1. Sound is important because it engages audiences: it helps deliver information, it increases the production value, it evokes emotional responses, it emphasises what's on the screen and is used to indicate mood. When put to good use, language, sound effects, music, and even silence, can elevate your video dramatically

2. Dark colors absorb a lot more heat than lighter ones because they absorb more light energy. In fact, the closer to black a color is, the more heat it absorbs from light sources. The key is that colors do not absorb different amounts of heat, only heat from light

3. Brain imaging has shown that when we hear an unpleasant noise the amygdala modulates the response of the auditory cortex heightening activity and provoking our negative reaction.

4. Copper wires are usually covered with rubber or plastics to prevent shocks and ensure safety. Because plastics and rubbers are insulators of electricity i.e. they cannot conduct electricity.

5. Conductors and insulators are both important in the field of electronics. Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.

When put to good use, language, sound effects, music, and even silence, can elevate your video dramatically.

2.Darker colors absorb more light. Since light is energy, absorption would increase a material's temperature. This means that, darker colors become better radiators of heat. It is important to note that an object appears white if it reflects all colors and black if it absorbs all colors.
