The continental ...........
Explanation:
PE = mgz = 200 * 9.81 *1000 = 1962 KJ
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:
Answer:
"element"= There are four basic sentence patterns based on sentence construction element
solution:
write the coordinates of the points A and B
A= (0,0,14)ft
B= (5,-6,0)ft
write the position vector of a with recpect to b
R_{BA}=(0-5)i+(0-(-6))j+(14-0)k
=-5i+6k+14k
calculation of a magnitude of the vector R_{BA}
\left | R_{BA} \right |=\sqrt{(-5)^2+6^2+14^2}
=\sqrt{25+36+196}
=16.031ft
calculation of the unit vector
\frac{-5i+6k+14k}{16.031}
calculation of the force
F_{BA}=R_{BA}U_{BA}
here, F_{BA} is the magnitude of the force.
substitute 350lb for F_{BA} and (\frac{-5i+6k+14k}{16.031}) for U_{BA}.
F_{BA} = 350 x (\frac{-5i+6k+14k}{16.031})
=-109.2i+131j+305.7k lb
