Admin Which block has the greater buoyant force?
lead block
The lead block. The buoyant force equals the weight of the displaced fluid, so the lead block experiences the largest buoyant force.
Which object has the greatest buoyant force on it?
So, the volume of fluid displaced equals the volume of the object in each case, meaning that whichever object has the largest volume will experience the greatest buoyant force. Since aluminum has the largest volume, and the largest volume of water displaced, it experiences the greatest buoyant force.
What is the buoyant force on the block?
Abstract. I propose that buoyant force be generally defined as the negative of the total weight of the fluids that are displaced, rather than as the net force exerted by fluid pressures on the surface of an object. In the case of a body fully surrounded by fluids, these two definitions are equivalent.
Is the buoyant force on the lead block greater than less than or equal to the buoyant force on the aluminum block choose the best explanation?
For objects that are completely submerged the buoyant force is proportional to the density of the object. Since the two blocks are the same size (volume), then the buoyant force on the lead block is greater than the buoyant force on the aluminum block.
Is the buoyant force acting on the block greater than less than or equal to the weight of the block explain?
If the buoyant force is greater than the object’s weight, the object rises to the surface and floats. If the buoyant force is less than the object’s weight, the object sinks. If the buoyant force equals the object’s weight, the object can remain suspended at its present depth.
What is the buoyant force on the block and why does it float?
Any object that is in water has some buoyant force pushing up against gravity, which means that any object in water loses some weight. If the object displaces an amount of water equal to its own weight, the buoyant force acting on it will be equal to gravity—and the object will float.
