Answer the following question given this paragraph: The speed of most waves depends on the medium through which they are traveling. Generally, waves travel fastest through solids and slowest through gases. That's because particles are closest together in solids and farthest apart in gases. When particles are farther apart, it takes longer for the energy of the disturbance to pass from particle to particle. Q: Do waves move faster when particles are close to each other or far away? Choices: - unaffected - far away - open - close A:
close
Answer the following question given this paragraph: Electronic components are the parts used in electronic devices. They are made of p-type and n-type semiconductors. Examples of electronic components include diodes, transistors, and integrated circuits (microchips). Q: What are diodes, transistors, and integrated circuits examples of? Choices: - computer parts - radio parts - machine parts - electronic components A:

Q: Answer the following question given this paragraph: Most geological activity takes place at plate boundaries. But some activity does not. Much of this intraplate activity is found at hot spots. Hotspots are plumes of hot material that rise through the mantle. Hotspot volcanoes erupt when the hot material melts to create magma. Q: Where does most geological activity takes place? Choices: - in mountain ranges - at ocean bottoms - in coastal areas - at plate boundaries A:
A: at plate boundaries
