When you restate the author's ideas, opinions or words in your own words, you are paraphasing.. quoting.. summarzing..

Paraphrasing.

Explanation:

Paraphrasing is an activity that involves encountering information in any form of discourse and restating the meaning and sense of the information in other words, or, in your own words. The aim of paraphrasing is to clarify, and as such, to explain further, the meaning of the information encountered: this can be aimed at one´s own comprehension or at others´ comprehension.    

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.
