The average density of an object determines its buoyancy. If the average density of an object is less than the density of the fluid it is in, it will float. If the average density is greater, it will sink. Buoyancy relies on the difference in densities between the object and the fluid.
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.
Salt water is denser than fresh water. Since the buoyant force is equal to the weight of the displaced liquid or gas, an object of a certain volume will have more buoyant force pushing it up in salt water than in fresh water. It's sort of the same reason we can float on water but not in the air. Air is so much less dense than water that to float in it we need to displace a volume of it equal to the volume of a hot air balloon.
Density is mass/volume. So for a given mass as the volume increases the density will reduce.
yes
Volume affects buoyancy by influencing the amount of water displaced by an object. An object with a greater volume will displace more water, creating an upward buoyant force. This force helps to counteract the force of gravity acting on the object, allowing it to float or be less heavy in water.
Buoyancy is not constant regardless of the shape of the container. It depends on the volume of liquid displaced by the object, as described by Archimedes' principle. The shape of the container can affect the volume of liquid displaced and therefore impact the buoyant force acting on an object.
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
underwater your lung become a balloon and as much air it hold as much positive buoyancy effect it makes. We are using our lung underwater to maintain our buoyancy. That is why you should follow the rule of "Never Hold a breath" as if you did and assented fast your can damage your lung
The volume of the displaced fluid is the most significant factor influencing buoyancy force. This is because buoyancy force is directly proportional to the volume of fluid displaced by an object.
The buoyancy force on an object submerged in water is determined by its volume. The greater the volume of the object, the greater the buoyancy force it will experience. This is because buoyancy force is equal to the weight of the water displaced by the object, and volume directly affects the amount of water displaced.

It depends on the objects' volume. Different objects that have the same volume, if submerged, experience the same buoyancy. The buoyancy is equal to the weight of the displaced liquit; in other words, volume (of submerged object, or of the submerged part) x density of the liquid x gravity.
Yes, the volume of an object can affect whether it will sink or float. In general, an object with a greater volume will have greater buoyancy, making it more likely to float in a fluid. However, other factors such as density and the density of the fluid will also play a role in determining whether an object will sink or float.
Negative buoyancy can be influenced by factors such as body composition (muscle is denser than fat), bone density, and lung volume. Some individuals may have negative buoyancy due to having higher muscle mass, lower body fat percentage, or denser bones, making them less buoyant in water. Additionally, some medical conditions or injuries can also affect a person's buoyancy.
Reserve buoyancy is the watertight volume a ship has above the waterline.Buoyancy is the upward force on a ship derived from the displacement of a weight of water equal to the weight of the ship (produced by watertight volume below the waterline).
