1. The term that best describes Styrofoam is "composite". This is because Styrofoam is made up of two main components - 98% air and 2% styrene. It is a composite material that combines these two elements to create a lightweight and insulating material commonly used for packaging.
To arrive at this answer, I analyzed the provided information about Styrofoam and its composition. By understanding that Styrofoam is made up of two distinct components, it becomes clear that it falls under the category of composite materials.
2. The best choice for Bryan's component that needs to carry an electric current from one part of the computer to another would be "copper". Copper is a highly conductive material and is widely used in electrical wiring due to its excellent electrical conductivity.
To determine the best material for carrying electric current, it is essential to consider the properties of different materials. Copper, specifically, is known for its high electrical conductivity, making it an ideal choice for such applications.
3. The term that represents the measurement of power being put into an electrical circuit is "voltage". Voltage refers to the electric potential difference between two points in an electric circuit, which is responsible for the flow of electrical current.
To find the answer, I identified the provided options related to electrical measurements and carefully compared them. Among the given terms - conductivity, electron, current, and voltage - only voltage is directly associated with the measurement of power in an electrical circuit.
1. The term that best describes Styrofoam is "composite" because it is made up of a mixture of air and styrene derived from petroleum oil.
2. The best choice of material for Bryan's component that will carry an electric current from one part of the computer to another would be "copper." Copper is a good conductor of electricity.
3. The term that measures the power being put into an electrical circuit is "voltage." Voltage is the potential difference between two points in a circuit and is measured in volts.
