My notes a container is divided into two equal compartments by a partition. one compartment is initially filled with helium at a temperature of 240 k; the other is filled with nitrogen at a temperature of 315 k. both gases are at the same pressure. if we remove the partition and allow the gases to mix, what will be their final temperature?

i wanna say it’s between b and d, leaning more towards b.

be subject to a force andchange its motion

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
