It’s the year 2078, and you’re traveling from Earth to the Moon. To determine how much fuel you need for the rocket ship, you measure your mass upon boarding. When you land on the Moon, your Mass hasn’t changed. Your Weight, however, has changed. You feel lighter because the Force of gravity is lower.

Explanation:

I got this right on Edmentum. Have a great day and I hope this helped!

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.
