Question

all of the following can occur with a torn disc except: a) change in sanding speed. b) exposure of the backing pad. c) deep scratches. d) surface gouges.

Explanation:

A torn disc in a sanding context can lead to exposure of the backing pad, deep scratches, and surface gouges due to uneven contact. However, it has no direct relation to sanding speed. Sanding speed is typically controlled by the operator or the machine settings and not a consequence of a torn disc.

Answer:

A. Change in sanding speed
