Upton sinclair's the jungle was published in 1906. which is a good note to write for this key event?
a.) the book made the american public aware of the plight of the immigrant.
b.) the book rallied support for reform in the meat industry.
c.) jurgis, the main character, work in the meat industry.

i think you should write from the heart and think what truely makes a hero. i can’t do this for you. even though this is it’s up to you.

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.
