The Fluid Filled Cochlea. The pressure changes in the cochlea caused by sound entering the ear travel down the fluid filled tympanic and vestibular canals which are filled with a fluid called perilymph.
Those who love the size of the original iPad Mini 1 will be pleased to find that the size remains unchanged. Both the iPad Mini 1 and the iPad Mini 2 both measure in with a height of 7.87 inches and a width of 5.3 inches. The iPad Mini has only a slight difference in depth, while it weighs slightly more. However, it is still lightweight enough for anyone who wants a small and portable tablet.
But the mini is actually somewhere between the iPad 2 and the current full-size iPad. The mini uses the same dual-core A5 processor, at the same clock speed, as the iPad 2; includes the same 512MB of RAM; and sports a display with the same resolution, 1024 by 768 pixels.
