Kay, so me and my teacher, Mila Nikol said that Spider-Man *Peter Parker* is better than Iron-Man *Tony Stark* like what??? She wants me to write an essay on both parties. Yes, the only reason I have to do this is because I argued with her about it lol *I had facts, she had theories, so I won lol.*

good luck

Explanation:

hate to break it to ya but, Spider-man is s  much cooler than iron man!

Explanation:

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:

depressed people should not argue
