...well known to all my readers. This law says that " Every body which is immersed in a fluid loses a part of its weight, or is acted upon by an upward force equal to the weight of the displaced fluid." Hence a body will remain at rest in any position if immersed in a fluid of equal...

...(287-212 BC), and it is called the principle of Archimedes. It states that any body immersed in a fluid is acted upon by an upward force equal to the weight of the fluid displaced by it. A simple test of the law can be easily made if we have a sensitive balance weighing...

...that discovered by the Greek mathematician Archimedes. He found that an object submerged in a fluid is acted upon by an upward force equal to the weight of the fluid that the object displaces. The volume of fluid displaced by a submerged object is equal to the...
