Which of the following is the best example of one-way listening? a dialog between a husband and wife a dialog between a woman and her dog a political speech a classroom conversation next

The best example of one-way listening is a political speech.

Explanation: One-way listening occurs when the listener receives and interprets information but he/she does not say anything in response to it. When one-way listening takes place, there is no interaction between the listener and the speaker because the listener never becomes a speaker. When listening to a political speech, the listeners only process the information presented by the speaker. In other words, the only speaker during a political speech is the politician: there is no interaction between the people that listen to that speech and the speaker.

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.
