Consider an object undergoing a rotational motion in the xy-plane about a fixed axis perpendicular to the plane of motion. let o be a point in the xy-plane, point p will move in a circular path with a radius latex: rr = 0.8 m. the relative position of point p along its circular path is given in meters as a function of time latex: s\: =\: 0.45\: t^{\frac{4}{3}}s = 0.45 t 4 3. determine the distance (s) traveled by point p along its path, and the magnitude of its linear velocity (v), tangential (at), normal (an), and net accelerations 3s after the motion began.

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:

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
