Why some people get sleepy while travelling in a bus or car?

 Even through we are well rested beforehand, we always drift off during a long journey by any vehicle.


Why sleepiness strike while travelling  ???


1.  Rhythmic motion 

                   The gentle, low frequency vibrations of a car or bus, mimic the soothing and rocking motion that many people find comforting. This steady movement gives state of relaxation.

3. Lack of natural light

                        Sunlight signal our body when to be awake and when to take rest. The enclosed environment of car or train, limit exposure to natural light. This results in increased desire to sleep.





4.  Fatigue and sleep deprivation 

                        Even a short journey can turn into an unintended nap for those who lack sufficient sleep.





5.  Monotony 

                         Long journeys often lack stimulating activities that could keep the brain engaged.  This makes the brain to enter monotonous state resulting in drowsiness.

Why Pluto is considered as a dwarf planet instead of a planet ???

Pluto dont  satisfy them. Thats why Pluto is not a planet  !!!!


Me :  Which was the condition that Pluto didn't satisfy ???


Aniruddha  :  Pluto don't have its own orbit to circulate around Sun.

                            It uses Neptune's orbit   !!!!


This was new thing to me. 


Me :  If Pluto is using Neptune's orbit , there is a possibility that they may collide with each other.......


Aniruddha  :  Since billions of years,  it is happening.  Both of them didn't collide   !!!!


So, in future  also , both of them may not collide with each other.

Bheja Fry question

 This Bheja Fry question is having an unique answer.


Question 


Take me, add me to myself 

Then again for health 

Now divide by 3, you see

You are staring right back at me  !!!!



Answer 


Let's solve step by step ....





It is given that,    Take me ,  add me to myself

                                  Then again for health 


Let 'me' be  'x'


From the above 2 lines,  it is understood that 

We must add 'x' to itself 2 times 

==>>    x  +   x    +   x    =  3x



Now it is given that divide by  3

==>>    3x  /  3   



Now it is given  You are  staring right back at me !!!

==>>   3x   /   3  =    x   again    !!!



We have got back our variable   !!!



Now  to verify this,

We can put various values of  'x'   from   1  to   infinity  !!!


We will get back the same number  as final answer.....

Question


In mirrors of James Webb Telescope which light weight element is used   ?? 


1.   Berilium

Why is it difficult to balance a stationary two Wheeler?

 Stationary objects experience only gravitational force.


Such objects can be balanced only when -----

 The line connecting the center of gravity of the object towards the earth

Touches the ground at a point within the base of the object.



If the base are is large, like in the case of a 4 wheeler, 

Slight deviations due to external forces such as wind, will not push this point out of the base.

So, it is easy to balance such vehicles.




In the case of two wheelers, the base is very narrow.

Hence any slight disturbances, will push the line of action outside the base area. 


Leading to vehicle becoming imbalanced.

Facial hair can pose a risk to them in flights.
