When a body is partially or fully immersed in a fluid it experiences a buoyant force from where this force come?

The buoyant force comes from the pressure difference between the top and bottom of the immersed body. The fluid exerts more pressure at the bottom of the body compared to the top, pushing it upwards. This force is equal to the weight of the fluid displaced by the body, known as Archimedes' principle.

Water within cells is called?

There's no name for such a fluid, because the body can't 'produce' water. No water that didn't go into the body earlier can come out of it.


What causes the fluid to come out the top of the tube?

The fluid comes out of the top of the tube due to a combination of pressure differences and gravitational forces. When the pressure inside the tube is higher than the atmospheric pressure outside, it forces the fluid upward. Additionally, if the tube is tilted or if a vacuum is created, this can further facilitate the movement of fluid to the top. If the fluid is under tension or if an external force is applied, it can also contribute to the fluid being expelled.


Where does extracellular fluid content come from?

Why would trans fluid come out breather on a Ford Aspire?

Trans fluid may come out of the breather on a Ford Aspire due to overfilling of the transmission, which can cause excess pressure and force fluid out of the breather. Additionally, a malfunctioning transmission vent or a clogged vent line can lead to improper pressure regulation, resulting in fluid leakage. It's also possible that internal transmission issues, such as faulty seals or gaskets, could cause fluid to escape. Regular maintenance and checking fluid levels can help prevent this issue.
