If a vector a has components a. 0, and ay -0, then the magnitude of the vector is negative. select one: true false

False

Explanation:

The magnitude of the vector is the absolute value and also the magnitude is defined as the amount or quantity posses by the body or the resultant of any vector.

The magnitude is always absolute it is always positive it can never be negative.

The magnitude of vector is,

So, this can never be negative.

Given whether if the the vector A has component A, 0, and Ay-0, the magnitude of any vector is always positive.

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.
