<span>1. Frictional force</span>
A naturally occurring force related
to two bodies in motion is frictional force. Friction is a type of force which
includes two bodies resisting each other –either motion of solid surfaces,
fluid layers, material elements and compounds gliding against each other. They
key point of this frictional force is that the two forces are in the opposite point
of direction with each other. For example, when you are cold, as you rub your
hands together notice that when your right hand is going upward, your left hand
is downward and thus creates heat. That is one type of friction force outcome,
the heat.
Answer:
Explanation:
First step
To calculate by how much the pressure has been increased we must find a relation between Vrms and the pressure p
Where M is molar mass,R is gas constant and T is temperature
As R and M is constant so we obtain
Vrams∝√T
Second step
From Ideal gas law we know that
we will find that
p∝T
So from first and second step, we can obtain that
Vrms∝√p
And a relation between both of them could be given by:
![\frac{V_{rms1} }{V_{rms2}}=\frac{\sqrt{p_{1} } }{\sqrt{p_{2}} }\\ p_{2}=[\frac{(V_{rms1})^{2} }{(V_{rms2})^{2} }]p_{1}\\ p_{2}=\frac{(276m/s)^{2} }{(176m/s)^{2} } (2atm)\\p_{2}=4.9188atm](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7Brms1%7D%20%7D%7BV_%7Brms2%7D%7D%3D%5Cfrac%7B%5Csqrt%7Bp_%7B1%7D%20%7D%20%7D%7B%5Csqrt%7Bp_%7B2%7D%7D%20%7D%5C%5C%20%20p_%7B2%7D%3D%5B%5Cfrac%7B%28V_%7Brms1%7D%29%5E%7B2%7D%20%20%7D%7B%28V_%7Brms2%7D%29%5E%7B2%7D%20%7D%5Dp_%7B1%7D%5C%5C%20%20p_%7B2%7D%3D%5Cfrac%7B%28276m%2Fs%29%5E%7B2%7D%20%7D%7B%28176m%2Fs%29%5E%7B2%7D%20%7D%20%282atm%29%5C%5Cp_%7B2%7D%3D4.9188atm)
The pressure is increased to 4.1988 atm, so the amount will be given by:
