Which of the following relates to prewriting?
a. gathering details
b. polishing your writing
c. rewriting paragraphs
d. writing your introduction

The correct answer is:  a. gathering details  After having thought about the subject and the goal of the writing, details are collected and a brainstorm is made that is annotated informally and then the main idea is identified. Each one creates their own pre-writing strategy, which can be: making a list, developing a scheme, filling in boxes or creating a website. Pre-writing helps to organize these ideas.  

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.
