Why did Mr. Fisher not speak up at the meeting about the football team? Why was he
squirming in his seat?

Mr. Fisher did not speak up at the meeting because he did not know which side to choose. If he chose Mrs. Fisher's side he would anger coach, but if he took coach's side he would anger Mrs. Fisher. This would also be the reason why he was squirming in his seat, he was nervous about the argument and how it is going to end up. He didn't want things to get heated between coach and Mrs. Fisher because it will also effect his relationship with the coach but he also does not want this to get in between the "Eric Fisher Dream".

Explanation: (Pg. 58)  "I looked at Dad, sitting back on the couch next to Mom. His whole body was stiff, rigid, like he was dead. What would he do? Would he publicly take Coach Warner's side against Mom? Or would he defend her and anger Erik's coach?"  On this page, it includes when the meeting was held and on this paragraph, it includes why Mr. Fisher was so silent. I also used prior knowledge of the book for the "Eric Fisher Dream" part.

yh it is right

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.
