2:23:01 the level of water will remain the same because ,the person with his boat is already in the water along with stones can't thank you enough sir !!!! my extend my gratitude to you and this channel! you guys r the best!!!!
@kkook_youknow No bro the water will come up because the stones will occupy the space inside the water as the level of water will increase and the boat will float at some more height Thus , The stone will displace the water.
@@abhimudgal8117 No it will stay the same...the boat and stones are already part of the Swimming Pool...the only difference is that they have taken space inside the boat but the boat is also part of the water...so the level of water will stay the same.
They both are the also part of swimming pool so when the stones thrown in downwards position so the level of water will remain same because of stones was in boat in swimming pool
The level of the pond will fall. Here's why: 1. When the stones are in the boat, they push down on it, causing the boat to displace more water. 2. This displaced water raises the water level in the pond. 3. When the stones are thrown into the pond, they sink to the bottom and displace only their own volume of water. 4. The volume of water displaced by the stones in the boat is greater than when they are in the pond because the boat displaces water based on the combined weight of the person and stones. 5. As a result, the overall water level in the pond decreases.

1) when the distance between the object is get tripled then F =1/9 times. 2) when the masses of both the object gets doubled then F=4 times F. 3) when the mass of one object is doubled and distance is reduced to half then F= 8 times F. thank you sir itne maje se physics padane ke liye

2:23:14 The water level will remain same, because as stones will be thrown in the water water would rise, but at the same time, boat will also rise. Therefore, level of water will remain same.
Your way of teaching is great sir. I am preparing for government exams and I am revising ncert physics by watching your lecture videos. Wish I could have a teacher like you when I was in my school days😊
2:22:11 the level of water will remain same as the stones' volume had already made the difference in water level when they were in the boat .So the water level will not rise
2:22:37 The level of the pond will initially rise when the person starts throwing the stones into the water, but it will eventually return to its original level once the stones are fully submerged. When the person throws the stones into the pond, they displace some water, causing the water level to rise temporarily. However, as the stones sink to the bottom of the pond, they displace an amount of water equal to their volume. The water that was displaced initially by the stones' entry into the pond is now replaced by the water displaced by the stones resting on the bottom. Assuming the stones are heavy enough to sink and stay at the bottom of the pond, the overall volume of water in the pond remains the same once the stones have settled. Therefore, the water level will return to its original position.
Wrong answer the water level will decrease as first when the stones were on the boat they applied some pressure on the boat and after they were displaced the pressure on the boat will become lighter and the water level will decrease hence if volume is greater density will be less and in question there are heavy stones so it’s density is greater and volume is less
39:53 (1) Force becomes the 9 times less than the previous value. (2)Force becomes the 4 times more than the previous value. (3)Force becomes the 8 times more than the previous value.
The answer of the last puzzle question was 'same' because when the stones were in a boat there weight is considered to be attached with the boat and when it was thrown in the swimming pool the stones' weight removed from the boat and released into the swimming pool Thanks sir for your great teaching ❤😊
2:22:46 sir' pani ka level up down nhi hoga bcoz stone boats per hai, means ab bhi wo pressure laga rha hai pani par boat ke sath, dubne k baad boat ka pressure kam hoga, aur boat upper aayega,,, jitna pressure phle lag rha tha utna jagah wo le lega dubne k baad , so pressure same that's why water level will not increase! Am i right sir?
39:53 Force reduced 9 times Force becomes 4 times Force becomes 8 times Answers according to me.... I m watching this 1 night before exam 😂 Sir please also teach in NEEV 2.0 batch... Vo teacher bhi acha hai but apka jayada samajh aata hai😢....... Pls.... 😊❤
Simply when we double the mass of one body and half the distance than it become f= G (2m1) × m2 / (r/2) ² Which cames to be f= 2(G×m1×m2)/(r/2)² cuz all the upper values were in multiply When we solve the denominator it gives us the value r²/4 Then the 4 in the denominator get to multiply by 2 on the numerator which gives us f= 8(G×m1×m2)/r² Hope you understand 😊
The pond level will remain same because the person is with it's stones already in boat... So, when he will drop it's stones , The Before( dropping Stones ) Buyoancy will be equal to after ( dropping Stones) Buyoancy... so the pond level will remain same
@@Yashuccoc Bahi water level same hoga because boat ka saath hi stone hai na ki koi external factors sai aaya hai stone throw kanai sai water ka volume up (rise)hoga but boat ka volume bhi to down (fall) dono aapas mai cancel out hoga So result is Remain same
The stones' weight was already contributing to the water displacement when they were on the boat. - When thrown into the water, the stones' weight is still contributing to the same amount of displacement. - Archimedes' Principle states that the buoyancy force (upward) equals the weight of the fluid displaced. - Since the stones' weight hasn't changed, the overall water displacement remains the same.
Thanku so much sir ❤. It is only because of you that I can study physics and can get good grades.. we all need a teacher like you in our schools as well ..❤❤

