My teacher tell me that in exam one question was 'why we see lightning first and her thunder late?' so one student write that"because our eyes are front and and ears are back "😂😂😂😂

This channel is the best studying channel for me cuz it takes lesser time than other channels and even I can understand everything if i am watching it 1 or 2 day before exam 👍🏻
You are right but not all chapters take less time I know that depends on how much our ch is big but still I prefer to watch their videos on 1.25x which is highest
Ma'am one doubt.. If we wants to charge riffill, we rub it to woollen cloth or a polythene. Than how does one cloud gets charged? Where do it getting been rubbed?
Thank you for your question! When you rub a balloon on your hair, the balloon picks up extra electrons from your hair. Electrons are negatively charged, so the balloon becomes negatively charged. The electrons are transferred from your hair to the balloon because they move more easily than the heavier atoms in your hair. The same thing happens when you rub a balloon on a wool sweater. The balloon picks up electrons from the wool.
The spelling of seismic was written sesmic by Mam avneet that is wrong and the figure of earth was also coz the outer core was mentioned as inner core and inner core was as outer core but the explanation was satisfied 😌

Yes and mostly when rain and there is also air blowing from opposite sides it cause electric charge by friction of droplets happen .now why rain happen because of water vapour and there is also a charge in water vapour when a cloud is full of water vapour it causes rain and when a cloud is full of water vapour there are so many charges and heavy droplets have negative charge and light droplets have positive charge (because of tendency) as we know that heavy droplets are in bottom of cloud and light droplets on top of cloud thats why sometimes light fall on human and houses and on other objects this is because in human and houses and in other objects there is positive charge opposite charges attract each other. since cloud is full of charges they try to burst it out and air is a good insulator of electricity but cloud is full so they forcefully burst out charges and air force fully transfer electric charges not straight ly but in zic zac form thats why we see lighting in zic zac form . Hope this helps🥰🥰
Yeh! Ma'am thankyou for explaining this chapter actually I know this chapter but there was a confusion in What is electroscope so I see your video and my all doughts are clear ... Thanku very much ma'am

Ma'am...I hve a question that our hair are charged so they give the charge to the things...then things become charged...but how our hair charged?What's the process...Kindly tell me

As water vapor rises it often acquires a charge as it interacts with dirt, ice, and other materials during its ascent towards the cloud. Once in the cloud the heavier vapor particles have a negative charge and thus sink to the cloud's bottom.... Hope this helps u...😊
Mam, I'm so satisfied After taking Your Class, The Chapter Explanations are so good, My Tution Teacher Took The test of ch. 8 ( you teach me ) and I scored 50/50 the whole diagram was clear to me and the chapter was also. Thankyou So much for teaching us like this 📚

@@MagnetBrainsEducation thnks but i need one thing to know cn you tell me wht is chrginf by conduction,friction,induction these will come to in my test so cn you tell me
Earthing is the process of passing down the electric current we get from a charged object to the earth. And I don't think it's something u can install 😂lol

Mam I have a doubt Mam agar Ham kisi charging object ko touch karte h to charge hamari body ke through earth me aa jata h to phir hame current kyu lagta h Plz reply
Thank u magnet brain for always clearing my doubts and making me perfect in every subject..❤️tommorow is my exam and iam confused but with ur way of teaching made me perfect...🙏

Question 1. Which of the following cannot be changed easily by friction? (a) A plastic scale (b) A copper rod (c) An inflated balloon (d) A woollen cloth Answer: (b) A copper rod Question 2. When a glass rod is rubbed with a piece of silk cloth the rod (a) and the cloth both acquire a positive charge. (b) becomes positively charged while the cloth has a negative charge. (c) and the cloth both acquire a negative charge. (d) becomes negatively charged while the cloth has a positive charge Answer: (b) becomes positively charged while the cloth has a negative charge. Question 3. Write T against true and F against false in the following statements. (a) Like charges attract each other. (b) A charged glass rod attracts a charged plastic straw. (c) Lightning conductor cannot protect a building from lightning. (d) Earthquakes can be predicted in advance. Answer: (a) False (b) True (c) False (d) False Question 4. Sometimes, a crackling sound is heard while taking off a sweater during winters. Explain. Answer: The electric discharge takes place between the body and the sweater due to friction. At the time of electric discharge some energy is released. In this case energy is released in the form of crackling sound. Question 5. Explain why a charged body loses its charge if we touch it with our hand. Human body is a conductor of electricity. When a charged body is touched with hand, our body conducts its charges to the earth. Hence, by this way charged body loses its charge. Question 6. Name the scale on which the destructive energy of an earthquake is measured. An earthquake measures 3 on this scale. Would it be recorded by a seismograph? Is it likely to cause much damage? Solution: The destructive energy of an earthquake is measured on a scale called the Richter Scale. Yes, it would be recorded by seismograph because this scale has the readings from 1 to 10. No it is not likely to cause much damage as earthquakes of magnitude higher than 5 is considered destructive in nature. Question 7. Suggest three measures to protect ourselves from lightning. (i) Do not use TV or cable phone during lightning. (ii) Stay indoor or under covered area. (iii) Don’t take bath during lightning. Question 8. Explain why a charged balloon is repelled by another charged balloon whereas an uncharged balloon is attracted by another charged balloon? Answer: A charged balloon is repelled by another charged balloon because both carry same type of charges. On the other hand, an uncharged balloon is attracted by another charged balloon as they have opposite charges. We know that same charges repel and opposite charges attract each other. Question 9. Describe with the help of a diagram an instrument which can be used to detect a charged body. Answer: Electroscope is a device which is used to detect the charge on a body. It works on the principle that like charges repel each other while unlike charges attract each other. It consists of a metal rod with thin metal strip or leaf attached to it at the bottom. Question 11. Suppose you are outside your home and an earthquake strikes. What precaution would you take to protect yourself? Answer: We will take the following precautions to protect ourselves: (i) Move to open space. Find a clean spot away from buildings, trees and overhead power lines. Drop to the ground. (ii) If we are in a car or a bus, will not come out. Drive slowly to a clear spot and remain in it till the earthquake stops Question 12. The weather department has predicted that a thunderstorm is likely to occur on a certain day. Suppose you have to go out on that day. Would you carry an umbrella? Explain. Answer: No, it is not advisable to carry an umbrella at all. Its metallic objects are more prone to lightning stroke. So an umbrella increases the risk.

Due to the vast number of particles within the Earth and the Moon, the net charge of both bodies is approximately zero which brings the electrostatic force equation to zero. this is what google showed. So maybe not idk

Question:- *why we see the light first and listen the sound after in the lighting* Answers:- Topper:- *Because light travel faster than the sound* Backbencher:- *It because our eye is in front side and our ears is behind that why we see the light first and listen the sound after*
