Which of these did Frederick Douglass use in his writing to build credibility, or
ethos?

I believe the answer to be objectivity

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:

plagiarism is a consequential action, and can result in many bad endings. for instance, you could possibly get expelled from a college or even your own school. you also have the potential of getting your work destroyed. it can also result in expulsion from you academic institution, in some cases permanent expulsion. plagiarism can result in legal action; fines and penalties etc.

hope this , and have a good day. c;
