The Flintstones and Rubbles decide to try out the new inclined bowling alley, ``Bedslant Bowling''. Fred's ball and Barney's ball have the same size, but Barney's ball is hollow. Wilma's ball and Betty's ball are scaled down versions of Fred's ball and Barney's ball respectively. They all place their bowling balls on the same pitch incline and release them from rest at the same time. (greater than,, less than, equal to)
The time it takes for Wilma's ball to hit the pins is that for Barney's ball to hit.
The time it takes for Barney's ball to hit the pins is that for Betty's ball to hit.

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)