2:23:01 the level of water will remain the same because ,the person with his boat is already in the water along with stones
can't thank you enough sir !!!! my extend my gratitude to you and this channel! you guys r the best!!!!
@kkook_youknow
No bro the water will come up because the stones will occupy the space inside the water as the level of water will increase and the boat will float at some more height
Thus , The stone will displace the water.
Wrong answer . Water will rise up as stones would occupy some space and displace the water.. this desplaced water will rise up
@@abhimudgal8117 No it will stay the same...the boat and stones are already part of the Swimming Pool...the only difference is that they have taken space inside the boat but the boat is also part of the water...so the level of water will stay the same.
Right answer .I got it in the first, it was quite easy. 😁
They both are the also part of swimming pool so when the stones thrown in downwards position so the level of water will remain same because of stones was in boat in swimming pool
2:22:29 the water will remain the same as the stones are in boat and the weight of the boat + stone are equal when stones are thrown in water
Ya right❤❤😊
If the stones are immersed in a fluid then the water will rise, it's because of the archemedes principal
Yes@@blackphantom7596
The level of the pond will fall. Here's why:
1. When the stones are in the boat, they push down on it, causing the boat to displace more water.
2. This displaced water raises the water level in the pond.
3. When the stones are thrown into the pond, they sink to the bottom and displace only their own volume of water.
4. The volume of water displaced by the stones in the boat is greater than when they are in the pond because the boat displaces water based on the combined weight of the person and stones.
5. As a result, the overall water level in the pond decreases.

2) when the masses of both the object gets doubled then F=4 times F.
3) when the mass of one object is doubled and distance is reduced to half then F= 8 times F.

corrct
2:22:37 The level of the pond will initially rise when the person starts throwing the stones into the water, but it will eventually return to its original level once the stones are fully submerged.
When the person throws the stones into the pond, they displace some water, causing the water level to rise temporarily. However, as the stones sink to the bottom of the pond, they displace an amount of water equal to their volume. The water that was displaced initially by the stones' entry into the pond is now replaced by the water displaced by the stones resting on the bottom.
Assuming the stones are heavy enough to sink and stay at the bottom of the pond, the overall volume of water in the pond remains the same once the stones have settled. Therefore, the water level will return to its original position.
Wrong answer the water level will decrease as first when the stones were on the boat they applied some pressure on the boat and after they were displaced the pressure on the boat will become lighter and the water level will decrease hence if volume is greater density will be less and in question there are heavy stones so it’s density is greater and volume is less

The answer of the last puzzle question was 'same' because when the stones were in a boat there weight is considered to be attached with the boat and when it was thrown in the swimming pool the stones' weight removed from the boat and released into the swimming pool

Yes bro
2:22:46 sir' pani ka level up down nhi hoga bcoz stone boats per hai, means ab bhi wo pressure laga rha hai pani par boat ke sath, dubne k baad boat ka pressure kam hoga, aur boat upper aayega,,, jitna pressure phle lag rha tha utna jagah wo le lega dubne k baad , so pressure same that's why water level will not increase!

can you tell me how did you did it ? pleaseeeee...
How 8 time
Simply when we double the mass of one body and half the distance than it become f= G (2m1) × m2 / (r/2) ²
Which cames to be f= 2(G×m1×m2)/(r/2)² cuz all the upper values were in multiply
When we solve the denominator it gives us the value r²/4
Then the 4 in the denominator get to multiply by 2 on the numerator which gives us f= 8(G×m1×m2)/r²
Hope you understand 😊
😊
I think force will not become 4 times
It will be 2 times .
G×2M × 2m/r²
=G×2(M×m)/r²
F=2times

The stones' weight was already contributing to the water displacement when they were on the boat.
- When thrown into the water, the stones' weight is still contributing to the same amount of displacement.
- Archimedes' Principle states that the buoyancy force (upward) equals the weight of the fluid displaced.
- Since the stones' weight hasn't changed, the overall water displacement remains the same.
