Data CDs, on the other hand, hold anything. Theyâre just another media on which you can store files from your computer. The format of a data CD is even similar to the format of your computerâs hard disk. It has a file system, directories, folders and files. But your car stereo knows nothing about file systems, folders and the like. All it knows is how to stream that raw audio data off of an audio format CD. While your computer can do that it too, itâs also a general-purpose device that understands the format of a data CD. But thatâs not the only difference. Remember that I said that an audio CD is uncompressed.
*To calculate optimal viewing distance in meters instead of feet, the formula is pixel pitch x 2.5. How to estimate optimal display size. Modular, built-to-order Christie Velvet LED display tiles can be configured into virtually any size and shape.
But. h / 5280 is much smaller then 2r, hence 2r + h / 5280 is approximately 2r and thus. Substituting r = 3963 miles give the neat result that if your eyes are h feet above the earth, then the distance to the horizon IN MILES is about. Thus a person 6 feet tall standing on level ground can see for about 3 miles. So, theoretically, a person 6' tall (with binoculars) should be able to see the top of the head of a six-footer who is 6 miles away. He would see the whole person at a distance of 3 miles. Chris.
