No Discussion Topic
As American colonists questioned British rule, public discussion focused on topics such
as colonial independence and individual rights. In turn, literature from the American
Revolutionary period often reflected important political and social themes, including
national independence, personal liberty, and individualism. In your opinion, how does the
literature of this period influence future generations of American literature? Where have
you seen traces of these themes and how were they presented in the other literature you
read?

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.

explanation:

i also think it is d (sorry if it's not)
