How does the repeated phrase support King's message?
Read the excerpt from Martin Luther King Jr's "I Have a
Dream" speech
But one hundred years later, the Negro still is not free. One
hundred years later, the life of the Negro is still sadly
crippled by the manacles of segregation and the chains of
discrimination. One hundred years later, the Negro lives on
a lonely island of poverty in the midst of a vast ocean of
material prosperity
D by emphasizing that time has passed without social
progress
by suggesting that freedom will come eventually without
effort
by insisting that people cooperate to achieve a common
goal
by hinting that all Americans should strive for material
wealth

A. By emphasizing that time has passed without social progress.

Explanation:

Repetition is a literary device that repeats the same words or phrases a few times to make an idea clearer and more memorable.

He is emphasizing that, even one hundred years later, African Americans are still not free from oppression.

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.
