You need the radius or diameter of the blender. You need the radius or diameter of the blender. If it's 6 inches. Your answers would be. 71.36 mph @ 4,000 rpm. 356.81 mph @ 20,000 rpm. 3,711 mph if the last one is 208,000 rpm.
Definition of pK a and K a. The definition of K a is: [H + ] . [B] / [HB], where B is the conjugate base of the acid HB. The pK a value is defined from K a, and can be calculated from the K a value from the equation pKa = -Log 10 (K a).
For acid and base dissociation, the same concepts apply, except that we use Ka or Kb instead of Kc. High values of Ka mean that the acid dissociates well and that it is a strong acid. Low values of Ka mean that the acid does not dissociate well and that it is a weak acid. The same logic applies to bases.
