Travis sets up and experiment to determine and predict the velocity of a marble at the end of a track. He uses an electronic balance to weigh the marble and a set of calipers to measure the width of the marble. He then places the marble at the top of the track and releases it. Travis then uses the time it takes the marble to pass through a photogate at the bottom of the track to calculate the velocity of the marble. Travis notes that his prediction is significantly lower than his calculated velocity. Which error explains this difference?
A) He forgot to account for friction.
B) He forgot to zero the balance and found a weight for the marble that was too low.
C) He weighed the marble in a weighing dish and failed to account for the mass of the weighing dish.
D) He didn't position the photogate correctly and got the time required for the top of the marble to pass through, rather than to the middle.

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)

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
