What are two reasons for versioning your still-life project file?
Answer: The first reason for versioning your still-life project file is because this way if by mistake or unfortunate circumstance your files does not open because it became corrupt you can recover the data from an old version file. The second reason is that you can manage to have multiple copies of it in case anything were to happen.
I hope it helps, Regards.
Yes it's true, but that doesn't last very long. It creates a compression of the molecules during exactly half of each vibe, and during the other half, it leans the other way, and the molecules spread out in what's called a "rarefaction" a region of lower-than-normal pressure. This 'train' of compressions and rarefactions is what travels through the air, away from the vibrating object, and it's what some people often call a "sound wave".
