Can someone me with tkam questions im stuck. ill message you

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:

it’s important not to respond to the bully because doing so generally just escalates the problem.

tell a trusted adult about what is happening and save the evidence. you should also let your internet or cell phone provider know, along with the operator of the site if it is happening online.

if the bullying continues, notify the local police and consider consulting an attorney if it becomes serious.

school authorities may also become involved if it involves students on campus.
