in the particle under constant acceleration model we identify the variables and parameters Vxi, Vxf, ax, t, and xf-xi. Of the equations in the model, Equations 2.13-2.17, the first does not involve xf-x, the second and third do not contain ax, the fourth omits Vxf, and the last leaves out t. So, to complete the set, there should be an equation not involving Vxi. Derive it from the others.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
