Self-inductance:The coefficient of self inductance will rise as the solenoid's length increases because it is directly related to length: When a coil's turn count is doubled, its coefficient of self-inductance increases by a factor of four. The reason for this is that self-inductance is inversely related to the square of a coil's number of turns.
The inductance increases when the solenoid's length and number of turns are both doubled while maintaining the same cross-sectional area. The answer is "L=mu 0 N2/l A." L is doubled when N and l are both increased.
The flux that is associated with a solenoid when a unit quantity of current is sent through it is the solenoid's self-inductance.

12. The civil rights movement was a struggle for social justice that took place mainly during the 1950s and 1960s for blacks to gain equal rights under the law in the United States. The Civil War had officially abolished slavery, but it didn’t end discrimination against blacks—they continued to endure the devastating effects of racism, especially in the South. By the mid-20th century, African Americans had had more than enough of prejudice and violence against them. They, along with many whites, mobilized and began an unprecedented fight for equality that spanned two decades.
13. The first in-depth history of how domestic environments were exploited to promote the superiority of either capitalism or socialism on both sides of the Iron Curtain, Cold War on the Home Front reveals the tactics used by the American government to seduce citizens of the Soviet bloc with state-of-the-art consumer goods and the reactions of the Communist Party.
I would say the answer is C
A. The Spartans were a war like people that preferred war over diplomacy.
