A 0.45 Caliber bullet (m = 0.162 kg) leaving the muzzle of a gun at 860
m/s. what is the momentum?
140 kg*m/s
140 kg
62 kg*m/s
387 kg*m/s

139.32kgm/s

Explanation:

Mass(m)=0.162kg

Velocity(v)=860m/s

Momentum=mass x velocity

Momentum=0.162 x 860

Momentum=139.32kgm/s

where are the vectors ?

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.
