Who was friends with lawremcr

John

Explanation:

Father John is a Franciscan friar and a friend of father Lawrence. Father Lawrence trusts John so much that he sends him to Mantua to deliver an important message for Romeo. John is supposed to let Romeo know that Juliet´s death had been staged so they could be together. However, before reaching his destination, father John is held up in a quarantined house, so Romeo never gets the message.

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.
