What else can I help you with?
Why is it easier to lift an object underwater than it is to lift an object on land?
It is easier to lift an object underwater because the buoyant force exerted by the water helps support the weight of the object. On land, you have to lift the object against the force of gravity without any additional support.
If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater true or false?
It's true that the volume of displaced water of a floating object equalst the portion of that object that is underwater.
What is an underwater salvage?
a object found under water of value
Does a floating object weigh more when underwater?
No, a floating object displaces its weight in water, creating an upward buoyant force equal to the weight of the water displaced. Therefore, the object weighs the same whether it is floating on the surface or submerged underwater.
Is it true that If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater?
the weight of the displaced water is equal to the weight of the object
Does the force of gravity on an object differ from above and below water?
No. The mutual forces of gravity between the Earth and an object are exactly the same when the object is underwater as they are when it's above water. But when the object is underwater, there's an upward buoyant force on it, which compensates and cancels some or all of the gravitational force.
Why does an object feel lighter underwater than when its in the air?
An object feels lighter underwater because of the buoyant force exerted on it by the water. This force counteracts the gravitational force acting on the object, making it feel lighter.
Why it is easy to lift an object inside the water?
It is easier to lift an object inside water because water exerts an upward buoyant force on the object which counteracts the force of gravity pulling the object downwards. This makes the object feel lighter and easier to lift compared to in air.
Why can I see underwater without glasses?
When you are underwater, the water helps to refract light in a way that can improve your vision, making it easier to see without glasses.
How does the sound of an object change when it is underwater, is it louder or softer compared to when it is in the air?
When an object is underwater, the sound it produces is louder compared to when it is in the air. This is because sound travels faster and more efficiently in water than in air, resulting in a louder sound underwater.
If an object floats the volume of displaced water is equal to the volume of what?
Look at the LAST WORD of the question, they switch it sometimes if it is: Underwater than it is TRUE, If it's Surface of the water than it is FALSE ~
Explain why an object under water feels lighter when its in the air?
When an object is underwater, it displaces an amount of water equal to its weight. This buoyant force pushes the object upward, effectively reducing its weight. When the object is above the water, it is no longer displacing water, so the buoyant force is removed, making it feel heavier.
