What is the relationship between first-person point of view and bias?
a. because first-person point of view is the most personal, the narrator's version of events is often opinionated
.b. because first-person point of view shares the thoughts of many characters, their feelings are out in the open.
c. because first-person point of view is told from the perspective of the narrator, the outlook is usually objective
.d. because first-person point of view is the most impartial, the characters' emotions rarely come into play.

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.
