A potential energy function for a system in which a two-dimensional force acts is of the form U = 3x6y − 5x. Find the force that acts at the point (x, y). (Use the following as necessary: x and y.)

Force,

Explanation:

Given that,

A potential energy function for a system in which a two-dimensional force acts is of the form of :

We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :

So, the force acting at the point (x,y) is . Hence, this is the required solution.

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.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
