Riley is upset because her friend, brendan, owes her $30. brendan claims he does not have any money, but riley saw him buying new expensive clothes last week. 1. write one closed conversation between riley and brendan. 2. write one open conversation between riley and brendan. in both conversations, be sure to show the difference in how riley starts, what she assumes, and what she shares.

Brendan: Hey, Riley

Riley: Hey, Brendan. I need to talk to you.

Brendan: OK. What’s going on?

Riley: I asked you if I could get the $30 that you owe me and you said that you didn’t have it. But I saw you in the store last week buying expensive clothes.

Brendan: Well last week was my cousin’s birthday and I needed something to wear. My mom gave me money to get something. I asked for $30 and she wasn’t able to give it to me this week because she needed to pay the bills and groceries but she told me she’ll give it to me soon. That’s why I didn’t have when you asked. I’m still trying to get it though.

Riley: I understand, Brendan. I just needed it so that I can go to the mall, but I can always get it from my mom. You can give it to me whenever you can, it’s no rush. Thanks for letting me know.

Brendan: Thanks for understanding Riley.

we need to see the examples!

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.
