O Search 13. Ranking Task #172 6. If a wave travels at a speed of 8 m/s and has a wavelength of 2 m, what is its frequency? O 6 Hz O 16 Hz o 4 Hz O 10 Hz Simple Resistor Circuits-Voltage Drop12 All the resistors in the circuits below are identical t 2 each. The batteries are ideal with voltages of 6 or 12 volts as shown. All connecting wires have negligible resistance Rank the voltage at the upper right-hand comer relative to the ground. Place the highest voltage first and the lowest voltage last. 7. Which of the following is NOT a property of sound waves? O The speed of sound waves in air depends on the temperature of the air O The pitch of a sound wave is closely related to its frequency O The loudness of a sound wave is related to its amplitude and frequency O Sound waves can travel through empty space 8. Which of the following describes a major difference between gases and liquids? O Liquids can exert a buoyant force on objects, but gases cannot O Gases can be compressed, but liquids cannot O Liquids obey conservation of momentum, but gases obey conservation of energy o Waves can travel through liquids, but they cannot travel through gases 9. If two electrons are placed 1 m apart, which of the following describes the electric force they'd feel? O They would feel a force that pulls them toward each other O They would feel a force that pushes them away from each other O They would not feel any electric force at all Lowest Highest Or, all of the voltages are the same. Please carefully explain your reasoning 10. If two light bulbs are connected in parallel and one breaks, what will happen to the second light bulb? O The second light bulb will remain lit at the same brightness O The second light bulb will remain lit, but at a lower brightness O The second light bulb will remain it, but at a higher brightness O The second light bulb will also go out 11. If two light bulbs are connected in series and one breaks, what will happen to the second light bulb? O The second light bulb will remain lit at the same brightness O The second light bulb will remain lit, but at a lower brightness O The second light bulb will remain it, but at a higher brightness O The second light bulb will also go out 12. Which of the following could cause the strength of the electric force between two charged particles to become twice as strong? Fill in all that apply. O Doubling the charge on the first particle O Doubling the charge on the second particle O Moving the particles to double the distance O Moving the particles to half the distance The obiect has an electric charge
