The displaced water should also weigh 450 N.
?
They weigh less than the water they displace.
equal to their weight
A styrofoam cup will float in water because styrofoam is less dense than water, causing it to displace water and float.
Yes, a lemon will float on water due to its low density. The air pockets in the lemon's skin allow it to displace enough water to float.
Yes, less dense objects float in water because they are lighter than the water they displace.
Objects float on water when they displace an amount of water equal to their weight, creating an upward force called buoyancy that counteracts gravity. This buoyant force is greater than the weight of the object, allowing it to float. Objects like boats or ships are designed to displace enough water to keep them afloat.
If its average density is less that water, it will displace more than its own weight in water, and it will float.
Heavy objects generally sink when placed in water because the density of the object is greater than that of water, causing it to displace less water and sink. For an object to float, it must displace an amount of water equal to its own weight.
Yes, an object's shape can affect its ability to float. Objects with larger surface areas relative to their volume, like flat objects or objects with concave shapes, are more likely to float because they displace more water. Objects with irregular shapes or holes are less likely to float because they displace less water due to their shape.
The higher the salinity of the water, the greater the buoyant force exerted on the object, thus making it easier for objects to float. This is because saltwater is denser than freshwater, providing greater support to objects trying to float.
