What is the stated claim in the following argument? i should not have to go to school today. my cat had to be taken to the emergency room last night and i barely got any sleep. i don’t really have any important tests or anything. what good would it do for me to get into a car wreck on the way to school because i fell asleep at the wheel?
a. i should not have to go to school today.
b. my cat had to be taken to the emergency room.
c. i barely got any sleep.
d. i don’t really have any important tests or anything.

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.
