Please sir answer this question, when sodium oxide reacts with water forms sodium hydroxide (Na2O + H2O → 2NaOH). In this reaction why sodium oxide with water as requirement of sodium is full filled by 1 atom of oxygen then Na2O is a stable compound. Please sir answer this question. I completely confused in this topic
Sir I have a doubt for chemical reaction chapter that how the valency of polyatomic ions can be calculated and why polyatomic ions are formed plz replay sir with a video 🙏🙏
everything is written in brief history of time and general relativity is discussed in chapter 2 space and time that everything "follows nearest thing to a straight path in a curved space which is called a geodesic"
Sir humne padha hai ki salt water is good conductor of electricity . Toh agar hum kisi beach pe current pass karenge toh kya wo pure duniya ke paani main flow karega?
sir one more doubt.. we know that velocities going together add up. i.e lets assume i am walking on the top aof a train in the same direction as the train then our velocities would add up . but now if we come to light....... if we assume the same scenario, but now having a torch in my hand, if i light up the torch then we should intuitively understand that the speed of the light coming out of that torch will be 'C' + (velocity of the train + my) . If this is true then we would be actually breatking the speed of light without breaking any know laws to a 10th grader.......:) So is the speed of light truly the universal speed limit? I would be gratefull to your answer. Thanks P.S I love your channel :)
Sir why ice floats on water even though it is a solid and most of the time we have seen that a solid substance sinks in liquid substance due to high density(such as wax)? Why ice floats on water and does not sink in it?
During the formation of ice some air particles trapped in it which reduce the density of an ice cube........it is like bicycle tayer which is a solid (having low density than water) but the air inside it reduce its density much more......🌚🌚🌚
@@piusin454 bro this is simple and logical phenomenon.........water has dissolved gaseous molecules and during the solidification of ice not all but some of the gaseous molecules gone trapped in the ice cube and this small amount of trapped molecules are sufficient to decrease the density of ice than water.....🌚🌚🌚
@@piusin454 well during the solidification of 90% matters(which is liquid at room temperature) of world get trapped gaseous molecules in it well these trapped molecules are not sufficient to decrease the density of that matter than the density of water.....
Sir, As we know particles of matter keep on moving constantly, then why does water seems stable when it is kept undisturbed Although movement is constantly happening at molecular level which it's smallest unit. Sir please tell.
I heard that light have momentum but how can this be possible Light consists of massless particles called photons And to have momentum it should have mass but it dont have mass then how does it have momentum Also if a body has momentum then in collision of it with us we feel pain and often get a wound But when light collide with us , there is no pain we feel So how can they say light has momentum? Pls answer sir 🙏
Sir white light comes from sun in our atmosphere any prism are not present how white light split and where if dispersion not happen in atmosphere why sky look blue
How do the light knows the shape , size , colours of the image or object , if it reflects from some body and enters our eyes 👀? I know our brain detects the image ,but still how the light carry the information of the object from it's reflected ? Our brain creates the image , then this world is not like as we see ! How do this actual , real universe look like ? Prof. Rama
hey light does not know colour of the image our brain produce it and about size there are many rays which comes from a single body. The rays of light comes from every single point from a body and enters our eye and forms an exact image of the person when all the rays comes on a point then the image is formed on the retina then optical nerves sends the signal to brain that eye me retina par is is jageh par light fall hui tab hamara brain sabhi light rays ko peechhe ki taraf imagine karta hai aur ek image banata hai aur kyo ki sabhi rays jo brain ne peechhe ki taraf imagine kiya vo sari straight lines hai to use image ka exact size pata chal jata hai par kyo oki image inverted hoti hai to hamara brain usko ek baar aur invert kar deta hai aur bas image ka exact size pata chal gaya brain ko fir vo nai image hamko dikha deta hai

Sir, they say light is a massless object. But i leant that in space mission like mangalyaan, etc have used light as a force to propagate through space without using extra fuel. NOW if they are using light as the propellent, when it strikes the surface of the probe it is passing some of its momentum.(law of conservation of momentum) however, as we know light is a massless object, then how can it be used to propel as momentum is mass*velocity, if mass zero then momentum is also zero. Sir please acknowledge this chat and answer this . I would be grateful Thanks
Wave nature of light fulfills most of the phenomenons as compared to particle nature of light ( except photoelectric effect)such as diffraction, polarisation while particle nature not fulfill this two phenomenos then why we don't consider light as a wave .why it is said that it is not having particle as well as wave nature
@@adityasonawane8912 hey if you will take light as particle then also it proves many things okay but if you want to say light as a particle then you can consider it as a particle and wave at the same time okay

Due to high resistivity of tungsten the electrons have to face a lot of friction due to which light and heat energy is produced and the tungsten get heated in seconds
but in my point of veiw light have mass bcause gravity affects it and also photon has energy so it also has mass as shown in the equations of energy like E= mc * c(e=mc 2), ke = 1/2mv *v(v*v = v2), pe = mgh but that mass of photon is very less(negligible) but it has mass
they say photon's do not have mass because it is negligible means limit tends to 0 but in reality it has mass if you have studied the concept of limits then you will get me

everything is written in brief history of time and general relativity is discussed in chapter 2 space and time that everything "follows nearest thing to a straight path in a curved space which is called a geodesic"
Must reply
If we create same empty space as you explained, we can bend the path of light and make the things invisible.
Is it possible or not?
You are great sir

Sir,
As we know particles of matter keep on moving constantly, then why does water seems stable when it is kept undisturbed
Although movement is constantly happening at molecular level which it's smallest unit.
Sir please tell.
Particles of water or any matter are very small and their motion also small as inter particle force is medium (not less or most ) .
