Would dropping an anchor into the water from a boat displace more water than before?
An old chestnut this one. Whilst in the boat, the anchor displaces its weight in water, when under the water and lying on the bottom, it only displaces its volume. As it is made from iron which is much denser than water, its volume is much less than the volume of water which equals its weight. So it will displace less water than before it is dropped.
What is the definition of water displacement?
If you were to submerge a cube that is 1MX1MX1M in water you would "displace" or move one cubic meter of water. The cube would be where water was, so it is said that the water was displaced. One measure of a ship is how much water is displaced when the ship floats. Something that is floating will displace its own weight in water.Water displacement moes the water so you can tell the volume of an object. Also... Displacement is a measure of mass as in a ship's displacement. A ship will displace the amount of water equal to it's mass or weight. The amount of water displaced, by volume, can vary depending on whether the ship is in salt water or fresh water. A ship will displace less water in the ocean than it will, let's say in a river. A gallon (US) of sea water weighs about 8.55lbs (3.88kg), while a gallon (US) weighs about 8.35lbs (3.79kg). If the same ship were in a river or lake of fresh water it would sit lower in the fresh water then it would in the ocean. Ocean's water, being heaver, is then more buoyant.
Why ship is floating?
An object in water displaces its weight in water. If its volume is greater than the volume of water displaced this way, it floats. Ships, despite being made of heavier materials, utilize their size and their relative empty insides to float this way.
Describe two ways to compare the densities of unknown substances?
You can always compare the densities by the formula d=m/v, where m is the mass and v is the volume . However; a simpler technique is to put the objects in some water . The densities can be compared by how much water each of them will displace.
What happens to the pressure and the molecules inside a beach ball that is being blown up?
Imagine you are putting the balloon in a tank of water. Assume the balloon has X volume. It will displace that much water. When you inflate the balloon with Y liters of air, you add the two volumes together. You would now displace X+Y liters of water. I hope that's right. Essentially volume now equals volume of balloon+volume of air.
How much weight does your boat displace?
The Joke: Not much it sank The truth: A floating boat will displace the same weight in water that it weighs. So the real question is how much does it displace or how much does it weigh

How does a 1.3 billion pound boat float?
It must displace as much weight in water as it weighs (roughly 600 cubic meters of water). These boats have huge hulls, so can easily displace this much without beginning to sink.
If a penny fell from an aircraft into a swimming pool would it displace more water if it fell directly into the pool or if it fell into a toy boat that was floating in the pool?
In theory the same amount of water would be displaced in each case; i.e. the coin landing in the boat would cause the boat to displace additional water (sink slightly) equal to its own volume, which is how much the coin would displace were it to fall directly into the pool. This assumes, however, that - falling from an aeroplane, presumably at some significant height - on its entry to the pool it does not cause any water to splash out of the pool altogether, which it almost certainly would; and it would surely destroy any toy boat onto which it fell, given the terminal velocity it would attain along with its mass!
what allows aluminum boats to float?
The boats displace water in such a way that they remain afloat. Hence why most boats have a V hull shape. This allows them to displace the water and remain afloat, if on the other hand you put to much in a boat it will eventually sink.
Does the shape of the boat make it float?
The shape of the boat only affects how much energy is needed to move it (overcome friction) when floating on water. The boat has to have a high-enough profile so that when it is placed in water, it will not take on water. The amount of water displaced by the boat counteracts the weight of the boat exactly. When a 200-pound person steps into the boat, the boat will sink to displace an extra amount of water, the weight of which equal to 200 lbs. That is assuming the boat has not sunk yet.
What is the formula to calculate how many people can be on a boat?
No simple formula. When you add 100 kg to the boat, it displaces 100kg, ~ 100l water. You must then calculate how much lower the boat gets in the water, to displace that water. It would be easier, if the boat had vertical sides, like a barrel or a box, otherwise you need to do integration (calculus). If the boat is not rocking, and the water is perfectly still, you can put people into the boat, until the weight of the people equals the weight of the water displaced when the edge of the boat is at the edge of the water. But in real life, you must account for waves, wind etc. Then there is seating capacity, toilets, food etc, if we are talking about a liner or ferry.
How much water does a cubic foot of stryrofoam displace?
7.48 gals water
How do you calculate fiberglass boat weight?
It would be much easier to determine the weight of the water it displaces, if you are unable to place the boat on a scale. Place the boat in the water, mark the water line on the hull. Remove the boat from the water and measure the dimensions or volume of the hull below the water line. then multiply this dimension by the density of water, 62.4 lbs/ cu. ft. (or 1 Kg/dM). The result will be the empty weight of your boat. for instance a flat bottomed boat, 18 ft long, with a 6 foot beam, drafting 4 inches will displace approximately 36 cu. ft. of water this corresponds to a weight of 2220 lbs.
How much water would a 13cm by 10cm by 8cm object displace?
An object would displace an amount of water equal to its volume. The volume of the object is given by the product of its height, length, and width. V = l*h*w V = 13cm*10cm*8cm = 1040cm3
How the airplane float?
The same way anything floats, by displacing an amount of water that weighs as much as it does. Airplanes that are meant to float on water typically either have boat-like hulls or floats whose purpose is to displace enough water to allow the airplane to float.
Why do ships float when they are denser than water?
Quick and dirty answer: Because they are built to be essentially hollow, they are much larger in volume than the water they displace, and so in effect they are much less dense over all than the water they displace.
