Imagine a plane leaves Ronald Reagan airport and travels along vector A northeast towards Annapolis. When it reaches the city, the plane turns toward the northwest to reach Baltimore travelling over vector B. Next it turns back to the southwest, takes vector C to Dulles airport and returns home on vector D. Now imagine you start from the same position, but this time your first trip goes in the direction of vector B. Then you travel by vector C, D, and finally A. What is your destination this time

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.
