How do you think your presence has had impact on the lives of the students in this classroom whom you are interacting with?

this is literally about your opinion but here's 2 answers

Explanation:

short but effective: we all hear about "the butterfly effect" or "every action has an equal and opposite reaction" the same goes for people. If you have a positive and kind demeanor/presence then people around you will tend to be more positive as well. What we put into the classroom is what we get out

simple and easy:

My willingness to participate and my willingness to act kind all has an effect on the people in the class. if I have a positive presence, others around me will as well. If I have a negative presence, other around me will as well

(I TRIED TO MAKE THEM NOT LONG BUT I CAN WRITE MORE IF NEEDED)

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.

explanation:

the answer is definitely d. sorry for a late response.
