Take a look at "Remembering Gandhi." Think about the following statement by the leader of South Africa's anti-apartheid movement, Nelson Mandela: "In a world driven by violence and strife, Gandhi's message of peace and nonviolence holds the key to human survival in the 21st century."

Mandela probably made this statement in order to .

A Predict that most 21st century leaders would choose to adopt the practice of satyagraha
B Imply that he followed Gandhi's practice of satyagraha in his fight against the apartheid in South Africa
C Note the shared qualities of South Africa's and India's struggles in the fight against discrimination
D Persuade the reader to join Gandhi's peaceful campaign for Indian independence form the British.

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.

second one- because has facts and not opinion
