The atomic radius of a hydrogen atom is 53 pm. The radius of a golf ball is 21.35 mm. If the hydrogen atom was blown up to the size of the golf ball, how big would the radius of the golf ball be if the original size ratio is maintained

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

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.
