Acrate is lifted vertically 1.5 m and then heldat rest. the crate has weight 100 n (i. e., it issupported by an upward force of 100 n).how much work was done in lifting thecrate from the ground to its final position? 1. more than 150 j2. 150 j3. a bit less than 150 j4. no work was done.5. none of these

option 1

Explanation:

given,                                    

Weight of crate = 100 N              

Crate is lifted up to height = 1.5 m

Work done =?                    

work = Force  x distance              

work = 100 N    x 1.5 m            

work = 150 J                                        

However, work would be more than the 150 J to lift the crate slightly higher to its final position.

The correct answer is option 1

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.
