No. You use whichever applies: if an object is at rest, you use static friction. If it is moving, you use kinetic friction.
in the wheel because the treads on the wheel rub against the ground,causing friction
some examples of thermal energy you could find in your home are light bulbs, microwaves, and even you can make thermal energy when you walk across a carpet in socks, creating friction.
When you rub two things together, the friction between the two things will produce heat.
This presumably refers to friction which we find useful. For instance, if you stand on a ladder which is leaning against a wall, it is friction which stops the ladder from slipping. When you walk, friction between your shoes and the ground enables you to push yourself forwards. If the friction is not big enough, you just slip, as on ice.

i don't know. if its your home work to be done yourself =(. if it isn't good because its a sign of curiosity = )

Friction
To find the velocity ratio of a pulley, you must first find the effort and load distances. then you divide the two and there you have you VR (velocity ratio).
