A70 kg man climbs 4 meters up a tree whats his potential energy relative from the ground

Potential energy of the man relative to the ground can be calculated by using the formula,

P.E = mgh

Here, m is the mass of the man = 70 kg

g is acceleration due to gravity = 9.8 m/s²

h= height above the ground = 4 m

Substituting the value we get,

Potential energy of the man= 70×9.8×4= 2744 J

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.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
