A1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.5 cm. liquid flows through the first segment at a speed of 9.0 m/s

a: what is the speed in the second segment? m/s
b: what is the speed in the third segment? m/s
c: what is the volume flow rate through the pipe? l/s

(a) Speed in the second segment=2.25 m/s

(b) Speed in the third segment=36 m/s

(c) Volume=0.02826 L/s

Explanation:

Given Data

r₁=5×10⁻⁴m

r₂=10⁻³m

r₃=2.5×10⁻⁴ m

v₁= 9.0 m/s

For (a) speed in the second segment

From continuity equation

For (b) speed in the third segment

For (c) the volume flow rate through the pipe

The volume flow rate is the same in all three segments and is given as:

As per requirement of question we need to convert volume cubic meter/second to Litre/second for that we need to "multiply the volume /second value by 1000"

So

Volume=(2.86×10⁻⁵ ×1000) L/s

Volume=0.02826 L/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.

the total distance traveled by the car is

30km + 49km = 79 km .
