Question

Technician a says that at a microscopic level highly polished metal surfaces are fairly smooth. technician b says oil works by forming a separating film between parts to minimize direct contact between moving parts. who is correct?

Answer 1

Technician A is correct that highly polished metal surfaces are fairly smooth, and Technician B is correct that oil works by forming a separating film between parts to minimize direct contact between moving parts.

Step-by-step explanation:

Technician A is correct. At a microscopic level, highly polished metal surfaces are fairly smooth. This means that the surface of the metal is relatively flat and free from irregularities. Technician A is correct that highly polished metal surfaces are fairly smooth, and Technician B is correct that oil works by forming a separating film between parts to minimize direct contact between moving parts.

Technician B is also correct. Oil works by forming a separating film between parts to minimize direct contact between moving parts. By creating a thin layer of oil between the surfaces, the oil acts as a lubricant and reduces the friction between the parts, allowing them to move more smoothly.
