What do I do? I have a friend that I haven’t talked to in a while and I worry we are losing our friendship. It doesn’t help that I’m an anxious and over thinker, It makes me think that they don’t want to be my friend.

( Extra info: When i say hi or what’s up I don’t get a response. Sometimes I’m left on read. We have Houseparty and because i see there online I text them. I say hi to talk to them but no response. It makes me feel ignored )

I want to bring this up to them but don’t know how and I’m pretty scared I need opinions :(

Honestly you should try calling them or meeting up in person.

Explanation:

Be sure to wear a mask though! :)

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.
