Does the frictional force depend on the area of surface contact?
No. Frictional force is independant of surface area.
What are Surfaces that touch food are called?
Surface that touch food are called "food contact surfaces".
When the irregularities of one surface come into contact with those of another surface occurs?
Friction.
What is the angle between ray that strikes a surface and the perpendicular to that surface at the point of contact?
He discorved the colours
When the irregularities of one surface come into contact with those of another surface blank 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.
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
Calculation of contact angle?
Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.
Why does a bike have minimum surface contact?
Minimum is an empty word in these circumstances, but bikes has quite little surface contact due to their narrow tires.
Why do racing cars not have treads?
A tire with a tread has less contact with the road surface than one with no tread. When racing you want to maintain as must tire surface in contact with the racing surface as possible.
