How did Roosevelt's audience for his Four Freedoms speech present a
challenge?
Not everyone in his audience agreed with what he was proposing.

Not everyone in his audience agreed with what he was proposing.

The "Four Freedoms" were the goals stated by President Franklin D. Roosevelt in the 1941 State of the Union address. Roosevelt also explained the participation that the United States was to have in the Second World War.

Many Americans did not want the U. S. to get involved in the war due to the terrible experiences of WWI. Therefore, Roosevelt's audience did not agree with him for the most part. However, the commitment included aid to allies, but not direct participation.

The speech proved to be one of the most popular speeches in history.

Explanation:I hope I can help you :)

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.
