Why when popped does a fully inflated balloon make a louder noise than partially inflated balloon?
When a fully inflated balloon is popped, the sudden release of all the stored energy creates a larger shockwave, resulting in a louder noise. In contrast, a partially inflated balloon has less stored energy, so the release of energy upon popping is less intense, leading to a quieter noise.
When a body is fully or partially immersed in a liquid name the force acting on the body?
When a body is fully or partially immersed in a liquid, the force acting on the body is buoyancy, which is directed upwards and is equal to the weight of the liquid displaced by the submerged part of the body.
Is pressure in a balloon less than atmospheric pressure?
Yes, the pressure inside a balloon is typically slightly higher than atmospheric pressure to keep the balloon inflated. When a balloon is fully inflated, the pressure inside the balloon is balanced by the tension in the balloon's material, which allows it to maintain its shape.
What ball will bounce the highest?
A superball will bounce the highest relative to its drop height due to its high elasticity and rebound capability.
Why does the balloon fully inflated with air rise up vertically for some distance when punctured from below?
When the balloon is punctured from below, the air inside the balloon escapes through the hole creating a higher pressure below the balloon compared to above it. This pressure imbalance causes the balloon to move upwards momentarily before it starts to descend due to gravity.
