Answer 2

Answer:

When we press the rubber s.ucker on a flat ,smooth, surface , its concave rubber cup gets flattened to a large extent, pushing out most of the air from beneath it. Since very little air remains inside the flattened rubber s.ucker ,therefore the air pressure inside the rubber s.ucker becomes very low.

ii. Inflated Tyre- Inflation pressure plays an important role in carrying the vehicle load. Inflation pressure is vital to safe use of tyres. Under or over inflation may lead to tyre failures and / or unsafe performance of tyres or vehicles. Use of Nitrogen in place of air is also gaining popularity due to its advantages.
