A boat floats on the surface of the water in a large but a finite-size swimming pool. How would the water level in the pool change if

(a) we take a massive block from the boat and drop it into the water? The density of the rock is larger than the density of water. (b) we drill a hole in the boat, and it begins to sink into the pool water?

Answer #1

Answers :

(a) we take a massive block from the boat and drop it into the water? The density of the rock is larger than the density of water.

Answer : According to Archimedes Principles :Aan object submerged in water will displace an amount of water equal to its volume.An an object floating in water will displace an amount of water equal to its weight. Therefore, Since we have anything massive block that is more dense than water floating in a boat and as we throw it into the water, the water level will go down.

(b) we drill a hole in the boat, and it begins to sink into the pool water?

Answer : Here the level of water will rise because the volume of boat is quite large when it will submerged in the water it will displace more water.

2. On a boat trip with friends, you are given the responsibility to make sure the boat doesn’t sink due to overloading. Your boat is rectangular in shape, with dimensions x = 1.0 m, y = 2.0 m, z = 0.50 m and a mass 45 kg. The density of water is 1, 000 kg/m3. Being the good engineer you are, you decide to test the boat’s loading capacity in a backyard swimming pool before the trip. The boat’s manufacturer...

If a person drinks a large amount of water very quickly, it is possible to exceed the rate of water removal by the kidney (~1 L/hour), essentially diluting the blood. The resulting osmotic pressure causes cells to swell. Fat and muscle cells have a capacity to adjust to this change in volume, but neurons in the brain do not have room to accommodate this size increase. (The skull is so densely packed, there is no room for swelling!) Consequently, as...

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...

CASE Wyatt Earp - The Buffalo Hunter F. Robert Jacobs, Indiana University The legend of Wyatt Earp lives on largely based on his exploits as a gunfighter and Marshall of the frontier West in the 1880s. The classic tales of the shootout at the O.K. Corral in Tombstone or his sawed-off shotgun duel with Curly Bill are possibly the most celebrated gunfights of frontier history and cannot fail to stir the reader's imagination. Wyatt lived to be over 80 years...
