Which is a characteristic of auto biography

An autobiography is a self-written book about a person's life (the author writes a book about himself)

Characteristics of an autobiography:

Usually written in 1st person: autobiographies are written by a person about their own life, therefore they use I, me, and my when writing.

They usually contain a Chronology: A chronology is usually listed in the back of the book, listing the important dates and events on that date

i believe it true i guess because you are the one that is writing so you should know what you are putting in your essay.

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.
