If you view a complete free body diagram of a moving object, what two aspects of the body's motion will the diagram show?

Magnitude and direction of the net force acting on the body

Explanation:

The free body diagram of a moving object shows all the forces acting on the object. In particular, every force is represented by an arrow, whose length is proportional to the magnitude of the force and whose direction represents the direction of the force.

Therefore, from a free body diagram it is possible to estimate the net force. In fact, by analyzing separately the forces acting along the horizontal direction and the forces acting along the vertical direction, one can estimate the net force acting in each of the two directions. Then, these two forces represent the components of the resultant force (net force) acting on the object.

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.
