Answer:
Explanation:
from the ideal gas law we have
PV = mRT
HERE R is gas constant for dry air = 287 J K^{-1} kg^{-1}
We know by ideal gas law
for m_2
WE KNOW
PV = mRT
V, R and T are constant therefore we have
P is directly proportional to mass
The one fact that needs to be mentioned but isn't given anywhere on or around the graph is: The distance, on the vertical axis, is the distance FROM home. So any point on the graph where the distance is zero ... the point is in the x-axis ... is a point AT home.
Segment D ...
Walking AWAY from home; distance increases as time increases.
Segment B ...
Not walking; distance doesn't change as time increases.
Segment C ...
Walking away from home, but slower than before; distance increases as time increases, but not as fast. Slope is less than segment-D.
Segment A ...
Going home; distance is DEcreasing as time increases. Walking pretty fast ... the slope of the line is steep.
Answer:
Condensation
Explanation:
That is when water from the air collects as a drop. also can be rain.
radiation
when the suns radiation fall on the earth and its objects they receive heat energy and hence get heated. Thus the suns heat reaches the earth by. the process of radiation
