Which of the following is an example of a solution: the atmosphere, milk, an italian salad dressing, are muddy water

co2reflects heat radiation back to earth buning coal and oil emits co2 globe warms

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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
