheet as it leaves the field? (iii)the current dissipates electrical energy. in what form is that energy before the sheet has entered the field? (iv) in what form is that energy after the current has ceased to flow?

c, 1a hope this

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.

explanation:

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

measure their densities same density, same sub
