What are hard non porous surfaces?
Anything surface that won't absorb liquid, i.e. tile, glass, stone, laminated, varnished wood. Bare, untreated wood would be considered a porous surface. hope this helps
Does aluminium absorbe sound?
This much depends on the properties of the plastic. Foam will reflect little and absorb much. Hard plastic will reflect much and absorb little. Soft plastic will absorb more than hard plastic and reflect more than foam. Regards.
Why is granite used to make kitchen work surfaces?
It takes a polish, is relatively impermeable, hard, and beautiful.
How do you prevent calluses on toes?
Calluses on toes are usually caused by ill-fitting shoes, walking on hard surfaces and having flat feet. To prevent calluses, one must purchase shoes that fit properly, avoid walking on hard, rough surfaces and seeing a doctor about flat feet.
Growth of a vine around a post is an example of a gravitropism or a thigmotropism?
i think thigmotropism, because thigmotropism is when tendrils of a plant grow on hard surfaces.
Why do balls bounce better on hard surfaces than soft ones?
Soft surfaces absorb quite a lot of the energy (by deforming) that the ball uses to spring back up, whereas hard surfaces don't absorb that energy (because they don't deform), and so the energy is used to deform the ball, which is then converted back into kinetic energy and the ball bounces.
What are hard surfaces?
A hard surface is one which does not yield when pressed. Wood, stone and glass are hard surfaces.... rubber, fabric and foam are soft surfaces.
Does friction depend on the types of surfaces involved and how hard the surfaces push together?
Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
Remove chewing gum from hard surfaces?
Peanut butter can be used to remove chewing gum from hard surfaces.
What factors determines the strength of the frictional force between two surfaces?
how hard the surfaces push to gether the types of surfaces involved
Why does a tennis ball bounce higher on harder surfaces?
Because the hard surface doesn't absorb any of the energy of the tennis ball - thus the ball bounces higher than if it was dropped on a softer surface.
What are the muscular tubes that stinging animals use to grip hard surfaces?
Most stingers are barbed, which allow them to grip to hard surfaces.
Friction depends on the types of surfaces involved and how hard the surfaces push together?
Yes.

Does walking on roads cause arthritis?
The risk of causing wear and tear injury's to joints is increased by spending a lot of time walking on flat hard surfaces like roads and concrete. There is also more risk of damage resulting from perfectly flat surfaces like carpet and floor boards. Hard surfaces have no give in them so the onus is on the cartilage and muscles around joints to absorb the the shock with every step taken. Walking on hard irregular surfaces will tend to help develop muscles around the joins involved which in turn helps to support that part of the joint that is covered with cartilage. The constant use of perfectly flat surfaces especially those that are hard and unforgiving is more likely to have harmful effects on joints because the muscles surrounding them tend not to be as well developed. This would apply in particular to those that have a predisposition to arthritic disease.
