2) a person lifts a 12.0 kg bucket of water from a well at constant speed. if 4000 j of work are done,
how deep is the well?

33.98m

Explanation:

Work= Force * Distance

Let h be depth of well, m be mass of the bucket and g is gravitational force taken as 9.81

Since we are provided with the amount of work done, the work done by gravitational force

W=Fh=-mgh where F is force.

The W is which implies that the gravitational field surrounding the bucket gains energy as the bucket is lifted. To lift the bucket up, work done by the will be positive to balance with work done by gravitational force

Work done by man= fh = mgh

Substituting m for 12.0Kg, W= 4000J and g=9.81 then we make h the subject

h=

h=

h=33.97893306

Rounding off to 2 decimal places, h=33.98

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.

it's a b and
