Convection is a means of heat transfer that involves fluids, such as liquids or gasses. The process of convection is responsible for air and water currents as in the illustration. As the temperature of fluids increases their molecular motion increases, therefore as fluids warm their density decreases. A classroom demonstration of convection involves placing a small covered container filled with warm water to which food coloring has been added into a large container of cold water.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

this would be about 43%

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
