In the above figure, suppose the physical load driven by the motor is increased. The motor slows down, the CEMF ____________________ (increases, decreases), and the voltage at R11 ____________________ (increases, decreases) before it is amplified by op amp 2. The summing op amp produces a ____________________ (less, more) positive voltage, Q1 turns on ____________________ (less, harder), causing the UJT to fire ____________________ (sooner, harder), which ____________________ (increases, decreases) the motor speed back to its desired rpm.

Fill in the blank(s) with the appropriate word(s).
