Imagine that in a remote location near the North Pole, a chunk of ice floats in a lake. Next to the lake, a glacier with the same volume as the floating ice sits on land. If both chunks of ice should melt due to rising global temperatures, and the melted ice all goes into the lake, which one would cause the level of the lake to rise the most? Explain.
Two
streams merge to form a river. One stream has a width of 8.1 m, depth of 3.6 m, and current speed of 2.2 m/s. The other stream is
6.3 m wide and 3.8 m deep, and flows at 2.5 m/s. If the river has width 10.7 m and speed 2.9 m/s, what is its depth?

- The Huka Falls on the Waikato River is one of New Zealand's most visited natural tourist attractions. On average, the river has a flow rate of about 300,000 L/s. At be gorge, the river narrows to 20-m wide and averages 20-m deep. (a) What be average speed of the river in the gorge? (b) What is the average speed of the water in the river downstream of the falls when it widens to 60 m and its depth increases to an average of 40 m?arrow_forwardConsider a river that spreads out in a delta region on its way to the sea. Construct a problem in which you calculate the average speed at which water moves in the delta region, based on the speed at which it was moving up river. Among the things to consider are the size and flow rate of the river before it spreads out and its size once it has spread out. You can construct the problem for the river spreading out into one large river or into multiple smaller rivers.arrow_forwardYou drill a small hole of area 0.0013 m2 near ground level on the side of a 18.3 m high, very large water tower reservoir.
