What must be true of the surface of an object for it to reflect an entire image?
it must be smooth
What must be true of the surface of an object for it to reflect an entire object?
it must be smooth
Does rough surfaces exert greater friction?
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.
How would different types of surfaces affect the bounce of a ball?
It must be ready and get concluding of gravitational of it.and made a completey wool
What surfaces refract light?
For refraction to occur, there must obviously be two different substances that are both transparent to the radiation or waves under consideration. Also, the two substances must have different indices of refraction.
What does ground mean in ground-joint union?
in this application it means ground down as with a grinder to create a smooth flat surface. An explosion-proof rating is achieved when two smooth flat surfaces mate each other tightly but this must be a factory product - it is not something you can create in the field

Should a runway be made smooth or rough?
A runway must be smooth in order for an airplane to land safely on it.
What are two requirements for glue to work?
Make sure the surfaces to be joined are spotlessly clean, and both the surfaces and glue at a good ambient temperature ( ie not very cold or very hot)
When installing a plywood subfloor what must you do to the floor end joints?
Stagger them
What must happen for light to bounce back to see a reflection?
dey must strike on shiony or polished surfaces
