8 A rock suspended by a scale weighs 5 N out of water and 3 N when submerged in water What is the buoyant force on the rock?
The buoyant force accounts for the missing 2 N when the rock is in water. The 2 N is the weight of the volume of water equal to the volume of the rock ... the water that the rock 'displaces' (pushes aside) when it enters the water.
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.
13A 1liter container filled with mercury has a mass of 13.6 kg and weighs 133 N when it submerged in water what is the buoyant force on it?
The buoyant force acting on the container filled with mercury is equal to the weight of the water displaced by the container. Given that the weight of the container when submerged in water is 133 N, this weight includes both the gravitational force and the buoyant force. To determine the buoyant force alone, subtract the gravitational force (13.6 kg * 9.8 m/s^2 ≈ 133.28 N) from the total weight: 133 N - 133.28 N ≈ -0.28 N, or essentially 0 N.
When an object is placed in a fluid the object weighs less by an amount equal to the weight of the dispaced fluid?
This phenomenon is known as buoyancy, which is a force exerted by a fluid that opposes the weight of an object immersed in it. The buoyant force is equal to the weight of the fluid displaced by the object. As a result, the object effectively weighs less when submerged in the fluid.
What is the buoyant force of an object that weighs 180 N and floats with three-fourths of its volume beneath the surface of the water?
The buoyant force is equal to the weight of the water displaced by the object. Since three-fourths of the object's volume is submerged, it displaces an amount of water equal to three-fourths of its volume. Therefore, the buoyant force is equal to three-fourths of the weight of the water displaced, which in this case is 180 N.
How great is the buoyant force on a balloon that weighs 1 N when it is suspended by buoyancy in air?
1 newton.

What if an objects weighs 135 newtons how much is the buoyant force to make a neutral buoyancy?
The buoyant force is 135N

What an object does if it weighs greater than the buoyant force?
If an object weighs more than the buoyant force acting on it, it will sink in a fluid such as water. The buoyant force is not enough to offset the weight of the object, so the object will continue to descend until it reaches the bottom of the fluid.
A balloon weighs 1N is suspended in the air drifting neither up nor down How much buoyant force acts on it?
The buoyant force acting on the balloon is equal to its weight, which is 1N. This is because the balloon is in equilibrium, with the buoyant force balancing the weight of the balloon, so it does not move up or down.
Does an objects buoyant and weight mean the same thing?
no because buoyant means how much can an object float and weight means how much it weighs.
What does weigh mean?
Hydrostatic weighing, also called underwater weighing, involves being weighed underwater.requires one to be completely submerged in water for a few seconds. ref. http://www.wisegeek.com/what-is-hydrostatic-weighing.htm
A girl is floating in a freshwater lake with her head just above the water If she weighs 510 N what is the volume of the submerged part of her body?
The buoyant force pushing her up in freshwater is equal to the weight of the water she displaces, which is 510 N. The volume of the submerged part of her body is equal to the volume of water that provides an upward force of 510 N.
