how many decibels does the sound level increase if the intensity of the sound increases by a factor of 3?

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
