A dog might signal the whistle of a tea kettle or the beep of a microwave oven. Simple sentence

Compound sentence

Complex sentence

Compound sentence

Explanation:

It has to parts, but the second one can't stand on its own and make sense, so Its dependent.

'A dog might signal the whistle of a tea kettle' or 'the beep of a microwave oven.'

A simple sentence is one independent clause, meaning it can sand on its own and make sense.

A compound sentence is one independent clause and one dependent clause linked by a conjunction.

A complex sentence is two independent clauses linked by a conjunction.

a. inform

explanation:

"how to" tells us that it will explain how to, which means to inform

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.
