True, wetlands help to prevent flooding.
From Grahams Law the rates of effusion of two gases are inversely proportional to the square roots of their molar masses at the same temperature and pressure.
Therefore; R1/R2 = √mm2/√mm1
The molecular mass of Carbon dioxide is 44 g
Hence; 1.8 = √(44/x
3.24 = 44/x
x = 44/3.24
= 13.58
Therefore, the molar mass of the other gas is 13.58 g/mol
Sun and hydrogen are the answers
<span>The
correct answer is C) Identifying areas of rain and identifying speeding
cars </span>
Radars used in predicting rain and
measuring speed make use of the Doppler effect. Waves from the radar bounce
from an object and get reflected back to the source.
B) mid ocean ridge because a rise is a underwater mtn range located where tectonic plates are spreading apart
