The density of a domino can vary depending on its composition, but typically it falls within the range of 1.3 to 2.0 grams per cubic centimeter. This value is calculated by dividing the mass of the domino by its volume. The density of a domino is an important physical property that can affect its overall weight and stability.

The density of a domino can vary depending on the material it is made from. Typically, a wooden domino has a density of around 0.6-0.9 g/cm^3, while a plastic domino has a density of around 1.0-1.4 g/cm^3.
That would depend on what it is made of. If wood, about .8, but plastic that resembles ivory would be more.
A domino sinks in salt water because the salt water is denser than fresh water, providing more buoyant force to support the weight of the domino. The increased density of salt water makes it harder for objects to float on its surface compared to fresh water.
The input force on a domino is typically applied at the top of the domino by tipping it over. This force initiates the chain reaction by causing the domino to fall and push the next domino in line.
Inertia is involved in the falling of dominoes because once the first domino is pushed, it transfers its momentum to the next domino, causing a chain reaction. The inertia of each domino keeps it moving until it comes into contact with the next domino, continuing the process.
The weight of one standard domino is approximately 8 grams. This weight can vary slightly depending on the material the domino is made of, but in general, a standard plastic or wooden domino weighs around 8 grams. This weight is commonly used in calculations and experiments involving dominoes.
The source of energy that made the first domino move was external force or mechanical energy. It could have been from a person, a machine, or any other object that initiated the motion by applying a force to the first domino.
