Which of the following is describing exposition? A. Michael’s teacher was trying to finish her lesson quickly, before she lost the students attention B. the bell finally rang and Michael darted out of the classroom heading for the bus C. it was Friday afternoon and Michael was ready for the school bell to ring.

☁️My Answer☁️:

I believe the correct answer option is C.) It was Friday afternoon, and Michael was ready for the school bell to ring, because exposition is a comprehensive description and explanation of an idea or theory, which means this answer option is the most descriptive because it says it was on a Friday unlike the other answer options because they only give detail about what happened inside the classroom and it doesn't give as much detail as much as option C.

(I do indeed apologize if this is incorrect.)

I hope you do enjoy the rest of your day!  (ɔ◔◡◔)ɔ ♥

d) sarah's natural reaction to being accepted into college suggests that she has no other dreams.

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.
