star a is 4 light ears away from earth. star b is 10 light years away from earth. when you observe both stars from earth they appear to have the same brightness. how do the stars apparent magnitudes compare?

Umm sorry I don't know how to answer this question

Explanation:

sorry can't answer

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.
