1. What is the relationship between the length of time a force has an impact on an object and the impulse exerted on the object?
2. In a car crash why is it advantageous for an occupant to hit an airbag rather than the steering wheel? Explain your reasoning in terms of impulse, force, and time.
3. If the popper took four times longer to snap, what would've happened to the force of the snap? What data would you reference as evidence to support your reasoning?

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)
