Web31 okt. 2006 · Oct 31, 2006. #1. Ok. Hopefully this doesnt sound stupid. :blinking: From what I know, buoyancy is affected by the volume of water displaced by the size of the diver in water despite their weight i.e. the bigger the diver is, the more buoyant. However, fat is a relatively less dense tissue than muscle, which again will increase buoyancy. Web30 jul. 2024 · If a body stays on the surface of the water for a long time then it will release the gas that been built up and then it will sink into the water once again. Decomposition continues underwater and then more and more gas is collected and the body may start floating again.

Web30 mei 2024 · Buoyancy or upthrust is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. It is also said to be the force that causes objects to float. Buoyancy occurs when the differences in pressure acting on opposite sides of an object immersed in a static fluid. Web15 mrt. 2024 · Buoyancy is the ability of an object to float in a liquid. The relation of the object's weight to the weight of the water displaced is what determines if the object will float; although the size and shape of the object do have an effect, they are not the primary reason why an object floats or sinks.

Instead, it supports those seven to 12 pounds, with a few pounds to spare. Why does body smell after death? WebPeople often forget that the volume in the buoyancy formula refers to the volume of the displaced fluid (or submerged volume of the object), and not necessarily the entire volume of the object. Sometimes people think the buoyant force increases as an object is brought to deeper and deeper depths in a fluid.
