Directions, Part 2: Read each of the following sentences then write a sentence using the same pattern. For example, if the sentence is: Those are the people who took our seats when we left to get popcorn. you then might write: Those are the books that we left in the library. Henry’s boots are uncomfortable so he tried to return them to the store.
The boys threw themselves down and tried to hide from their mothers.
Don’t worry; I myself will be the one onstage tonight.
The bus lost its wheels and it crashed onto their lawn.
Everyone wanted to see another movie so we stayed at the mall.

the animal shelter ad with animals in cages, starving and dying.

explanation:

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.

explanation:

the direction of the magnetic field produced by an electric current will change when the direction of the electric current changes. for example : if a current is flowing in a straight length of wire, the magnetic field is described by a concentric circle (using right-hand rule).
