In chapter five, bilbo meets gollum. this is why bilbo feels sorry for gollum even though gollum wants to harm him, gollum is miserable and alone, and he has no hope for a better life. gollum has no sword and has not actually tried to kill bilbo. bilbo finds gollum's ring. bilbo knows that gollum's family was killed by smaug.

c. to understand which information will best persuade your readers. (apex) correct answer.

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.
