Please help with this exercise! It's from a pdf, but I don't know how is it called so I can download it with answers...

your answer would be: d) eye contact

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:

it depends on how u want ur relationship to go, if u want something serious or not.   if u are to go on a first date go to somewhere nice, comfortable, and fun. don't make it so romantic because u can make the other person uncomfortable. don't make moves so fast and keep things chill.never force the other person to do things they don't want to do.

explanation:

it would be d because the however is more proper and the comma is placed in the right spot
