Sir i have a very bothering doubt if it is raining and there is lightning if the lightning strikes the water on the floor how far will the current flow
It has a pendulum basically so as the tremors or seismic waves occur, they pendulum starts vibrating it also has a pen attached to it so as the pendulum moves the pen can note down the power or magnitude of the seismic waves and then the scientists can construct complete map of earthquake they can also estimate its power of destruction caused

Thanks bro 😂😅
U r a g o d
This is called focus 😂😅
@@maacutiepiechannel7619bro its literally AI
@@Shreyash-ku3kwIts a AI who generated it
👇Its vote time lets vote who liked the session
No
No
We already have the like button on the video for that
Yaa💀
We don't like this session we can't understand
Byjus please bring more class 8 sessions
40:43 wherever it will get a chiense….😂😂
😂
20:26 SIR THIS WAS SO DARK🌚
Only legends understand 😈😈🫦🫦
this was the best session by saurabh sir💯💯
and thank you sir for teaching us so nicely💙🙏
Really
Wow❤❤thanks a lot Saurabh sir.u helped me a lot in understanding of this chapter...😊
12:36
Although I lie in the least active zone, it is important for me to take necessary precautions..😅
being in karnataka i am very lucky as there is least chance of earthquake
In which district do you live?
0:13
The explaination is fantastic
SIR WHAT IF IN 25:22 IT WIIL GET DISTRIBUTED IF SO -IVE AND +IVE IS SIDE THAN WHAT IS THE DISTANCE FOR REPLEY PLZ ANSWER
Ha ha sir didn't reply 😂😂
Sach sir pakka samajh me aaya....... thank you so much sir 😊😊😊 . Best teacher ever💯💯
LIGHTNING LIKES TALL THINGS 😅😅😅🌚🌚🌚 🌚🌚
lightening conductor
Thanks❤❤ for explaining in such a ay
18:50
Chemical effects of electric current plss
22:31
In Bengaluru
Noicd I live in your mom
Hi sir lam new student
To kya
Best explaination
13:57 extra protons
sir u r the best and so cool
0:09 here carefully 😲😯
OR 25:
20 TO 25:22
Recording and measuring earthquake
sir, tusi great ho !
Sir you are the best
Sir can you please send the PDF of it
Sir your teaching is very fun to watch
Charge similar like a magnet
58:56 😂😂 59:46 😂😂
What is difference between cells and atomes
Atoms combine to form cells
Assam (Zone 5)
27:6
🌳
Game baj gaya ho ta uska tabhi 35:25
Sir i have a very bothering doubt if it is raining and there is lightning if the lightning strikes the water on the floor how far will the current flow
I think 🧐 when the water falls on the ground and the ground absorb the charges
More than explaining sir you are taking with them
Nice class
This was a great session
sir if plates move all over the world shouldn't earthquakes be more often
Kal kiska paper hai 🙃😂aur abhi padhai ho rhi hai
59:10
Yes😊
Sir what happens, if we bring a neutral object near the electroscope?
true
Good evening sir
Tree
❤
DID YOU KNOW- Lightning is 5 times hotter than the sun's surface i.e. 30,000 degree Celsius
Wow
I didn't know 😅
How does seismograph work ?
It has a pendulum basically so as the tremors or seismic waves occur, they pendulum starts vibrating it also has a pen attached to it so as the pendulum moves the pen can note down the power or magnitude of the seismic waves and then the scientists can construct complete map of earthquake they can also estimate its power of destruction caused
21:11 WHAT
Zone 4
intresting one
Sir but how can we detect that how much is the body charged?
😅😅
Vote for this session.if you learn something new
Positive electrons🫨
Sir why don't the lightning come straight instead of coming in different ways???
Hii
❤
sir electron proton samjh nhi aaye
Prakartik afaat
I am in zone 4 Nepal border MAHARAJGANJ
What is defination of lighting
What causes earthquake
Your mom
(Just a joke)😊
static means rest
THANKS
Yes
Sir what is meaning of atom
Extra electrons😊
Can earthquake cause volcanic eruptions ?

Sir How side negative and pogative tel me
EXAM ON MONDAY HELP
Tusi greatest great ho
🎉🎉🎉🎉
❤❤❤
I live in
tree
Electroscope
Hi😊
Hi sirrrrr
Atoms
Sir take the pen near paper bites
That are in rest
Neutral
hi sir
Is it for ntse?
Madhya Pradesh
SIR DON'T TALK WITH YOUR STUDENTS WHEN YOU ARE DOING CLASS PLEASE 😢
