Answer:
It will keep floating on the surface with a part of the body inside the liquid and a part outside it.
Explanation:
The Archimedes principle is the physical principle that states: a body totally or partially submerged in a fluid at rest, experiences an upward vertical thrust equal to the weight of the volume of fluid dislodged by the body. This force 1 is called hydrostatic thrust or Archimedes, and is measured in Newtons (in the SI). The Archimedes principle is formulated as follows:
flotation force = liquid density × force of gravity × volume of liquid dislodged
Therefore in this case when placing a body in water whose weight is equal to the buoyant force, it will float in equilibrium on the surface of the liquid, since the volume of liquid that it displaces is equal to the weight of the body and this force of below upwards it keeps it on the surface with a part of the body inside the liquid and a force part of it. This is because only the volume of the necessary object is submerged to move the liquid corresponding to a buoyant force equal to its own weight.
Answer:
A
Explanation:
option A is correct
the best example of elastic collision among the following is collision between two billiard balls. In collision of two billiard balls the energy lost is very little approximately zero. hence we can say that the kinetic energy is conserved. since, the kinetic energy is conserved we can say that the collision is elastic
Answer:
I believe it is A. The human body would not function normally without essential body fat.
Explanation:
The Olympic sport of curling is one that is practically designed to show Physics in motion. Curling is a sport in which two teams alternate sliding smoothed stone pucks down an ice rink court with the intent to seat their stone closest to the center of the target (called the house). Each team has eight stones, meaning that the team that goes second has the (could be) massive advantage of sending the last stone.
The mass of the stone is important in that the more massive a stone (m) and the speed at which it travels (v) dictates it's momentum (momentum=mxv). As the curling stone slides down the ice (which is relatively frictionless unless acted upon by other players or objects) and having inertia, continues in it's straight course (again, unless acted upon by outside forces). If the stone hits another stone, it transfers some of its momentum in an elastic collision to that stone and the original stone is deflected in a calculable manner.
Collisions are used in the game to either clear opponent's stones from the house or out of their defensive positions, or to make adjustments to one's stones present in the house, all based on the momentum of the moving stone, and its transference.
Answer:
Boyle’s law and,Charles’s law
Explanation:
For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.
