But the length at the water line of a Nimitz class carrier is 1,040 feet... Based on the well known formula for hull speed(1.34x sqrt of the length of the waterline), that puts the max speed of them at about 43 knots... Or right about 50mph. While some designs allow for exceeding hull speed, It's fairly doubtful that a ship the size of an aircraft carrier can utilize those methods. It's possible that they don't have the engine power to make 43 knots, but I bet that they come very close to it.
Actually, most cats will have an estrus cycle (the technical name for heat) within six to eight weeks after giving birth. In rare occasions, a cat will have an estrus cycle within a week after her kittens were born.
The process of a mama cat getting ready to have kittens is called queening. A female cat can get pregnant when sheâs as young as 4 months old, unless sheâs been spayed to prevent that. Queens can keep going into heat every 2 to 3 weeks from the spring through the early fall, making them ready to reproduce more often than not. A catâs pregnancy lasts about 63-65 days. So, a cat can have kittens when sheâs only 6 months old. Is She Pregnant? The best way to find out is to make an appointment with your vet. He can confirm that kittens are on the way, and get an idea of how many, in a few ways: Feeling your cat's belly is sometimes useful but not always accurate.
