Part a what is the central idea of roosevelt’s inaugural address? the nation faces a corrupt banking system and overcrowded cities that will destroy the national economy. the nation faces common difficulties, but roosevelt supports the people. the nation faces nameless terrors that require new regulations to overcome. the nation faces an economic crisis that can be overcome under roosevelt's leadership and plan.

A). The nation faces a corrupt banking system and overcrowded cities that will destroy the national economy.

Explanation:

Franklin D. Roosevelt, the greatly admired president(32nd) of the United States in his very inaugural speech comes up with the central idea that 'the nation is suffering from an extreme consequences of corrupt banking system and overpopulated cities that would destroy the national economy.' He laid emphasis that the avarice and selfishness of the bankers and traders have left the nation in this state of economic crisis. Along with this he also emphasized the issue of overpopulation that has been the principal cause of staggering unemployment and urges his audience to be determined('defeating the fear of fear') to collectively cope up with this staggering situation. Thus, option A is the correct answer.

violets are black,

for what you said,

i hope you sit on a big fat tack.

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.
