Read the following paragraph and identify the Object of Prepositions: Mark Twain loved to brag about his hunting and
fishing exploits. He once spent three weeks fishing in the Maine woods, regardless of the fact that it was the state's closed season for fishing. Relaxing in the lounge car of the train on his return journey to New York, his catch iced down in the baggage car, he looked for someone to whom he could relate the story of his successful holiday.

what is the question here?

i don't see anything attached can you attach something?

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:

c) eager anticipation.
