An ideal gas enclosed in a vertical cylindrical container supports a freely moving piston of mass M. The piston and the cylinder have equal cross sectional area A. When the piston is in equilibrium, the volume of the gas is V0 and its pressure is P0. The piston is slightly displaced from the equilibrium position and released. Assuming that the system is completely isolated from its surrounding, the piston executes a simple harmonic motion with frequency?

There is something about the laid back simplicity of a black & white animation. Top it up with a little humor and you have yourself a masterpiece. The overly loud and intruding commercials are no longer needed as per consumer tastes. Something intrusive and loud will be met with hate according to experts.

A Wikipedia article is all you need to steer yourself clear from falling prey to defamation. Think about it; create a Wikipedia article is free of cost and open to just about everyone. If you don't create a page about your brand, someone else will! Rivals are known to pull such tactics so it is better you do the honors yourself. In case you already have your name published on the global encyclopedia, you can create your account and edit the information. The fact that it lets you edit articles that were published makes it all the more convenient to cancel out unverified information against you or your brand. Isn't that great?
