Question

Suppose a force of 250 N is applied on a surface of 10 m². Calculate the pressure of the same.​

Answer 1

Pressure is defined as the force exerted (on a surface) per unit surface area. Pressure is a scalar.

P = F / A, Its unit is Pascal = Newton / meter². There are also some other units in use for pressure.

1) F = P * A = 50, 000 Pascals * 0.5 meter = 25, 000 Pascals or N/m²

2) Surface Area A = Force / Pressure = 100 N / 500 pa = 1/5 m²

3) Area = 30 cm² = 30 / (100*100) meter²

Pressure = F / A = 300 N / (3/1000) = 100 * 1000 pa = 1 * 10⁵ pa

4 ) Area = 1 cm² = (1/100)² meter²

Force needed = P A = 20, 000 pa * (1/100²) m² = 2 Newtons

Answer 2

Explanation:

Phosphoric acid is added to cola drinks to impart tartness, reduce growth of bacteria and fungi, and improve shelf-life. Citric acid, a substance naturally occurring in citrus drinks and added to many others, imparts a tangy flavor and functions as a preservative.Some farmers of Dokur have own mango and orange orchards. These crops require less water than paddy and can be grown on the land previously used for ground nut cultivation. They grow some groundnut as an intermittent (in between the Trees) crop during rabi season.
