why does a 5p sink but a heavier piece of wood floats?
help mee
cuz it has more upthust!
wat does that mean!!
It means whatever you want it to mean. You go ahead and decide.
The reason why a 5p coin sinks while a heavier piece of wood floats is due to the concept of density. Density is a measure of how much mass (or matter) is packed into a given volume. When comparing two objects of the same volume, the one with the higher density will sink, while the one with the lower density will float.
To understand this better, let's compare the densities of a 5p coin and a piece of wood. The density of an object can be calculated by dividing its mass by its volume. In the case of the 5p coin, it is made of metal (typically copper-plated steel) and has a relatively high density. On the other hand, wood is less dense since it is composed mostly of air-filled cells, making it lighter.
To further illustrate this, you can conduct a simple experiment. First, weigh both the 5p coin and the piece of wood to determine their masses. Then, fill a container with water and carefully place each object into the water. Observe how they behave.
Because the density of the 5p coin is higher than that of water, it will sink. In contrast, the wood has a lower density than water, so it will float. This is because the buoyant force exerted by the water on the object is greater than the force of gravity pulling it downward, allowing it to float on the water's surface.
In summary, the reason a 5p coin sinks while a heavier piece of wood floats is due to the difference in density between the two objects. The higher density of the coin causes it to sink, while the lower density of the wood allows it to float.
