What happens when you place an object in the water that has exactly the same density as water?
It will stay at whatever depth you place it ... 6 inches deep, 6 feet deep, at the bottom, etc.
If its density is exactly the same as the water's, then the buoyant force on it is
exactly the same as its weight. The force of gravity is exactly balanced by the
buoyant force, and the object is perfectly weightless in the water. Since the net
vertical force on it is zero, it has no desire to rise or sink, and it stays wherever
you put it.
This situation is called "neutral buoyancy". It's the condition submarines like to achieve
for submerged level cruising, by properly manipulating their ballast, so that they don't
have to constantly be fighting a tendency to rise or sink as they 'steam' along underwater.
If you place the object on the surface it will sink until it is just below the surface. At that point there is no net force on the object, but because it was moving when the force became zero it will continue to move down at constant speed, so it will slowly sink. If, however, you place the object anywhere under the water, at rest, it will stay where you place it because, again, there will be no net force on it.

What is an object that is equivalent to the density of water?
An object that is equivalent to the density of water is an object that has a density of 1 gram per cubic centimeter. This means that the object will have the same mass per unit volume as water. Therefore, if you were to place this object in water, it would neither sink nor float, but would stay suspended in the water.
How much does the density have to be for something to sink?
Answer: More than 1.0 Answer: More than the density of the liquid in which the object is placed. For example, water has a density of about 1000 kg/m3; any object with a greater density than this will sink if placed in water. If you place something in oil, the numbers are different.
Can you use mass alone to predict whether an object will sink or float?
No, you cannot use mass alone to predict whether an object will sink or float. The density of the object relative to the density of the fluid it is placed in also plays a crucial role in determining whether an object will sink or float. Objects with a density greater than the fluid will sink, while objects with a density less than the fluid will float.
How does the density of a rock affect its ability to float?
If the density of ANY object is less than 1.00, then it will float in fresh water. If the density is greater than 1.00, the object will sink in fresh water. If the object's density is precisely 1.00, it will be "neutrally buoyant" and will neither rise nor sink; it will remain at whatever depth you place it.
What are two ways you can change the buoyant force on an object?
-- Make the object bigger, by inflating it, or by beating it thin and forming it into a hollow box or ball. -- Place it in a fluid that has greater density than the fluid it's in now.
What will happen if an object's density is greater then a liquid's density?
If you place the object into the liquid it will sink.
Does density of an object change from place to place?
Of course not.
Why does a coin sink and a boat float?
An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.An object will sink if it has greater density than water (or whatever liquid it is place in); it will float if it has less density than the liquid.
What happens when you place a metal object in a outlet?
You will be electrocuted.

What happens to an object when balanced forces ac on it?
It will not move from it's place

If you place a less dense substance into another substance with a greater density what happens?
It floats.
What happens to an object that has large mass and little volume when place in watar?
It will get wet.
What experimental method can determine the density of metal?
Density is the mass of the object divided by its volume. By this principle, to determine the density of a metal, place the metal onto a scale to measure its mass. After this, place the metal into a beaker of water and measure the volume change in the beaker. Divide the mass by the volume and you get the density.
