Compressed air in a vertical cylinder with a piston of radius 0.30m0.30m is used to lift a crate. The minimum pressure of the air in the cylinder needed for the piston to lift the crate is 1.61×105N/m21.61×105N/m2, and the pressure in the room outside the piston is 1.01×105N/m21.01×105N/m2. If the mass of the piston is negligible, the weight of the crate is most nearly

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.
