Who or what was faustus talking about when he said oh, thou art fairer than the evening air clad in the beauty of a thousand stars; (scene 13, lines 101–102)   

Helen of Troy

Explanation:

Helen of Troy is a famous classical figure, and she is often presented as the paragon of excellence. She is brought back to life by Faustus because she is considered the most beautiful woman in the world, and she also serves as a symbol for Faustus's most base desires. While he had initially wanted to make the blood pact in order to acquire knowledge, he now seems dominated by his desire to possess her, and to indulge in other worldly pleasures.

- "he is a very real person and his intent isn't to influence us vonnegut addresses this towards the end of the letter when he says, if we choose to curse, that is by our own individual means."

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.
