for step 7 table c on the lab "newtons law of action" the average time it took the car to travel .25 meters was 1.92 seconds.
the average time it took the car to travel 0.50 meters was 2.61 seconds
hope this : )

Answer from: Quest
Answerδh > 0explanationc₆h₆ (s) → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
