Select the correct answer from each drop-down menu. Participants are assigned different roles for a group discussion. A(n)
introduces the topic to the group. A(n)
keeps the group on task, tracks the time, helps resolve conflicts, and takes notes on the main points of the discussion. A(n)
listens to the presenter and provides feedback on the points being presented.

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.

explanation:

in the story "marionettes inc," in the last line of the story, braling two is referred to by the narrator as the "someone." what does this new identifier imply and how does it add to the drama of the closing scene?

my best guess would be: d allusion

makes the most sense

the symbol of the grandfather's heritage in this excerpt from "the medicine bag,” is the beaded bolo tie.

a bolo tie is a cord fastened around the neck with an ornamental clasp which is worn as a necktie. they have been used by native american tribes such as hopi, navajo, zuni, and puebloans since the mid-20th century.

therefore, the fact that the grandfather is wearing a bolo tie refers to his heritage as native american.
