Because the water or what ever it is cant stand the weight so it sinks
Yes it is a pseudoplastic, as stress is applied to it, it becomes more viscous, causing the person walking on it to sink. The more they struggle, the more stress is applied to it, the faster they sink.
Not all heavy things sink. Things that are more dense than the liquid around them will sink.
An object will sink if it has a greater density than water. In this case, the weight of the water displaced by the object is less than the weight of the object.
Lead weight, a stone, the list is endless.
things that are more dense sink while things that are less dense float
Things that float in a fluid are less dense than the fluid. Things that sink in a fluid are more dense than the fluid.
Things will sink if they are denser than water.
If their density, or weight per unit volume, is greater than that of the fluid density, they will sink
denser things sink faster the denser it is then the faster it will sink
The snow is soft and our weight is concentrating on our feet so there is more pressure hense our feet sink in snow
marble because it weight is more
In most cases the wood will float (there are a few dense tropical woods that will not) and the metal will sink. things float because they displace more weight of water than their own volume if not they sink
