The sound produced in a flute is due to the vibration of air column in the flute. The frequency of sound produced depends on length. The frequency is inversely proportional to the length of the air column. By closing or opening the holes , the length of the air column is changed and hence the frequency can be changed.
In uniform circular motion, 1. Speed is constant. 2. Velocity is variable and acts along tangential direction at a point. 3. Centripetal Force and acceleration act along the radius towards the centre if the circular path. 4. Centrifugal force appears to act radially outwards. It is a virtual ,fictitious force, not a real force.
