Given that the rates of breakdown of Benzocaine, a local anaesthetic are 16 x 10 second 15 10-8 sec at 30°C and 25°c respectively. Compute the shelf-life of an ampoule (Injection) of the
drug stored in the fridge at 5°C if the compendia provided a preparation of the drug shall contain
not less than 80% of benzocaine.

gas and liquid

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
