Yes, those are my intuitions. Meaning, if the the rock were less dense than water, it would displace the same amount of water (its weight) whether it was in the boat or tossed out to float -- in which case the water level wouldn't change if it were tossed overboard. Not positive about this...

I don't think so, not as long as the rock isn't so massive that it sinks the boat. Assuming that, no matter the volume of the rock, the weight of the denser-than-water rock will displace more water (raising the level of the pool) when it is "artificially" buoyed up in the boat than it would...

Not sure why this thread was moved here. It's got nothing to do with homework nor am I in any course. Whatever. I think the water level goes down. That is based upon a comparison of the water displaced by the rock when in the boat (its weight) vs. the water displaced by the rock when...

I think that my subjective intuitions are not compelling to me even if they happen to be correct. I do not have sufficient facility with the relevant equations to prove the answer. That's what I'm looking for help with. (I think I'm also trying to figure out what kind of question...

You're floating in a boat in a pool with a 100 pound rock in the boat. You carefully measure the water level of the pool. Then you toss the rock out of the boat into the water. It sinks to the bottom. Does the water level of the pool go up, down or stay the same? Quantitative...

A number of questions have come up on canoe forums relating to the “buoyancy” of different woods out of which paddles can be made. The general issue has been to make the most “buoyant” paddle. Generally, here’s the goal. In certain canoe strokes called in-water slice returns, you don’t lift...

The research paper can be read here by clicking on the Article in Physical Review Letters link. The paper describes the images as "electron momentum distributions" that demonstrate "coherent electron scattering". I'll leave it up to someone more knowledgeable to explain what this means...

I'm interested in this statement from the paper: "In the simulation model, the photons have which-way information, never have direct communication with each other and arrive one by one at a detector. Although the photons know exactly which route they followed, they nevertheless build up...
