Pl help quick 25 points Five friends were talking about forces. This is what they said. Which friend do you agree with the most? *
Rae: I think a push is a force and a pull is something else.
Scott: I think a pull is a force and a push is something else.
Yolanda: I think a force is either a push or pull.
Miles: I think forces are neither pushes nor pulls. I think they are something else.
Violet: I think pushes and pulls are forces, but there is also another type of force that just holds things in place.

Explanation:

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.
