How does Adams attempt to explain the mysterious appearances of the hitchhiker?

by using his theories and information from others. The second time he sees the hitchhiker he says that the fast truck could have picked up and dropped him off before Adams got to the destination. He asked questions at the gas station to try and understand the raindrops on the hitch hikers shoulders to determine if someones will be hitchhiking at Pennsylvania turnpike. He also tries convincing himself it's a coincidence. He later decides it's a phantom or ghost when he picks up the girl he tries discussing how the hitchhiker might be able to arrive to places faster than others in a car.

Explanation:

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.
