Tahj walks 28 m south from imhotep's front doors in order to get into his mothers car. if it takes him 7 s, what was average velocity?

i believe it is b. what was the cause of the big bang

hope this !

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.
