the buoyant force will remain the same because the rock will displace the same amount of water volume at any depth.
Theoretically, it will gain buoyancy as it sinks, because when an objects density matches the density of the water around it, and water becomes denser as it falls deeper, it will be neutrally buoyant or floating. But since a rock is always going to be more dense than water it would still sink.
as it sinks deeper into water the effective value of acceleraion due to gravity increases so the weight of the body will increase thereby resulting in an increase of buoyant force but if we assume the value of acceration due to gravity to be a constant than the force remains same.
The buoyant force is zero when the object is just touching the liquid. As the object displaces more volume, the buoyant force increases until the object is completely submerged. Once the object is submerged, it doesn't matter how deep it is, the buoyant force remains constant.
No.
float in the fluid
the buoyant force
If she is completely immersed, there would only be a change if the water changes density (unlikely) or she changes her volume (also unlikely) as the buoyancy force is the product of her volume under the water, the density of the fluid and gravitational acceleration. If none of those change, then the buoyancy force will not change.
Yes as long as it does not compress as it sinks further.
The heavier the boat is loaded, the deeper in the water the boat will float.
Increasing, because the volume of displaced fluid, and therefore the weight of displaced fluid, is increasing.
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.
Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.
A buoyant force equals the weight of the fluid being displaced
Buoyant force is directly proportional to the density of the liquid. as the density of the liquid increases, the Buoyant force increases.
No, the buoyant force comes from a pressure difference between the top and the bottom of the object. the deeper you go the larger the pressure gets, that means when you are under water there is more pressure pushing you up than down(more pressure at the bottom than top), making you feel liter. the buoyant force on the sides are both the same so they cancel each other out. also, the buoyant force is equal to the weight of the fluid displaced by the object.
The buoyant force depends on the volume of liquid displaced and the density of the liquid.
the 'buoyant' force
As buoyant force decreases then the body starts sinking down.
buoyant force = density of the liquid*Volume*gravity. so the buoyant force is directly proportional to the density of a liquid.
