Shvetank- 94%

In the following first order reactions: A+ "Reagent" overset(K_(1))(rarr) Product B+ "Reagent" overset(K_(2))(rarr) Product The ratio of K_(1)//K_(2) when only 50% of B reacts in a given time when 94% of A has been reacted is:

In the following first order competing reactions A overset(k_(1))rarr B, C overset(k_(2)) rarr D . If only 50% of A have been reacted whereas 94% of C has been reacted in the same time interval then find the ratio of (k_(2))/(k_(1)) .

A motor cycle starts from rest and accelerates along a straight path at 2m//s^(2) . At the starting point of the motor cycle there is a stationary electric siren. How far has the motor cycle gone when the driver hears the frequency of the siren at 94% of its value when the motor cycle was at rest ? (Speed of sound = 330ms^(-2))
