When a spring is compressed, its potential energy is increased. Specifically, the form of potential energy that increases is called elastic potential energy. The correct answer is "elastic potential energy."
When a spring is compressed, work is done to compress the spring, and this work is stored in the spring as potential energy. The potential energy is stored in the spring in the form of potential energy associated with its deformation, which is called elastic potential energy. When the spring is released, the stored potential energy is converted back into kinetic energy, which causes the spring to expand or oscillate.

The mass of the platinum if the volume is 113 cm³ and density is 21.4 g / cm³ is 2.418 kilograms or 2 kilograms and 418 grams.
The density is the mass of a material substance per unit volume. d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density.
As an illustration, the density of Earth is 5.51 grams per cubic centimeter, whereas the density of water is 1 gram per cubic centimeter.
Given:
The volume of the platinum disk, V = 113 cm³,
The density of platinum, d = 21.4 g / cm³
Calculate the mass using density and mass relation as shown below,
density = Mass of the platinum / Volume of the platinum
21.4 = Mass of the platinum / 113
Mass of the platinum = 21.4 × 113
Mass of the platinum = 2418.2 g
As we know 1 kg = 1000 grams,
Mass of the platinum = 2418.2 / 1000
Mass of the platinum = 2.418 kg
Thus, the mass of the platinum is 2.418 kg.

B. Have neutrons in their nuclei.
C. Have an equal number of electrons and protons
D. Have an equal number of neutrons and protons
Atoms have no electric charge because they have an equal number of electrons and protons.
Explanation:
So from this, we can conclude that atoms have no electric charge because they have an equal number of electrons and protons. Option C is correct.
