Do you think that protest is a good tool to change a social or political situation?

no

Explanation:

to be honest soemtimes it can help in a good way to change poilitical terms and racial opnions because it shows how much care goes into a certain race, idea or opnion, but other than that protesting isn't a good thing nor is it bad (Its mostly bad, but people only take it t the level of protesting if there not being heard, or if something exttreme happens tot here race, THATS when you should protest)

hope this helps and pls mark brainlest!!

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.
