Difference between optical and mechanical mouse?
A mechanical mouse has a ball & rollers on the bottom which moves the pointer. An optical mouse has a light instead, and you don't even need a mouse pad to use it.
How does the type of surface affect heating by radiation?
Dark matt surfaces absorb radiated heat much more easily than light-coloured shiny surfaces.
Why does light reflect best on flat and shiny surfaces?
because the light bounces off the flat and shiny surfaces.
Is metal shiny?
Generally the fresh surfaces of metals are shiny.
Why does shiny surfaces absorbe more energy then dull surfaces?
Because, shiny surfaces reflect heat, they don't emit much heat and they don't absorb much heat!
What are shiny surfaces?
a shiny surface so much light so brightly that it seans to glow
Is it true that shiny materials absorb radiant energy?
I believe that shiny surfaces reflect radiant energy.
Why dark surfaces are good absorbers of heat and shiny surfaces are poor absorbers of heat?
If you are talking in terms of the suns heat being absorbed by the surfaces then I have the answer. Shiny surfaces naturally deflect the suns rays where as dark surfaces are easy conductors of heat as they naturally catch the suns rays. You will notice with leather or print on a shirt that it gets hot because the rays have nowhere to go. A shiny surface will just deflect it back.
Is friction will resist motion of an object on shiny surfaces?
Yes.Even if it looks shiny, there's always some friction.
Will friction resist motion of an object on shiny surfaces?
Yes.Even if it looks shiny, there's always some friction.
What point is not necessary for concealment?
shiny surfaces should match surroundings
A typical property of a metal surfaces when freshly cut or polished?
Shiny.
