What's a good way to write an introduction paragraph for an expository essay?

Use it as an introduction and introduce what your going to be writing about in it.

Explanation:

An introduction is basically giving a very brief description of the contents of the paragraph. In a introduction paragraph, you want to briefly but clearly state what your going to be writing about.

answer: a. the image doesn’t give relevant information .

explanation: they’re clearly talking about bees in the bullet points, the picture shows a man doing what ? holding paper, its ot relevant.

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.
