1. ### Pressure cooker at 1 atmosphere?

Ok thanks man, very helpful :)
2. ### Pressure cooker at 1 atmosphere?

All right so if it says 15 psi its actually 15 psi above atmosphere??
3. ### Pressure cooker at 1 atmosphere?

Hi, I just read that the operating pressure of a standard pressure cooker is 15 psi or about 1 bar and they claim that water boils at 120C or 250F at this pressure. But atmospheric pressure is 1 bar in Paris and almost 1 bar in most countries in the world, here is a link I found...
4. ### Angular momentum conservation of two point masses

The spiral motion happends because the tangential velocity vector gets a component perpendicular to it because of the pulling force and the new vector is composed of the tangential component vitch remains constant and the ortogonal component vitch increases as long as rhe force is acting. So...
5. ### Angular momentum conservation of two point masses

Hi, Lets suppose we have 2 point masses one fixed and imoveable the other rotateing in a perfect circle around the first imoveable one with constant speed. Regardless of vich force is keeping the rotating mass on its circular orbit. It may be a string or gravitational force or whatever...
