Imagine that you have been asked to speak at a pep rally for your high school’s football team on the day of a big game. You will be in front of the entire student body and will be tasked with celebrating the team’s past wins and the skills of the coach and players in a 5 - 10 minute presentation. List at least 4 of the characteristics of public speaking (ie. message, channel, noise, audience, context, and delivery) that you should be most concerned with in preparing for this speech and explain why.

explanation:

the star of david was known as the jewish star : d

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.

they are all talking about chocolate (next time you post a question with "which" post the choices too)
