2. What type of speech context refers to communication that focuses on one person, in which the speaker acts as both the sender and receiver of the message?
A. Interpersonal
C. Mass Communication
B. Intrapersonal
D. Public Communication

So Iterpersonal So A.

Explanation:

Interpersonal centers in one person where the speaker acts both as the sender and the receiver of the message. Interpersonal refers to communication between and among people and establishes personal relationship between and among them.

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.
