He looked at me sideways—and i knew why jordan baker had believed he was lying. he hurried the phrase "educated at oxford," or swallowed it, or choked on it, as though it had bothered him before. and with this doubt, his whole statement fell to pieces, and i wondered if there wasn't something a little sinister about him, after all. which theme does this excerpt best convey?

People shouldn't try to be who they're not because the truth will reveal itself

Explanation:

a. the man as a ruler

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.
