The is between the mesosphere and the exosphere.
(A) troposphere (B) stratosphere (C) thermosphere (D) exosphere

The __thermosphere is between the mesosphere and the exosphere.

Explanation:

The atmosphere is made up of various layers determined by changes in temperature produced with altitude. From descending to ascending order: exosphere, thermosphere, mesosphere, stratosphere, and troposphere.

c

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

can somebody give me the answer so i can graduate
