What is the force of gravity acting on the block (the weight) in water?
The force of gravity on a block is the same, whether it is in air or in the water. The apparent weight (the force you need to keep it from falling) is less in water, due to the buoyancy force, which counteracts the weight.
How much does a stone weight in salt water?
Correct formulation: "How much does a stone weigh in salt water?"Answer: The same as it does in the air, water, anywhere.
I've starved myself for 7 days living only on water how much weight can you lose?
you wont lose weight you may even put more on due to starvation
Which thing drop in water their weight increase doubled and doughted then their weight increase triple?
The solution for this riddle is salt. When salt is dropped in water, its weight doubles due to water absorption. If you then add more salt, making it saturated, the weight will triple due to full saturation with water.
How much water does it take to move a building?
The building would float when the water weight being displaced equaled the weight of the house, but the house may move due to absorption of the water's kinetic energy before it floated. A river or flood for instance.
How do you calculate weight in air when we know weight in water and water displaced?
To calculate weight in air when we know weight in water and water displaced, you can use the principle of buoyancy. First, subtract the weight in water from the true weight to find the buoyant force acting on the object. Then, divide the buoyant force by the acceleration due to gravity to get the volume of water displaced. Finally, use this volume to find the weight of the object in air by multiplying it by the density of water and acceleration due to gravity.
What is the weight of water displaced in a massless balloon?
The weight of water displaced in a massless balloon is equal to the weight of the water that the balloon displaces. This is determined by the volume of water displaced and its density, as weight is determined by the mass of the water and the acceleration due to gravity.
Why is the weight of rock different in and out water?
The weight of a rock is less in water because water exerts an upward buoyant force on the rock, reducing its effective weight. This is due to the principle of buoyancy, where the weight of the water displaced by the rock counteracts the rock's weight.
What objects that do not experience much air or water resistance?
Objects in space, such as satellites or astronauts in orbit, do not experience much air or water resistance due to the lack of atmosphere or water in space. Additionally, very small objects like dust particles or certain microorganisms may not experience significant air or water resistance due to their size and weight.
What is the apparent weight for a body floating in water equal to?
The apparent weight of a body floating in water is equal to the weight of the water displaced by the body. This is known as Archimedes' principle. The apparent weight is less than the actual weight of the body due to the buoyant force acting on it.
How much does water pressure increases every meter?
Water pressure increases by 9.81 kilopascals (kPa) for every meter of depth due to the weight of the water column above. This principle is known as hydrostatic pressure.
Why does body loss weight in salt water?
The apparent weight will change, due to a stronger buoyant force by the salt water, which has greater density than normal water.
