Answer 2

Answer:

3.01%

Step-by-step explanation:

Initially, Height of the governor is 400cos30°=346.41 mm= 0.34641 m .

so, Initial speed = $\sqrt (895/0.34641)$ =50.83 rpm.

Again, final height = (346.41-20) mm =326.41 mm= 0.32641m

final speed =$\sqrt(895/0.32641)$ =52.36 rpm.

% increase ={(final speed-initial speed)/Initial speed}*100% =3.01%
