Question
The statement that the upward buoyant force that is
exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces is related to:Solution
Archimedes' principle states that: "The upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the volume of the fluid that the body displaces."
A boat takes 5 hours longer to travel 15 km upstream than it does to travel 20 km downstream. The speed of the boat in still water is 5 km/hr. Calculate...
