Astudent applies a horizontal force of 100 n to a 25 kg box causing the block to accelerate at a rate of 1.5 m/s^2. which of the following is the best approximation of the magnitude of the friction force on the box?

By Newton's law Friction= -62.5N

Explanation:

Applying second law of Newton (which is the the sum of the forces is equal to the mass of the object who feels the forces times the acceleration)

Push+Friction=

Which indicates that the friction is opposed to the push and it is really appreciable, that is to say, there is a lot of friction between the box and the floor.

the answer to this question is 60 n

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.
