Very small forces can have tremendous effects on the motions of every small object. an electron, mass 9.1 x 10 ^-31 kg, exerinces a force of 1.6 x 10^-17 n in a typical electric field at the earths surface. from rest, how much time would it take for the electron to reach the speed of 3.0 x 10^6 m/s?

t = 1.7 x 10⁻⁷ s

Explanation:

Given,

The mass of the electron, m = 9.1 x 10⁻³¹ Kg

The force experienced by the electron, F = 1.6 x 10⁻¹⁷ N

The initial velocity of the electron, u = 0

The final velocity of electron, v = 3.0 x 10⁶ m/s

The acceleration of the electron is given by the relation

                                         a = F/m

                                            = 1.6 x 10⁻¹⁷ N / 9.1 x 10⁻³¹ Kg

                                            = 1.76 x 10¹³ m/s²

Using the first equation of motion

                                        v = u + at

                                        t = (v - u) / a

                                          = (3.0 x 10⁶ - 0) /  1.76 x 10¹³

                                          = 1.7 x 10⁻⁷ s

Hence, the time taken by the electron to reach final speed is, t = 1.7 x 10⁻⁷ s

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.
