maximum height. What is the angle of projection? 6. A playground is on the flat roof of a city school, 6.00 m above the below). The vertical wall of the building is h = 7.00 m high, foi railing around the playground. A ball has fallen to the street below returns it by launching it at an angle of 0 = 53.0° above the horizo 24.0 m from the base of the building wall. The ball takes 2.20 vertically above the wall. (a) Find the speed at which the ball was the vertical distance by which the ball clears the wall. (c) Find the from the wall to the point on the roof where the ball lands.​

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.

explanation:

number of electrons for neutral cl

its a 5.5 n

glad that
