It would have to be heavier than the amount of liquid that it displaces.
maybe the density of the objects
The salt makes the water dense and the object must be heavier like metal or a ship to sink.
It's weight. The general rule is that an object will sink if it has a density greater than the liquid in which it is placed.
An object will sink in water if its density is greater than the density of water. This means that the weight of the object is greater than the buoyant force acting on it. Consequently, the object displaces less water than its weight.
The earth's gravitational pull makes objects sink in a liquid, but buoyancy acts in the opposite direction to oppose the gravity. Whether an object sinks or floats depends on which force is bigger. ================================
Objects sink when their density is greater than the density of the fluid they are in. This causes them to displace a volume of fluid that weighs less than the object itself, leading to the object sinking due to the force of gravity.
why does an object sink
the buoyant force acts in the direction opposite to the force of gravity, so it makes the object feel lighter
The density of an object compared to the density of water determines whether it will float or sink. An object with a higher density than water will sink, while an object with a lower density will float. Mass does play a role in determining density but is not the sole factor in whether something floats or sinks.
It depends on the boyancy of the material and the location of the holes. A ship holed below the waterline will sink. A body board with holes in will float.
the salt water is denser because of the salt
Buoyancy, which is an upward acting force exerted by a fluid , that opposes an object's weight.
