The phrase "20 m/s to the east" is an example of a a. velocity b. time c. position d. acceleration

The phrase “20 m/s to the east” actually represents a velocity variable. In this case, we can see that the velocity is of vector type. That is, it contains a magnitude and direction:

magnitude = 20 m/s

direction = to the east

A. Velocity

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.
