Acar accelerates from rest along a straight road. as it accelerates, the magnitude of the car's momentum changes by a certain amount. by how much does the magnitude of the momentum of the earth itself change? 1. we need more information about the force of friction between tires and road that accelerated the car. 2. a much larger amount since the earth has a much larger mass 3. the same amount 4. a much smaller amount since the earth has a much larger mass 5. none of these

Tornadoes form in unusually violent thunderstorms when there is sufficient (1) instability and (2) wind shear present in the lower atmosphere. elaborate on what does instability mean when discussing the formation of a tornado? a) dry air in the middle atmosphere being rapidly cooled by rain b) winds at all levels of the atmosphere are strong and turn with height c) an isolated strong thunderstorm just ahead of a squall line that merges with the squall line d) very warm, humid conditions in the lower atmosphere; cooler than usual conditions in the upper atmosphere
