Aparticle moves with uniform velocity. which of the following statements about the motion of the particle is true? a. its speed is zero b. it's acceleration is zero c. it's speed may be variable d. acceleration may be variable

B

Explanation:

when a velocity is uniform it means it may not variable over time

and it mean the particles acceleration is 0

50 inches should be the resultant vector

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.
