Asmall puck with a mass of 0.10 kilograms is sliding in the +x-direction on an air table with an initial speed of 8.0 meters/second. the puck collides with a larger puck that is initially at rest. the larger puck has a mass of 0.40 kilograms. after the collision, the smaller puck has a speed of 3.4 meters/second at an angle of +60° from its original path. the angle made by the larger puck is -35°. what is the x-momentum after the collision if the velocity of the larger puck after the collision is 1.5 meters/second? 0.8 kilogram meters/second 1.5 kilogram meters/second 2.1 kilogram meters/second 3.6 kilogram meters/second 4.8 kilogram meters/second

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.
