a cj said to me, "ashton, you should still come to the awards ceremony even if you can't stay for dinner."
b cj said to me, "ashton you should still come to the awards ceremony even if you can't stay for dinner."
c cj said to me "ashton, you should still come to the awards ceremony even if you can't stay for dinner."

That would be A

Explanation: You always put a commas after the last word before it starts a quote and when a proper noun is used, with or without quotes, place a comma after it.

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.
