Question

which factors affect friction between two solid surfaces? select two options. the weight of the objects the surface area of the objects the shape of the objects the roughness of the objects surfaces

Explanation:

Friction between solid surfaces depends on the normal force (related to object weight for horizontal surfaces) and the texture/roughness of the contacting surfaces. Surface area and shape do not impact the magnitude of sliding friction for solid surfaces.

Answer:

the weight of the objects
the roughness of the objects' surfaces
