which methods reduce friction?\n increasing speed\n lubricating surfaces\n using sticky materials\n increasing surface roughness

which methods reduce friction?\n increasing speed\n lubricating surfaces\n using sticky materials\n increasing surface roughness

Answer

Brief Explanations:

Friction is the force that resists relative motion between surfaces in contact. Lubricating surfaces creates a thin layer between them, reducing direct contact and thus friction. Increasing speed doesn't directly reduce friction. Using sticky materials and increasing surface roughness both increase friction.

Answer:

B. lubricating surfaces
