Macbeth murders king duncan and is then rewarded by being crowned king himself. what recurring motif in the play is this turn of events an example of? a. the idea that bad things happen to people who listen to witches b. the idea that it is acceptable to commit crimes to get what you want c. the idea that death is a part of life and should be accepted d. the idea that actions sometimes have the opposite of the expected effect

the answer is d. the idea that actions sometimes have the opposite of the expected effect.

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.
