What is the buoyant force acting on the rock when A rock with volume of 0.3m3 is fully submerged in water having a density of water is 1000 kgm3?

The buoyant force on a submerged object is equal to the weight of the displaced fluid. The density of the water is 1,000 kg/m3, so its weight is 1,000 N/m3. The volume of the rock is 0.3 m3. The buoyant force = weight of the displaced water = (0.3 x 1,000) = 300 N.

Mercury insert a bigger buoyant force to a fully submerged wood?
That is true. Because buoyant force is nothing but the weight of the displaced liquid when a body gets submerged in the medium of liquid. In case of mercury the relative density of mercury is 13.6 compared to that of water. A wood when placed in water, that would float due to greater buoyant force. If it is so, then you imagine about the buoyant force in case of submerging a wood in mercury. Wood having greater volume would expel that much volume of mercury. Hence the weight of the equally displaced mercury will be immense and so the result. Usually iron nails would float on mercury.
How can matter be more or less buoyant?
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.
What allows objects float up in the water?
Density water having a density of 1.00 anything .99 or below will float and anything above will sink same scenario for oxygen and gasses for example helium has a lighter density than oxygen and that's why helium filled balloons float
Which is the object having the highest density?
osmium has the highest density.
What does this word means buoyant?
buoy·ant (boi'ənt, bū'yənt)adj. # Having or marked by buoyancy: a buoyant balloon; buoyant spirits. # Lighthearted; gay: in a buoyant mood. [Spanish boyante, present participle of boyar, to refloat a boat, from boya, buoy, from Old French boue. See http://www.answers.com/topic/buoy?initiator=WANS.] buoyantly buoy'ant·ly adv.from answers.comIt means the ability to float. A balloon has buoyancy, a rock does not.
State having lowest density of population?
The moon has a remarkably low population density.
Why is Taylor lautner having so much trouble with his acting career?
This rumor is not true. His acting career is soaring. He is doing very well in his acting career.
How do you purify fuel oil having density more than one?
use centrifuge.. :)) How can you use centrifuge because sealing water density is 'One' and you will be feeding oil having density more than 'One'

Why a ship made up of a metal like steel floats on the sea but a piece of metal sinks when dropped into the sea?
Archimedes' principle, principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both floating and submerged bodies and to all fluids, i.e., liquids and gases. It explains not only the buoyancy of ships and other vessels in water but also the rise of a balloon in the air and the apparent loss of weight of objects underwater. In determining whether a given body will float in a given fluid, both weight and volume must be considered; that is, the relative density, or weight per unit of volume, of the body compared to the fluid determines the buoyant force. If the body is less dense than the fluid, it will float or, in the case of a balloon, it will rise. If the body is denser than the fluid, it will sink. Relative density also determines the proportion of a floating body that will be submerged in a fluid. If the body is two thirds as dense as the fluid, then two thirds of its volume will be submerged, displacing in the process a volume of fluid whose weight is equal to the entire weight of the body. In the case of a submerged body, the apparent weight of the body is equal to its weight in air less the weight of an equal volume of fluid. The fluid most often encountered in applications of Archimedes' principle is water, and the specific gravity of a substance is a convenient measure of its relative density compared to water. In calculating the buoyant force on a body, however, one must also take into account the shape and position of the body. A steel rowboat placed on end into the water will sink because the density of steel is much greater than that of water. However, in its normal, keel-down position, the effective volume of the boat includes all the air inside it, so that its average density is then less than that of water, and as a result it will float.
