Determining the effect of pressure on the volume of carbon dioxide.

Explanation:

Identifying the optimal vessel for containing carbon dioxide is an activity that the knowledge gap will naturally be closed after determining the effect of pressure on the volume of carbon dioxide. Also, studying the atomic structure of solid carbon dioxide is not a possible activity because CO₂ is not solid, CO₂ is gas. To observe the natural state of CO₂ is a study that the knowledge gas has been closed and factual.

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
