A coyote that is carrying an anvil steps off of a high cliff. Fortunately, the coyote has a parachute so, when it opens, they both fall at a constant velocity of 1500 ft/min.

a) How long does it take the anvil to hit the ground?
b) What is the velocity of the anvil right before it hits the ground?

the one with the highest speed

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:

double the distance = divide strength by 4

i think it would be 5
