The movement of a car on a road is represented in this figure. Between t = 0 and t = 0.6 hrs, what is the displacement made by the car? 1). 4.0 km.
2). 0.0 km.
3). -4.0 km. 4
). 8.0 km.

0

Explanation:

On a graph, if there is plot of time vs velocity, then area of velocity plot gives the displacement.

also we can see area of plot is velocity* time which is equal to formula of displacement.

area for this plot is velocity * time

Thus,

from

t =0 to t = 0.2

v = 20

t = 0.2 - 0 = 0.2

thus, displacement till 0.2 seconds = 20*0.2 = 4 Km

from

t =0 to t = 0.4

v = 0

t = 0.4 - 0.2 = 0.2

thus, displacement from  0.2 seconds to 0.4 seconds = 0*0.2 = 0 Km

from

t =0.4 to t = 0.6

v = -20

t = 0.6 - 0.4 = 0.2

thus, displacement from  0.4 seconds to 0.6 seconds = -20*0.2 = -4 Km

Thus, total displacement = 4+0 -4 = 0

Thus, net displacement made by car is 0.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

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.
