Describe Otto von Guericke experiment
Asked by hmhomkar | 26th Jun, 2018, 05:04: PM
A German scientist, Otto Von Guericke placed two hollow metal hemispheres together. Then almost all the air from the combined hemispheres was removed using vacuum pump. The teams of horses were attached at both the ends of hemispheres. These hemispheres were then tried to pull apart from each other by the force of horses. But the air pressure on outside of combined hemispheres were much greater than the air pressure inside them. Thus the hemispheres were unable to seperate from each other. In this way, he demonstrated the experiment of air pressure.

- force acting on an area of 100 cm² is 200N find the pressure acting on this area in N/m²
- The pressure of the inflated balloon is less or greater than the atmospheric pressure? Why? Explain.
- what is pressure
- A car has a weight of 8000N. The car is supported by 4 tyres. The weight on each tyre is equal. The area of one tyre in contact with the ground is 150 cm2 . Calculate the pressure that one tyre exerts on the ground. Show your working and give your answer in N/cm2 .
- 4. You are given the following masses and volumes for various blocks of materials. The mass of 1cm^ 3 of water is 1g.From them choose which one will float in water? (A)materialW:mass=12g,volume=10cm 3 (B)materialY:mass=30g,volume=28cm 3 (C)materialX:mass=22g,volume=20cm3 (D)materialZ;mass=12g,volume=13cm3
- what does pressure depend on?
- 5 applications on atmospheric pressure
- State the characteristics of liquid pressure?
- A nail has 2metre square at one end,1/100m^2 and at the other end. a force of 1000g. weight is applied on the first end calculate the pressure avthing on the wall? Value of g=10m/sec^2
