What is the 'Law of Solid friction?
The Law of Solid Friction states that the force of friction between two surfaces is proportional to the normal force pressing the surfaces together and is independent of the contact area between the surfaces. This law applies as long as the surfaces are not in relative motion.
What type of surfaces have little friction?
smooth surfaces
Can there be a frictional force between two surfaces when there is no relative motion between the two?
Yes, friction can occur between two surfaces even when there is no relative motion. This type of friction is called static friction and acts to prevent the surfaces from sliding past each other. Static friction can build up as long as an external force trying to move the surfaces is resisted by an equal and opposite force of friction.
What is the difference between the way black and white surfaces affect light?
White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat.

Black surfaces do not reflect light and they absorb heat.
What factors influence the level of friction between two surfaces?
The level of friction between two surfaces is influenced by factors such as the roughness of the surfaces, the force pressing the surfaces together, and the type of material the surfaces are made of.
How long does ringworm live on surfaces?
Ringworm can survive on surfaces for several months, depending on the environment. It thrives in warm, moist areas and can live on surfaces like floors, towels, and clothing for up to 18 months. Regular cleaning and disinfecting of surfaces can help reduce the risk of transmission.
How long do Schnauzer dogs live?
its schnauzers not snowzers and they can live up to about 20 years
How long do germs live in the air?
Germs can stay alive in air for up to 48 hours after leaving an infected person or animal. Some germs can live up to a week on surfaces they infect. It is best to keep hands washed, and surfaces sterile to kill germs.
Can scabies live on concrete?
Scabies mites do not live long off a human host; they typically survive for 2 to 3 days without direct contact with skin. On surfaces like concrete, they are unlikely to survive for long, as the environment is not conducive to their needs. Therefore, while they may temporarily be present on concrete, they cannot live there for extended periods. Proper cleaning and disinfection can effectively eliminate any potential mites from surfaces.
How long does mrsa live on surfaces cdc?
According to the CDC, MRSA (methicillin-resistant Staphylococcus aureus) can survive on surfaces for varying lengths of time, ranging from hours to days, depending on the surface type and environmental conditions. It can persist longer on hard surfaces compared to soft materials. Regular cleaning and disinfection of surfaces can help reduce the risk of MRSA transmission.
Can a rabbit live on concrete?
No, rabbits can't live on concrete. Concrete is too hard for a rabbit's feet, in the long term. Rabbits don't have pads on their feet to protect them from hard surfaces. Rabbits naturally spend their time on grass and dirt and other soft surfaces. Rabbits that spend too much time on hard surfaces like concrete suffer from sore hocks (injuries on their heels).
Where do crinoids live?
they live in the ocean. mostly, they are attached to rocks or other hard surfaces.
How long can c-diff live outside the body?
Clostridium difficile (C. diff) bacteria can survive for long periods outside the body, especially in a healthcare setting where surfaces may not be properly cleaned. The spores can survive on surfaces for months and are resistant to many disinfectants. It is important to follow proper cleaning protocols to prevent the spread of C. diff.
Can MRSA live on surface?
MRSA is a very tough cootie. It can survive in organic and inorganic surfaces for more than 100 days.
How long can hiv virus live in open air?
The length of time that cold or flu germs can survive outside the body on an environmental surface, such as a doorknob, varies greatly. But the suspected range is from a few seconds to 48 hours - depending on the specific virus and the type of surface. Flu viruses tend to live longer on surfaces than cold viruses do. Also, it's generally believed that cold and flu viruses live longer on nonporous surfaces - such as plastic, metal or wood - than they do on porous surfaces - such as fabrics, skin or paper.
How long does mononucleosis germ live on surfaces?
The virus that causes mononucleosis, primarily Epstein-Barr virus (EBV), does not survive long on surfaces. It is typically inactivated within a few hours to a day, depending on environmental conditions such as temperature and humidity. Therefore, transmission through surfaces is considered low risk compared to direct contact with infected saliva. Proper hygiene practices, like regular handwashing, can help reduce the risk of transmission.
What do you call animals which live on the surfaces of other animals?
Animals which live on the surface of other animals are called parasites.
