Three characteristics that are unique to mammals include their  ability to feed their babies with milk made in their mammary  glands. Mammals also have hair on their bodies â¦and they have a  single bone that makes up their lower jaw.
buoyancy. n. 1. the ability to float in a liquid or to rise in a fluid. 2. (General Physics) the property of a fluid to exert an upward force (upthrust) on a body that is wholly or partly submerged in it. 3. the ability to recover quickly after setbacks; resilience.
Introduction to upthrust physics: Definition of upthrust: The upward force exerted by any fluid on an object placed in is called Upthrust. This is known as buoyant force also. To understand this concept better let us discuss some more details about it.I like to share this Static Friction Formula with you all through my article.hat is â. The upthrust on a body immersed in a fluid is equal to the weight of the fluid displaces by it. We have to derive upthrust or buoyant force to prove Archemedesâ Principle. image of upthrust. A cube A is immerged into a beaker filled with a liquid.
