If a 0.7 kg object hanging from a spring stretches it by 0.20 m, then by how much will the spring be stretched in ma 1.2 kg object is suspended from it?

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.

a=d/t

a="triangle"v/t

explanation:

a = acceleration

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
