A force of 8 N is used to drag a chair 2.5 metres across a room. Calculate the work done to move the chair.

Work is measured in Joule.  The work done by the given chair is 20 J.

Work:

It is defined as the amount change in the energy. It is the product of force applied and displacement due to force.

Formula for work,

W = F x d

Where,

F - Force applied = 8 N  

d - Distance = 2.5 meters  

W - Work done = ?

Put the values in the formula,

Therefore, the work done by the given chair is 20 J.

Explanation:

GIVEN

Force (F) = 8 N

Distance (d) = 2.5 metres

Work done = ?

WE know we have the formula

work done = F * d

Work done = 8 * 2.5

                   = 20 Joule

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.
