Tonya is thinking about the topic presented in the text, "do opposites really attract? " which of her thoughts is an example of critical thinking? a. "this wouldn't be a saying if it wasn't true." b. "what is meant by 'opposites'? is this referring to looks, personalities, interests, backgrounds, or education? " c. "i'm attracted to people who are different from me so that is evidence that the statement is true." d. "everyone i know is dating or married to someone who is completely different from them so this must be a universal truth."

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

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.
