sir ; जो Force sides मे लग रहा था वे energy तो हमारे कोई भी काम नही आया | मशीन में कई ऐसे चीजे होते है जिसका हम पूर्ण उपयोग नहीं कर सकते ! आप सीखाते बहुत अच्छे हो। धन्यवाद असम ( অসম) से।
I have read about the process behind it is momentum but hats off to u sir nobody explained this concept like You. Thanks a lot sir May you live long and stay healthy in your whole life 🙏🙏🙏🙏
Sir, I am from class 10th wanna ask a question→ "do for presence of energy, particle(s) always required? Since as we examine in our surrounding; sound energy is due to systematic movement of air ( or other media) particles, light is due to photons (in particle nature) , etcetera...... If No, then please elucidate!
Sir ek questions tha ki space me jane ke liye velocity 11.2km/s hota hai kyu,jab ki dhire dhire v to ja sakte hai gravitational force ko maintain karke thrust ke sath🤔? Ek techer se puchhe the samajh me nahi aya tha Sir achha se es video ke tarh samjhae please 🙏
Nice explaintion sir. I have a question in Chemistry of ch- Acid, bases and salts, in Chlor-Alkali process. We know that in which, due to electricity, NaCl and H20 break into Na+,Cl- , H+ and OH-. Then why only H+ is attracted to cathode because Na+ also has positive charge. Also, why only Cl- towards anode as OH- can also do so. So, according to this logic, 2Na+ should form sodium (at cathode)and 2OH- may form H2O2 (at anode). So sir, please explain that ?
Sir I have one question- If we started lifting a object from earth it will have potential energy but as get out of Earth's influence in space where does all energy go?? Sir pls reply
Sir, kya sun bhi ghoomta hai Apne axis pe? Sir, mujhe essa Lagta hai ki Jaise earth Apne exis pe ghoomta hai and earth sun ke Charo taraf ghoomta hai and moon earth ki Charo taraf ghoomta hai. Wesai hi sun bhi Apne axis pe ghoomta Hoga and sun ke Charo taraf Baki gharah, and sun ( with our solar system ) Kisi point ( xyz ) ke Charo aur ghoomta Hoga.
Good evening Sir! First of all, Very Very Thanks Mujhe bhi yahi lagta tha ki rocket air ke reaction force ki wajah se urta h. Sir, I have a question. Sir, in class 8, we studied that rocket are of streamlined shape so that they can easily pass through air drag, which pushes them downward. And according to third law of motion, air exerts a reaction force on rocket, which is equal and opposite (in upward direction) of force of gases coming out of rocket. 1st Question:- Sir, it means that air exerts force in both upward and downward direction on the same rocket? 2nd Question According to video, can we say that, When rocket flies in the presence of air, it will fly with greater speed ( as air will exert reaction force on rocket + molecules after reaction will exert force on rocket) than in space? Sir, please please solve it. And Sir, how can I ask my doubts on telegram? Sir, plz solve these doubts....🙏🙏🙏
I have question sir Pani mein jab oxygen hota hai to usee Non pollutant kahate Hain Jo hamare seat ke liye achha hota hai Tab hame q kaha jata ki pani garam kar pina chiya Pani garam khrenge to oxygen nikal jayega to pani to pollutant ho gaya.
Sir i am considering like a nuclear fuel reaction held in the roket that provides much power from which the rocket can cross the gravitational of earth and after crossing earth there has fuel in rocket for travel in space as well as excluding it's useless part and after all it becomes very small
Mera sir jitna science questions solve hoga utna acha sir thank u sir Sir though I am in class9 but still sir ek samay to ma class 11,12 me uthunga , so sir plz plz make videos on each and every science and maths topics class 9,10,11,12 . It's my request sir.
Sir mera abhi bhi isme ek dought hai agar particle or atoms ke andar kinetic energy aane se unme jo random movement hota hai aur unke force ke karan rocket udta hai to **Space me to vacuum hai to udhar particle or atom kaha se aayenge* to phir bhi rocket motion me rahata hai Sir please Give me Answer❤
Sir video was very helpful, but i have doubt, which molecules/atoms are u talking about, also do they go in equal amounts in all directions, if they will not there would be a unbalanced force, so the rocket could move sideways or any other directions Also 🖤 curiously waiting for ur next light Class 10th lecture Sir please answer my silly questions, luv u from kashmir💗💗
This is natural phenomenon when a reaction occurs particles will always moves equally in all direction,,, so we need to assume this that particles will gonin same directions
Sir, Nice video presentation, Thank you, balki aur ek shanka hai, space ki nirvath vatavaran (vacuum) me, space vehicle ki shape kaise maintained rahatha hai?
