What else can I help you with?
Is wood harder than rubber?
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.
Can paper cut metal?
No, paper cannot cut metal. Metal is much stronger and harder than paper, so paper would not be able to cut through it.
Which has more inertia-a cricket ball or a rubber ball?
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.
Does a rubber band break or rip?
A rubber band can break when stretched beyond its limits, rather than ripping like paper. The material weakens and eventually snaps due to the stress placed on it.
How does rubber erase pencil marks?
Rubber is able to erase pencil marks because it has a sticky and abrasive surface that lifts and removes the graphite from the paper. When rubbed against the paper, the friction created by the rubber loosens the graphite particles, allowing them to stick to the rubber and be wiped away.
Is chalk harder than rubber?
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.
Is wood harder than rubber?
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.

Why are rubbers made of rubber and can rub out and rubber balls cannot?
Rubber as a compound can be formulated in many ways. In erasers it is made to be stickier to graphite particles from lead pencils than paper so the graphite preferentially sticks to the eraser. The rubber is also soft so the paper abrades it and the graphite containing surface os worn away for disposal. The result is clean paper and rubber/graphite dust. Some very soft erasers for art work are very soft so that no danmage to the paper happens, These can retain the graphite and eventually get quite dirty and have to be discarded as they leave maks rather than remove them. Some erasers contain a bit of abrasive and remove the top layer of the paper as well making them useful for removing inks that penetrate the paper surface. A rubber ball is generally made from a harder and tougher rubber without the stickiness or softness of the eraser. Most modern "rubber" balls are made of chemical polymers which are not really rubber and have to affinity for graphite.
Is birch or rubber harder?
Birch is much harder.
Is plastic harder than rubber?
Yes! Depends which plastic and which rubber you are talking about. It really is quite alarming how people use terms like "Plastic" and "rubber" when there are HUGE numbers of massively different products falling under each category. You wouldn't say "Come round for dinner tonight, we're having 'food' followed by 'food' and then some 'food' for dessert" would you??
Can paper cut metal?
No, paper cannot cut metal. Metal is much stronger and harder than paper, so paper would not be able to cut through it.
Is bitumen a metal?
no, its like rubber but harder
Why are trees harder than paper?
oh i don't know why trees are harder then paper but trees are very solid and 10 feet tall and not thin at all... and not treated jeesh to they teach people stuff these days?
Is pure gold harder than a paperclip?
No, pure gold is softer than a paperclip. Gold is a malleable metal, which means it can be easily molded and bent by applying pressure. A paperclip is made of steel, which is much harder than gold.
Which has more inertia-a cricket ball or a rubber ball?
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.
Charles Goodyear has a patent on doing what to rubber?
vulcanizing rubber. :) i had to do a paper on him
