the answer a: perseverance !

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.

i am a strong (insert gender here) my father and his brother were to, they were killed not by the cold, not by the bears or wolves that roam our streets at night, but by the   bolsheviks. we must stand up and fight communism or we all end up dead, starved dehydrated, enslaved. the time is now we must fight. lenin is a dangerous man but he can be stopped. so my comrades we shall siege there weapons tonight on ward.
