The following question refers to the analysis of media. the effectiveness of media can be attributed to its ability to
a. get away with breaking the law
d. a & b
b. be wherever people are e. b & c
c. appeal to all five senses

The effectiveness of media can be attributed to its ability to letter E: b & c. Media can be wherever people are since it has lots of branches and sometimes have the immunity to go into places just to get the news. It appeal to all five senses especially if there are pictures and videos that can ground people well.

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:

b is the answer.   i sat on the lumpy sofa, totally exhausted, with a bad taste in my mouth, wondering what i should do next.
