Afirefighter directs a stream of water travelling at 35.0 m/s from a fire hose at angle of 32.0° above the horizontal towards a building. the end of the hose is 1.00 m above the level ground. the water hits the building at a height of 17.6 m from the ground as shown in the diagram below. assuming that there is negligible air resistance and that the water is projectile, determine how far the firefighter is from the base of the building.

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.
