A given package of 50k is moved across the floor with an applied force while accelerating at 4m/s^2 A) Draw a freebody diagram of ALL the forces (4 of them: applied, gravitational, friction, normal)
B) Determine the net force on the package
C) If the frictional force on the package is 100N, then determine the applied force necessary to accelerate it.

answer: he got 23

explanation:

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.
