Consider a carousel rotating at angular velocity w6 relative to an inertial frame fixed to the ground with origin o. there is a clown on the nonrotating wall (into whose mouth you want to throw a brass ring) located at a vector position rco relative to o, the center of the carousel. you are on a horse fixed to the carousel (ignore its up-and-down motion) at position ro. what is the velocity of the clown (rate of change of rc/h) relative to you (i. e., in the body frame of the carousel) in terms of wb and rc/o? (see example 8.5.) 8.5

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

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.
