Maye is running an experiment to determine if a car with large tires will move faster than a car with small tires. her ramp is 0.7 m long she recording the following times on each of her trials: trial 1: 2.5 seconds, trial 2: 2.75 seconds, trial 3: 2.98 seconds. what was the average speed of her car?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
