Neglecting air resistance which of the following statements is not true regarding the motion of a ball thrown vertically with an initial speed velocity of 10 meters per second A. the velocity of the ball is at its peak is 0.0 meters per second
B. the force of gravity is constant and does affect the ball's velocity
C. the ball's velocity when caught is 10 meters per second
D. the ball is in the air a total of 2.04 seconds

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.
