Imagine that you have a 6.50 l gas tank and a 4.50 l gas tank. you need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. if you fill the larger tank with oxygen to a pressure of 155 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? assume ideal behavior for all gases. express your answer with the appropriate units.
Answer from: sassyparker1216
V₁(O2) = 6.50 L
p₁(O2) = 155 atm
V₂(acetylene) = 4.50 L
p₂(acetylene) =?
According to Boyle–Mariotte law (At constant temperature and unchanged amount of gas, the product of pressure and volume is constant) we can compare two gases that have ideal behavior and the law can be usefully expressed as:
V₁/p₁ = V₂/p₂
6.5/155 = 4.5/p₂
0.042 x p₂ = 4.5
p₂ = 107.3 atm
p₁(O2) = 155 atm
V₂(acetylene) = 4.50 L
p₂(acetylene) =?

what is the instantaneous acceleration of
the particle at point b?
0 meters/second?
10 meters/second?
12 meters/second?
velocity imetersisecond
15 meters/second?
20
time (seconds)
answer: 0 meters/second^2
Answer from: Quest
we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is
after 28s,
m/s
which i would round to 150 m/s as my final answer
