The following paragraph is missing a topic sentence. re-write the paragraph to include a topic sentence that states the main idea. you may want to revise the wording of the other sentences to integrate your new topic sentence. remember, while the main idea is often found in the first sentence of a paragraph, in some cases you may decide to begin with a provocative question, quotation, or piece of evidence before stating the main idea."my favorite fairy tale as a child was cinderella. i asked my parents to read the story to me every night—and i always demanded that they use different voices for each character. sometimes i would make up my own dialogue to supplement the story. when i got older, i even wrote my own stories. they were full of larger-than-life characters and magical events, just like the story of cinderella. my dream is to one day work in the film industry bringing exciting stories to life." me out

"Stories have always been an important part of my life that have held immense fascination for me, starting from when I was just a child. When I was very young, my favorite fairy tale  was Cinderella. I would ask my parents to read the story to me every night—and I always demanded that they use different voices for each character. Sometimes I would make up my own dialogue to supplement the story. When I got older, I even wrote my own stories. They were full of larger-than-life characters and magical events, just like the story of Cinderella. My dream is to one day work in the film industry bringing exciting stories to life."

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.
