What can you tell about two objects if one floats and one sinks?

First, buoyancy force must be defined. A force is just a fancy way of saying weight. But, the buoyancy force of an object is an upward acting force on an object in fluid (water in my example) and is equivalent to the weight of the volume of water that the object sitting in the water displaces. So, boats displace a huge volume of water and thus their buoyancy force, which is acting upwards, is very large; so, a boat will float. So, if two objects that displace amounts of water equal to their volume (think 2 blocks of substances) are put into water, and one sinks while the other floats, then the one which sank has a higher density than water and the one which floated has a lower density than water. But, if one object was shaped like a bowl and was floating, then all you can say is that it has a greater buoyancy force than the other object which sank. Note that when an object sinks, it still has a buoyancy force, but this force is not as large as the weight of the object itself, which is acting downwards, overcoming the buoyancy force. This topic gets even more confusing when talking about foams of various geometries, but I hope what I said kind of helps.

What objects weigh one gram?
one dollar
One can use two-dimensional objects to build three-dimensional objects.?
Only if you have two dimensional objects of specific sizes in specific combinations.
Fill in the blank Points are -dimensional objects?
Zero. Points are zero dimensional objects. Straight lines are one dimensional objects. Planes and surfaces are two dimensional objects. Volumes and polyhedra are examples of three dimensional objects.
What is one of 3 identical objects?
A triplet.
What objects measure one kilometer?
Roads
Which one has more density the one that floats or sinks?
sinks
Soap or styrofoam which one floats?
Styrofoam floats on water, Soap sinks.
How do you make sure you purchase fresh eggs?
You can tell if eggs are old by dropping one in a cup or bowl of water. If the egg floats, it is bad. If it sinks, it is good.
Two objects have the same mass one floats one sinks which one has the greater mass?
The object that sinks has greater mass because it is denser. Density is a measure of how tightly packed the material in an object is. If an object is denser than water, it will sink; if it is less dense, it will float.
What happens to water level when something sinks or floats?
A floating object always displaces an amount of water of the same weight of the object. An object that sinks displaces the amount of fluid equal to the objects volume. Water levels rise. So to calculate either, you would need to know the weight or the volume. One other comment, the amounts are different between objects in fresh water and objects in salt water
Does mass determine an object will float or sink?
No. A toothpick and a tiny stone both have small mass, but one floats and the other sinks. A passenger ferry and a large boulder both have large mass, but one floats and the other sinks. It's not the mass that determines whether the object will float. It's the ratio of its mass to its volume ... the number known as the object's "density".
If two objects have the same volume and one of these objects sinks in water can you tell if the other object will sink as well?
Volume is the amount of area an object takes up. If their volumes are equal, their mass (weight) can be different or the same, so you can't always be sure.
How can you tell if one liquid is more dense than another?
You can tell if one liquid is more dense than another by comparing their densities. The denser liquid will have a greater mass per unit volume than the less dense liquid. One common way to compare densities is by observing which liquid sinks and which floats when they are layered on top of each other in a container.

Why would one rock float while one sinks?
The rock that sinks has a higher density than the rock that floats. (The only rock that floats is pumice.) More specifically, for a rock to float it must have a lower density than the fluid it is placed in. This will mean that a given volume of the material will have a smaller mass (and hence weight) than the fluid it displaces. As such the material will have positive bouyancy and will tend to float on top of the more dense material.
What is the difference between steam and a gas?
one floats one sinks. ive also heard that gas is more flirtatious. hope i helped u with your homework. i had the same question when i was a lad.... back in the day eh... w
What is a procedure for sink and float?
The one which flow has less density than the water (i.e. 1) means no screws will be there and they will be stuck with some adhesive.The one which sinks has more density than water and screws might be used in it because screws are generally made from iron whose density is more than that of water.
