A floater is an object that has a lower density than the fluid it is in, allowing it to remain on the surface or float. In contrast, a sinker has a higher density than the fluid, causing it to sink. This principle is governed by Archimedes' principle, which states that an object will float or sink based on the relationship between its density and the density of the fluid.

Why is there need to dry the sinker before using it?

Drying the sinker before using it helps to remove any moisture or contaminants that might affect the accuracy of the measuring scale. Moisture can add weight to the sinker, leading to incorrect measurements. Therefore, ensuring the sinker is dry helps to maintain the precision of the measurement process.


Which solar system object is most similar to Earth's in terms of mass and density?

Venus is the most similar solar system object to Earth in terms of mass and density. Venus has a mass of about 81.5% that of Earth and a density of about 94.5% that of Earth.


Why is a sinker necessary in determining the lifting effect of water?

A sinker is necessary to determine the lifting effect of water because it helps to counteract the buoyant force exerted by the water on the object. By adding a sinker, you can measure the force required to keep the object submerged, which allows you to calculate the buoyant force acting on the object.


Can you fill floater with air?

Yes, you can fill a floater with air, as many floaters, such as inflatable pool toys or beach floaties, are designed to be inflated. Using a pump or your breath, you can fill them with air to achieve their intended buoyancy. However, always ensure that the floater is properly sealed and in good condition to prevent air leaks.


What solar system objects is most similar to Earth in terms of mass and density?

Venus is the solar system object most similar to Earth in terms of mass and density. Venus is similar in size and composition to Earth, making it the closest "sibling" planet to our own.
