"I was disappointed not to see what is inside Central High School. I don’t understand why the governor [of Arkansas] sent grown-up soldiers to keep us out. I don’t know if I should go back. But Grandma is right, if I don’t go back, they will think they have won. They will think they can use soldiers to frighten us and we’ll always have to obey them. They’ll always be in charge if I don’t go back to Central and make the integration happen" Melba Beals, Warriors Don’t Cry, African American student, 1957 President Dwight D. Eisenhower reacted to the situation described in this passage by:.

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.
