Read this excerpt from "The Light of Gandhi's Lamp" by Hilary Kromberg Inglis, in which she describes driving to the police station where her sister is being detained. To avoid looking at the blackened windows at the top of the building and thinking about the history of who had died or been tortured there, I always looked instead at the little Chinese restaurant on the opposite side of the road. How does this passage affect the text

It conveys the view held by many anti-apartheid activists that the police often acted in brutal and unlawful ways.

She always did not want to look at the direction of the building to keep away the memories of the death and sufferings the people suffered from unlawful police officers during the apartheid period.

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.
