To study the properties of various particles, you can accelerate the particles with electric fields. A positron is a particle with the same mass as an electron but the opposite charge ( e). Express your answer in vector form. Do not enter units in your expression. Required:
a. If a positron is accelerated by a constant electric field, find the acceleration of the positron.
b. Assuming the positron started from rest, find the velocity of the positron

a) a = + 1,758 10¹¹ m / s ,  b)  = √ (2 1,758 10¹¹ E x)

Explanation:

a) A charged particle is an electric field undergoing force given by the expression

          F = qE

where q is the charge of the paticle and E electric field.

In this case we are told that the particle is positron

         q = + 1.6 10⁻¹⁹ C

let's calculate the force

         F = + 1.6 10⁻¹⁹ E

we write the positive sign, to show that the particle accelerates in the same direction of the electric field

let's write Newton's second law to find the acceleration

    F = ma

     a = F / m

     a = + 1.6 10-19 / 9.1 10-31 E

     a = + 1,758 10¹¹ m / s

b) the velocity of the particle starting from rest

       v² = v₀² + 2 a x

       v = √ (2 1,758 10¹¹ E x)

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.
