When zitkala-sa resists having her hair cut at her new school in "the school days of
an indian girl," the teachers react with brute force and violence. this episode illustrates?

Their failure to understand and respect Native American's beliefs, traditions, and cultures.

Explanation:

Her teachers in the school had bad reactions on her situation which is showing us that they are not understanding and respecting her culture and tradition.

Violence and brute force in Schools are against the law and they are punished.

This is also showing a sort of discrimination because they didn't even try to understand her situation and tradition so they are immediately shown disrespect of her culture.

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.

well basically since ima beginner people will answer any subject "right away"and if you get more points you could ask more questions or if you answer someone's question you get points
