3 жыл бұрынello friends, today I, Gaurav Thakur have got some amazing challenging toughest questions for you guys. Let' see how many of you can crack the logic of these questions, before I explain. Cause I am damn sure, only 5% of you can answer. So are you ready? Let's start with our questions...
1- There are 2 packed rooms, with one fan in each room. Now if I switch on, only 1 room fan, then after two hours, which room will be cooler? Mind you, the room conditions in both the rooms before switching on the fan were the same. Think... and comment down your answers.
2- Why on ISS, candlelight is spherical in shape? Is gravitational force responsible for this or is it the space atmosphere that causes the candlelight to be spherical in shape? Think wisely, before commenting.
Stay tuned to know more about such toughest question answers in our today's video.

The last question is the famous question answered by feynman, that one should neither choose the path completely by water or completely by land. Although the speed of the person will be more on land but if the path length is more it will slow down the person so person should go on the path some by land and some by water the same phenomenon takes place with light in the form of refraction.

Basically it's better to go from uphill rather than to go straight as the particular water level is high on straight distance and lesser roots to absorb water but the uphill is better as it has less water level due to more absorbing mud and sand present there and there will be less chances of being injured, drown, less oxygen

Last question is very famous question mix concept of differential equations and relative motion in different medium . This case is also given in class 12th NCERT example of chapter ray optics to explain the concept of speed of light in different media .. the boy will neither follow complete water route because speed of boy in water will be less than in land nor he will completely follow land because the two routes will form a triangle and the sum of two smaller side of triangle is always greater than third one .. he will partially follow both land and water route which will depend upon there values after doing differentiation minima concept

@@srijall u r right but i said that same concept of achieving minimum time is given more importance than distance is more or less. Concept: It is not necessary that to achieve least time we should travel a smaller distance.unlike in river boat problem we have to get to other side in least time for we have to travel diagonally instead of straight.WE need to travell diagonally because we dont want to waste our energy in overcoming the velocity of River. :) Now in this problem of guard and drowning man . I the coast guard want get minimal time rather than minimum distance(time is given more priority because he is drowning). For this the coast guard will run along the beach (its obvious that you can run faster on sand than swimming in water)untill he reaches the perpendicular to victim then he will swim towards the victim an save him. Hopefully you understand this now. (1 like for my thumb's 👍👍 the did an awesome job...)

Obviously shortest distance between them is through the water but viscocity (means fluid friction) will reduce our speed in the water. So it's best to go through the other side, where no reduction of speed occurs. So we quickly help the 2nd person.

No as compared to land water would be easier to get through as In swimming, the force produced by the swimmer is equal to the mass of the swimmer multiplied by the acceleration of the swimmer in the water. Do it's better and easier & uses lesser time to save the person in the point D2

The question to the last answer is snell's law i.e. to travel a distance in least time the object should move a distance in optically denser and in optically rarer medium. Mathematically if we assume velocity of man on land is v and in water is v/x then :- Sin∅1/v = sin∅2 × x/v sin∅1 will be 90° and sin∅2 can be represented as perpendicular/ hypotenuse from which we can calculate the distance to which the man should move on land and in water.

13:02 he should go from d2 on land because we need more force to go through water then to run on a land

If A Was In Displacement to B it took much time because to move on the Direct path he have to swim in water which needs more force and energy (^E=^m/t) Which takes more time. In the other situation when he move through the flate surface which needs less Energy and Force (↓Energy= ↓m/t) hence, D1 is lesser the D2 so the correct answer D1😃.❤️

Last question ka answer - land path is ok because water is denser than air and travel through air on land helps you to travel faster😎🧐🧐, sorry for jumbled bakwas english but i mean longer path is faster to travel😅

Because water have resistance ( by 3 state of matter gases have largest space between partical compare then liquid) that's why we choose D2 distances

Last answer : he will travel faster on the land where air is the medium on the other hand incase of water the fluid friction will take place which is directly proportional to the speed of the object , second reason could be the density of both the mediums (even light travel slow in water ) this also justify my answe

When the wave hits the boy either it will throw him in the sand or it may take him more away from the land. In my opinion the coast guard might try to run through land, but factors like friction will work accordingly as walking in sand is very difficult. But a coast guard must be well trained to cope up with the situation.
