What will be the mass of a 4m3 thin cardboard cube withair enclosed in it imagining weight of cardboard is negligible?
The mass of the 4m³ thin cardboard cube with air enclosed in it will be the mass of the air inside the cube. To calculate the mass, you would need to know the density of air (approximately 1.2 kg/m³ at room temperature and pressure). The mass of the air would be the density of air multiplied by the volume of the cube.

How does a water spider breathe?
If you're asking how it breathes underwater, it lives in a bell-shaped structure ofsilk, (an underwater web) open beneath like a diving bell, and filled withair which the spider carries down in the form of smallbubbles attached one at a time to the spinnerets and hindlegs. . so it basically carries a bubble around with it when its underwater.Water spiders breathe through two small openings on the underside of their abdomen. These openings connect to lung-like organs.
What is the conclusion of the Balloon Rocket Car?
Aballoon rocketis aballoonfilled withair. Besides being simple toys, balloon rockets are a widely used teaching device to demonstrate physical principles and the functioning of arocket.[ 1]To launch a simple rocket, a person releases the opening of a balloon, which is then propelled somewhat randomly by the escape of the air which createsthrust. The flight altitude amounts to some metres. The balloon rocket can be used easily to demonstrate simplephysics, namelyNewton’s third law.[ 2]
