Two cars enter the florida turnpike at commercial boulevard at 8: 00 am, each heading for wildwood. one car’s average speed is 10 miles per hour more than the other’s. the faster car arrives at wildwood at 11: 00 am, hour before the other car. what was the average speed of each car? how far did each travel?

The average speed of the cars is 50mph

Explanation:

Option C

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.
