Bladder infections are caused by bacteria in the bladder. Escherichia coli (E. coli) is usually the bacteria that causes a bladder infection. Bladders normally have a small amount of bacteria in them and urinating helps flush out the bacteria, but sometimes the bacteria grows so fast it causes a bladder infection.
aspect ratio. n. 1. The width-to-height ratio of an image or of the area used to display an image. Most widescreen televisions have an aspect ratio of 16:9. 2. The span-to-mean-chord ratio of an airfoil. aspect ratio.
Plotting it out. Below is a graph of how much material (surface area) cans of variable aspect ratio require. On the x-axis is plotted the ratio of h/r (the height to radius ratio). As we can see, the graph has a minimum at h=2r (when the height is the diameter). This is what we calculated with our Calculus.
