Which of these lines from "the story of an hour" describes mrs. mallard's initial reaction upon learning of her husband's death?
a. there was something coming to her, and she was waiting for it, fearfully.
b. the vacant stare and the look of terror that had followed it went from her eyes.
c. her pulses beat fast, and the coursing blood warmed and relaxed every inch of her body.
d. she wept at once, with sudden, wild abandonment, in her sister's arms.

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:

the answer is industry
