Light bends as it passes from the water to the air - this changes the perspective of where the object is.
It depends on the density of the object that weighs one pound, and how much of it is under water. The object will weight 1lb - water density * object volume under water; If the object is on average is less dense the water (i.e. is buoyant), and is allowed to swim, its weight will be 0 because proportion of its volume under water will compensate gravity exactly.
Water resistant is not the same thing as water proof. A water resistant object can get wet and not be damaged, but it should not actually be submerged entirely. It still has some degree of vulnerability to water.
To calculate the weight of an object under water, you can use the equation: Weight (in water) = Weight (in air) - Buoyant force. The buoyant force is equal to the weight of the water displaced by the object. By subtracting the buoyant force from the weight in air, you can find the weight of the object in water.
Crocodiles close there valve to stay under water.
a object found under water of value
Because - light reflecting back to the observer from the object is bent as it leaves the water. This makes the object appear to be in a different place to where it actually is.
The first object to be seen under the microscope is believed to be a simple microorganism called a tardigrade or a water bear. These tiny, resilient creatures are found in water and are commonly used in scientific research.
To go under water they close their ears and nostrils. An adult hippo can stay under water for up to 6 minutes!
My foot is actually about 1 foot long!
The buoyant force on a floating object is equal to the weight of the water it displaces. This is known as Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by an object.
A heavy object feels lighter in water because the upward buoyant force exerted by the water opposes the force of gravity acting on the object. This buoyant force counteracts the weight of the object, making it feel lighter.
