Anna drives north at a speed of 50 km/h for the first hour. then, she drives north for a second hour but slows down to 30 km/h. compare or contrast the first hour of her trip to the second hour of her trip.

group of answer choices

the distance is greater in the first hour because her speed is faster.

the distance is greater in the second hour because her speed is slower.

the displacement is the same for both hours because she is travelling north the entire time.

the distances are the same for both hours because she is travelling north the entire time.

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)
