How successful are marches in order to gain/improve social equality?

Very Successful

Explanation:

I'm just stating my opinion. Going on marches or protests helps put whatever problem you are having out there for people to see. It's a way to get your point across. Think of Martin Luther King. He had marches and they turned out very successful.  Same with George Floyd.

alright, so here, the author clearly thinks that flooding the canyon was a bad idea and is showing bias against it.

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.
