Why do you think the boss never went to see his son’s grave? (From “The Fly.”)

The story states that it has been six years since his son was killed in the war, and the boss has not gone to see the grave yet. It is possible that the boss does indeed intend to never visit the grave site, but that is conjecture on the part of the reader. Therefore, what readers do know is that the boss is still emotionally crushed by the death of his son.

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.

this isnt an english question.
