7. A methanol powered car produces CO₂ when it runs. Does that mean it is contributing to global warming? (A) No, if the methanol was produced from recently living biomass (B) Yes, if the methanol was produced from recently living biomass (C) Yes, if the methanol was produced from solar power (D) No, if the methanol was produced from natural gas. 8. The density of compressed natural gas is 60 grams per liter. If a car were powered by an engine that burned natural gas (similar to a gasoline engine), how large a compressed natural gas tank would it need to have the same range as a standard gasoline car? (A) about 3 times bigger than a standard car's gasoline tank (B) about the same as a standard car's gasoline tank (C) about 20 times bigger than a standard car's gasoline tank (D) about 10 times bigger than a standard car's gasoline tank
Decide how the sketches below would be listed, if they were listed in order of decreasing force between the charges. That is, select "1" beside the sketch with the strongest force between the charges, select "2" beside the sketch with the next strongest force between the charges, and so on. Note for advanced students: since the units of each charge are not written, you may assume any convenient and reasonable unit, for example coulombs or multiples of e. +2 +1 O 1 (strongest) 02 3 O 4 (weakest) O 1 (strongest) O 2 3 O 4 (weakest) +1 -1 O 1 (strongest) O 2 3 O 4 (weakest) O 1 (strongest) O 2 3 O 4 (weakest)
