Does the frictional force depend on the area of surface contact?
No. Frictional force is independant of surface area.
Is friction a contact or non contact force?
friction is a contact force
What are Surfaces that touch food are called?
Surface that touch food are called "food contact surfaces".
Is muscular force an example of contact force?
Yes . It is an example for contact force.
When the irregularities of one surface come into contact with those of another surface occurs?
Friction.
Do you have to wash hands after using hand sanitizer?
Not If you don't get your hand soiled with something dirty Normal contact with a patient or a dry surface with possible bacteria is not a problem
Explain what is meant by a food contact surface?
Surface that touch food are called "food contact surfaces".
Does the frictional force depend on the area of surface contact?
No. Frictional force is independant of surface area.
Food contact surface definition?
A food contact surface is any surface of equipment, utensil, containers and wrappings that come into direct contact with food.
What is the effect on coefficient of static friction when side length of a cube of 5 cm is doubled to original?
The surface areas in contact do not affect the coefficient.The surface areas in contact do not affect the coefficient.The surface areas in contact do not affect the coefficient.The surface areas in contact do not affect the coefficient.
When you touch a cold surface does cold travel from the surface to your hand or does energy travel from your hand to the cold surface?
Energy travels from your hand to the surface, because even the slightest touch transfers energy. Cold doesn't transfer from the surface to your hand, your nerves just tell your brain that the surface is cold.
Does cold travel from the surface to your hand or does energy travel from your hand to the cold surface?
Energy travels from your hand to the cold surface. Cold is merely the relative absence of heat.
Is friction a contact or non contact force?
friction is a contact force
What are Surfaces that touch food are called?
Surface that touch food are called "food contact surfaces".
Will radioactive fallout make the surface it comes into contact with radioactive?
Remember, radioactive fallout on a surface does not make the surface itself radioactive. The particles themselves are radioactive, not the surface they come in contact with. The surface can usually be cleaned of any contamination
Where did surface area come from?
Surface area was not invented as its a natural phenomena. However, surface area can be derived mathematically from calculating how much of an object, molecule, and so on are exposed. The contact surface of a flat square of 1-centimeter sides would have a surface area of 1-square cm for example. Understanding the implications of surface area is critical to scientific and engineering disciplines.
Is a simile an example of non verbal communication?
No. Nonverbal communication is body language, posture, hand movement, eye contact, facial expression, etc.
