What happens to the water level in a pool if a rock is thrown overboard out of a boat?
It goes down.
When the rock is in the boat (assuming the rock has a density greater than water), it displaces a volume of water greater than it's volume, enough to equal it's weight.
When you throw it over, it will only displace it's own volume, so the amount of water displaced goes down.
displace a smaller amount of water, and the water level goes down.
The last step is unclear (at least to me). In more detail:
Take the rock and put it on the ground. The water level goes down, as the volume displaced by the rock is missing. Take the rock and put it in the water. The water level goes up, but not as far as it was, as the displacement is smaller. net, it goes down.
Am upgrading from a nikon d-40 to 90 or 300s what lens would be good for boat ride pics with landscape/fishin?
If you will be in wet/salty weather the D300 is better than the D90 because it is weather sealed better. And in that environment you may not want to be removing and changing lenses which will expose the internals to the weather so you might want a zoom lens with a wide range of focal options. 18-200mm etc......
To "rock the boat" means to cause trouble.
"Should we rock the boat?" there must be more information...
Such as: the rules for lunch period are strict, but should we rock the boat?
Should we possibly cause trouble for ourselves and others by questioning the rules
Think about it literally: if you rock the boat...it may tip over, dumping you in the water
I hit a rock with my boat and the motor was stuck down. It will not go up only down?
If the "release" failed to allow the engine to come up when you hit a rock, that shock could be transfered to the Hydraulic assembly and damaged the valving.
For an engine that is that old, I would consider getting a new one to replace an engine that is twenty years old. The parts to repair it will cost more than it is worth.
Your other option is to remove the damaged "Lift" cylinder, plug the lines and raise and lower it by hand until the engine is just worn out in a couple more years down the road. Provided the lower end isn't' toast from the hit.
What do I have? I just came from a cruise and have been feeling nauseated, like Im still in a rocking boat?
You have motion sickness on land..its quite common.. Most people will be on a boat for a while and then when they get on to land and have what they call "jelly legs".. the feeling of still being on a boat rocking back and forth..It will eventually get better in a day or two..You wont feel that way.. Your being hungry, however, may have somethign to do with the nausea if you havent eaten enough..it could be your body telling you to eat something or it could be compeletly un-related
How did Aaliyah the girl who sings rock the boat die.?
plane crash. pretty self explanatory she was in an airplane and it crashed
she and eight others died in a plane crash in the Bahamas on August 25, 2001 after filming the music video for the single "Rock the Boat".
What causes you to keep your "sea legs" after getting off a boat?
Your legs adjusted to the movement of the ground. now that it stopped moving it wont stop enduring the rocking sensation.
Hope that helps ^_^

A person is in a boat in a swimming pool. He throws a rock from the bottom of boat into the pool. What happens?
the water level decreases. imagine an extreme situation. suppose you have a very, very dense rock from a planet in another galaxy. imagine this rock is very small, but very very heavy (for example its volume is 10 cm^3 but its weight is 10000 kg). and you have a large pool with a large boat on it. now, you place the rock in that boat. now, because the rock is very heavy, the boat is almost sink, with the water level very high in boat's body. mark the water level in pool's wall. now, you throw the rock into the pool. because a large weight is released, the boat rises, the water level decreases. the water level in pool's wall will be decreased either. put it another way: if the rock is contained in a boat, it can displace large amount of water. but if it is thrown into the pool, it can only displace exactly 10 cm^3. so, the water level decreases.
that video used to be one of my favorites especially since it was sorta like a 'alright I'm grown now yall' type videos in my opinion lol and I was in HS thinking I was grown of course so I could relate. Was sad that she died so young though :-(
Why does it always feel like I am on a rocking boat?
You're land sick. It's perfectly normal. It will eventually go away, but it's unpleasant in the mean time. I find that making tea from ginger root helps a lot. If you don't have any ginger root, try some ginger ale.
Are you a mover and shaker or a calm person who does not like to rock the boat?
In most situations i calm things down, when ppl get all shaken up they don't think straight. They don't see the answers that could be reached by logic. Now i'm not saying i'm always calm about my opinions and ideas, if i gotta rock the boat for people to see what i have to say then tip it.
What happens to the water level when boat drops rock?
F = weight of water displaced
When the rock is in the boat, it causes the boat to sink, raising the water.
For a boat with sharp edges:
Force of Rock = Area of Boat Bottom*Depth Displaced*Density of Water
When you toss a rock in the water (and it sinks), the volume displaced is equal to the volume of the rock.
In general, the volume displaced by the boat with a large rock is larger then that the rock itself.
Say a piece of granite ~3 g/cc and 1000 cc, so 3000 grams. The volume displaced by the boat is going to be 3000g/1 g/cc (the density of water), or 3000 cc. Compare this with the 1000 cc if the rock is thrown in - less water is displaced, and lake falls in level.
This will be true for any substance more dense then water.
What is the origin of the phrase "don't rock the boat"?
"rock the boat" was actually The Hues Corporation and not Tony Orlando and Dawn.
In any case, "Rock the Boat" started with William Jennings Bryan in 1896 ("The man who rocks the boat ought to be stoned when he gets back on shore." ), but was certainly current in the administration of Theodore Rooosevelt (who would often go boating). A political "rock the boat" headline involving both Taft and Roosevelt appeared in 1908.
What to do about loud, obnoxious neighbors when you don't want to rock the boat?
are they really loud or are you used to house living?
I mean there is a certain amount of noise in apartments, so examples would help.
I'd contact the property company only after I spoke with my neighbor directly. If you are sincere about your issue and not b.itchy, snobby or demanding you may be able to fix the noise with a simple conversation with your neighbors. If not, move out when your lease is up. Or keep a noise log and contact the property management to inquire about them dropping the fees to break your lease since you have noise issues.
It's probably a combination of getting the attention off of them, making themselves look better, bitterness and stress, and just genuine nastiness.
I deal with it every day, so you aren't alone!!
Stay strong, and know that you are great, no matter what.
