In a loop-the-loop ride a car goes around a vertical, circular loop at a constant speed. the car has a mass m = 228 kg and moves with speed v = 16.74 m/s. the loop-the-loop has a radius of r = 11.3 m.

1.what is the magnitude of the normal force on the care when it is at the bottom of the circle? (but as the car is accelerating upward.)
2.what is the magnitude of the normal force on the car when it is at the side of the circle (moving vertically upward)?
3.what is the magnitude of the normal force on the car when it is at the top of the circle?
4.compare the magnitude of the cars acceleration at each of the above locations:

a. abottom = aside = atop
b. abottom < aside < atop
c. abottom > aside > atop
5.what is the minimum speed of the car so that it stays in contact with the track at the top of the loop?

A.

ride. You estimate thatch tofind that each loopp

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.
