Imagine you are in a small boat with a large stone sitting in the bottom of it. The boat is floating in a swimming pool. What happens if you throw the stone overboard? Does the level of the water in the pool go up, down, or stay the same?
the boat is a 16 foot alumium row boat
the rock is an average WNY style rock, weighs 100 pounds, isnt lavarock or anything liek that. could also substitute a 100 pound block of concrete if you want … so whatever you want to use to figure the rocks diplacement based on its weight will work, as long as you dont try to say the rock is made of buble wrap
it will stay the same, overall. The water level in the pool will rise a bit due to the rock in the pool, but the boat will not be as heavy, and will sit higher in the water and not displace as much, making the water level the same.
yep. end of thread. we dont even have to get into density of the rock vs the boat and how much the water would go down. cuz then people will come in here talking about lava rocks vs shale vs blah blah blah. water level goes down
I would think that it would stay the same because the rock being in the boat causes the boat to displace the water, they you take it out and throw it in, it would negate itself because the rock is now displacing the water, not the boat.
Basically, you are using the boat as a “middle man” to displace the water, then you eliminate the middle man, just like Gieco, and the water level does not change.
Once you take the rock out of the boat, the boat displaces less, but you put the rock in the water, then it displaces the same, that is, unless it is lava rock or shale or some shit like that… Then you need to get into astrophysics and shit, like how dogs and cats live together, and how the theory of relativity will cause me to probably go to O tonight, but only if I am bored.
Water is constantly evaporating so the water level will go down eventually unless there is a source to refill the pool.
The stone will also absorb some of the water so the displacement would not be the same.
If the stone is heated to molten magma the water will evaporate faster than normal.
The rock could also splash some of the water out off the pool if thrown properly.
If the stone is thrown overboard onto the deck of the pool the water level would go down.
Etc, etc, etc.
first person to build a boat out of 60 popsicle sticks or less and test this in 4 gallons of water gets a cookie.
two cookies if you go to awdrifters extremem and heat the rock to molten state lol
the surface area of the boat in far greater than the rock… all the rock provided was weight, which allowed more of the boat to be under water, which made water rise.
take the rock out, and the boat goes up, water level lowers. throw the rock in the water and the water level will rise, but not to the original height.
