Example 1: If a block of solid stone weighs 3 kilograms on dry land and 2 kilogram when immersed in a tub of water, then it has displaced 1 kilogram of water. Since 1 liter of water weighs 1 kilogram (at 4 °C), it follows that the volume of the block is 1 liter and the density (mass/volume) of the stone is 3 kilograms/liter.
The weight of the object in the fluid is reduced, because of the force acting on it, which is called upthrust. In simple terms, the principle states that the buoyant force (F b) on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume (V) times the gravity (g) [1] [3]

In physics, apparent weight is a property of objects that corresponds to how heavy an object appears to be. The apparent weight of an object will differ from the ordinary weight of an object whenever the force of gravity acting on the object is not balanced by an equal but opposite contact force. By definition, the weight of an object is equal ...
"The majority of the adult body is water, up to 60% of your weight," says Schnoll-Sussman, adding that the average person's weight can fluctuate one to five pounds per day due to water.
The Little Professor is a backwards-functioning calculator designed for children ages 5 to 9. Instead of providing the answer to a mathematical expression entered by the user, it generates unsolved expressions and prompts the user for the answer.
Formula weight calculator: The input is a chemical molecular formula, using the periodic-table symbols and notation, and there is a button to work out the percentages of its constituents. Astronomical calculator : The input is a date and one or multiple celestial bodies (usually the sun, moon, planets, planetoids or comets).
Tiger Electronics has been part of the Hasbro toy company since 1998. [8] [9] Hasbro paid approximately $335 million for the acquisition. [10]In 2000, Tiger was licensed to provide a variety of electronics with the Yahoo! brand name, including digital cameras, webcams, and a "Hits Downloader" that made music from the Internet (mp3s, etc.) accessible through Tiger's assorted "HitClips" players ...
