Oh, dude, the relative density of a rubber eraser is basically how much denser it is compared to water. So, if you drop a rubber eraser in water and it sinks, it's denser than water. If it floats, it's less dense. It's like a little science party in your pencil case, man.
An eraser sinks because it is denser than water. The density of an object determines whether it will float or sink in water. In the case of an eraser, its density is greater than that of water, so it sinks.
Rubber is an insulator, meaning it does not conduct electricity. Therefore, electricity cannot pass through a rubber eraser.
A magic one is an insulator.
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
An eraser typically sinks in water due to its density being higher than that of water.
To determine the density of a rubber eraser, you would first measure the mass of the eraser using a scale. Next, measure the volume of the eraser by submerging it in a graduated cylinder filled with water and recording the water displacement. Finally, divide the mass of the eraser by its volume to calculate the density.
No. It is "rubber" or a synthetic form of it. That is why it is called a rubber eraser and not a steel eraser.

An eraser erases things. A rubber rubs things out.
No, an eraser is made of rubber. Gallium is a metal.
