Voter Registration in the South: 1960: White: 61.1% African American: 29.1%

1970: White: 62.9% African American: 62%

—Statistical Abstract of the United States, 1990

What evidence supports the idea that equality has been achieved based on the percentage of people from each group who vote?

A. By 1970, the percentage of African Americans and whites voting was nearly equal.

B. By 1960, the same percentage of African Americans and whites were voting.

Fewer African Americans were voting in 1970 than in 1960.

C. Fewer African Americans were voting in 1970 than in 1960.

Nevermind it's A

i think the answer is c. she can't feel happy because things are moving too quickly.

answer: c

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.
