      @@NishaSingh-ni8gd it is easy to push or pull it depends on the mass of the body if the mass of body is less than the body which is applying the force then it is easier to pull but if the body has greater mass than it is easier to push the object.

      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.

    2:22:46 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?

    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.

    • @DarkForgeGamin
      @DarkForgeGamin Год назад

      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

      @zeeyannabi9074 10 месяцев назад +2

      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

    2:23:09 The level of water in the pond will remain the same. When the person throws the stones, the stones move forward and exert a force on the water in the pond. However, according to Newton's third law of motion, the water exerts an equal and opposite force on the stones. This means that the force exerted by the stones on the water is balanced by the force exerted by the water on the stones. Therefore, there is no net force acting on the water, and consequently, the level of water in the pond remains unchanged.

    • @aaiynainmukhtar
      @aaiynainmukhtar Год назад +1

      i agree with the level being the same but not for this reason. Rather, the part of boat which has the stones displaces the water equal to the weight of the stones creating a level of water. As stones go in water they dont bring change in the level however the boat becomes lighter and floats. what do you think?

  • @HarimanasSingh

    Water level of pond will rise because as we throw the heavy stones it will take space of the water and the water in that space will rise and ultimately water level should rise. Note that the water body has to b a swimming pool/small pond where there is a fixed amount of water. If we do the same in a big ocean, nothing will be visible however water level must be rising but in very small magnitude.

    2:02:07 The difficulty in holding a school bag with a thin and strong string is primarily due to the pressure exerted by the strap on your shoulder or hand. Here's why:
    1. Pressure and Surface Area Relation:
    Pressure is defined as:
    When the strap is thin, the contact area between the strap and your shoulder or hand is very small. For the same weight (force), a smaller contact area leads to higher pressure.
