Which of the following best describes the use of a non-renewable resource? Question 2 options: Wind turbines gather energy from the wind and convert it into electrical energy. Water falls through openings in a dam turning turbine blades that generate electricity. The electronic signs along the highway are run by solar power. Nuclear energy heats water into steam that turns the turbines of a power plant

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:

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

iron would move it is magnetic there is a mag field around the current in the wire

no sign of dia of fuel cell
