A student is writing a narrative about the time her parents told her she was going to have a baby brother. The student wants to use dialogue to convey her initial unease at the news. Which two sentences best accomplish this task?

The two sentences that can best describe the feeling are as follows :

1. The initial announcement was very shocking for me like ground slipped under my feet..

2. At the initial second, my first thought was that i might loose attention and affection from my parents and would end up as second priority for them.

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.
