Suppose your professor handed you a test tube with 3 ml of an e. coli culture in it and told you to make a 10-3 dilution of the entire culture volume with water. what would your final volume (v2) of the dilution need to be in order to get this dilution? hints: use v1d1 =v2d2 and remember to use the d1 of a stock (undiluted sample)

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

its a circle not a square that's simple silly.
