Both Josef Loschmidt and Amedeo Avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. Neither scientist discovered Avogadro’s number in the form we use it today (6.02 x 10^23). Still, there’s controversy over the name of this number. Research the contributions of these two scientists and how Avogadro’s number got its name. Note the name you think this number should be called, provide key details about each scientist’s contributions to this concept, and give a solid rationale for your case in naming the number.

battery with hi vtge high val resist in series

ok

explanation:

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
