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.
You should wait to spay the cat until after the kittens are weened, usually about five weeks. Then you should wait for her to 'dry up', wait for her to stop producing milk. The time this takes varies.The length of time a spay can be performed after she 'drys up' really depends on the veterianarian. think anywhere after 1 day but i could be wrong I just took my dog in to get spayed after having 2 litters. They would not take her if she had nursed within the last month o â¦ r even if she was still producing milk. I would say 6 weeks to 2 months after she has giving birth.
