If an object aquires additional energy, it is also aquiring additional: a) taxes b) vitamins c) mass d) pressure e) buoyancy

Option c) mass

Explanation:

With the increase in energy in energy of an object there will be an increase in its mass.

Also from Einstein's mass-energy equivalence,

where

m = mass of the object

c = speed of the object (usually speed of light or close to it)

which states that energy and mass are inter convertible.

From which it can be concluded that if an object acquires additional energy, it also acquires additional mass.

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.
