7. Force of friction depends upon the area of contact.​

Answer 1

Explanation:

It does not depend the area of contact; it doesn't depend on the sliding speed.

Friction does not depend on the amount of surface area in contact between the moving bodies or (within certain limits) on the relative speed of the bodies.

It does, however, depend on the magnitude of the forces holding the bodies together.
