How does the roughness of surfaces that are touching affect the friction betwen the surfaces?
The rougher the surfaces the greater the 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.

What type of surfaces might cause a toy car to roll faster or slower?
Faster: Surfaces with less friction (smooth) ;slanted surfaces Slower: Surfaces with more friction (sticky surfaces, rough surfaces), uphill surfaces Of course a slanted surface with too much friction will also make the car slower.
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.
What type of surfaces have little friction?
smooth surfaces
Suggest one way in which iron surfaces can be protected from the formation of iron surfaces?
One way is galvanization; coating with zinc.
Why is it important to know how blood patterns differ on different surfaces?
It is important to know how blood patterns differ on surfaces to provide an interpretation of the physical events which made them. -
What is roulex formation?
This question probably is spelled wrong (roulex). A rouleaux formation is: A stacklike arrangement of red blood cells in blood or in diluted suspensions of blood in which their biconcave surfaces are next to each other.
Why is it important that respiratory surfaces are moist and selectively permeable?
bronchioles.
Why surface area important?
All chemical reactions take place on surfaces = so very important

What four main types of surfaces on Earth that are important for keeping the planet warm?
sun
Why do some metals not react with acid?
Metals whose surfaces are "passivated" by for example the formation of an insoluble oxide do not react with acid. An example is aluminium which is resistant to dilute acid.
What is mount Olympus made of?
Mount Olympus is made of rock peaks which were made by wind and rain. The erosion on various surfaces resulted into the formation of this mountain which is about 3,000 meters high.
Why it is important to clean equipment and surfaces before starting a new task?
because i can cause cross continmation
Does a cube have 4 surfaces or 6 surfaces?
A cube has 6 surfaces
Why is sterilistion important in dentistry?
Sterilization of utensils and surfaces is important in dentistry so as to promote patient care. Harmful bacteria can spread to humans through the use of unsterilized equipment.
