Which statement is the strongest thesis for the writing prompt? during world war ii, great britain was under heavy attack by german forces and required the efforts of all british citizens in order to defeat hitler. the british government created a series of national service posters to be posted around the country. in a series of posters, the british government employed a variety of persuasive techniques to convince people to join the war effort.

In a series of posters, the British government employed a variety of persuasive techniques to convince people to join the war effort.

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.
