PLEASE HELP MEI WILL GIVE BRAINLIEST AND 45 POINTS!!! Reflect on your one act play. What do you think you did well? What do you wish you could do better, or had done better? In general, what type of errors do you tend to make in writing? (spelling, commas, etc.)

I think I did everything pretty well. I only wish I could do one thing better because I didn't like how it came out. I mostly made errors in commas and sometimes made errors in spelling. But after all that I think I did good.

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.
