Yes, wood is harder than rubber. Wood is a natural material known for its density and durability, while rubber is a synthetic material that is much softer and more elastic in comparison.
No, paper is typically softer than rubber. Rubber is a solid material known for its flexibility and elasticity, while paper is a lightweight material made from compressed fibers that is more brittle and easier to tear.
Rubber is a better insulator than wood. Rubber contains a higher concentration of insulating properties, such as resistance to electricity and heat transfer, making it more effective in blocking the flow of energy compared to wood.
The coefficient of friction between wet wood and rubber can vary depending on the specific types of wood and rubber involved, as well as the amount of moisture present. Generally, the coefficient of friction between wet wood and rubber is lower than that between dry wood and rubber due to the reduced frictional forces caused by the presence of water. Experimentation or testing may be necessary to determine the specific coefficient of friction in a given scenario.
The cricket ball has more inertia than the rubber ball because inertia is directly proportional to mass. The cricket ball is denser and heavier than the rubber ball, making it harder to change its state of motion.
The coefficient of static friction for wood on rubber can vary depending on the specific materials, surface conditions, and other factors. However, on average, the coefficient of static friction for wood on rubber is typically around 0.6 to 0.8.
Maple wood is generally harder than oak wood.
Chalk is harder than rubber. Chalk is a form of limestone made of calcium carbonate, which is a relatively hard mineral, whereas rubber is a soft and flexible material typically made from natural or synthetic polymers.
Yes
It can be and can't be. It really depends on what sort of wood.

No
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
No, paper is typically softer than rubber. Rubber is a solid material known for its flexibility and elasticity, while paper is a lightweight material made from compressed fibers that is more brittle and easier to tear.
No, generally graphite is softer than wood. Wood is composed of cellulose fibers and lignin that can make it harder than the carbon atoms in graphite, which are arranged in layers that can easily slide past each other.
Oak is generally considered to be harder than maple.
One is sharper than the other. Like metal is harder than wood so the mettal one has to be harder.
Rubber is a better insulator than wood. Rubber contains a higher concentration of insulating properties, such as resistance to electricity and heat transfer, making it more effective in blocking the flow of energy compared to wood.
