Select the correct answer from each drop-down menu. The carbon cycle can interact with the water cycle.
For example, when people burn fossil fuels, pollutants can enter the atmosphere and mix with the water vapor that is
condensing
to form clouds. This polluted water falls to the surface as acid rain.
carries the polluted water by gravity along the Earth’s surface.

Explanation:

Carbon is an essential element in the bodies of living organisms. It is also economically important to modern humans, in the form of fossil fuels.

Carbon dioxide {CO}_2CO 2

Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales.

Some human activities, such as the burning of fossil fuels and deforestation, increase atmospheric {CO}_2CO2

answer is 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
