The food grains obtained by harvesting the crops are dried in the sunshine before storing to reduce their moisture content.It is necessary to prevent them from spoilage. The higher moisture content in food grains promotes the growth of fungus and moulds on the stored grains which damages them.

Sliding friction

Meghna Thapar 4 years, 10 months ago

Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards.  When a car slows down, the friction between the road and the tires helps to bring the car to a stop as the wheels slow down. It is the friction between the wheels and the brake pads that causes the wheels to slow down.

The living amphibians (frogs, toads, salamanders, and caecilians) depend on aquatic respiration to a degree that varies with species, stage of development, temperature, and season. With the exception of a few frog species that lay eggs on land, all amphibians begin life as completely aquatic larvae. Respiratory gas exchange is conducted through the thin, gas-permeable skin and the gills. In addition to these structures, frog tadpoles use their large tail fins for respiration; the tail fins contain blood vessels and are important respiratory structures because of their large surface area. As amphibian larvae develop, the gills (and in frogs, the tail fin) degenerate, paired lungs develop, and the metamorphosing larvae begin making excursions to the water surface to take air breaths.

The substances that taste sour are called acid and their nature is acidic. The term acid is derived from a Latin word acere which means sour. Examples of acidic substances are Curd containing lactic acid, lemon juice and tomato containing citric acid, and vinegar containing acetic acid.

In acoustics, loudness is the subjective perception of sound pressure. More formally, it is defined as, "That attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud."

Amplitude  the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path

The amount of thrust exerted unit per area is called pressure Ex - compressed spring Extra ting oil from seeds

Yogita Ingle 4 years, 11 months ago

The amount of force exerted (thrust) on a surface per unit area is defined as ‘Pressure’.

or

The force applied perpendicular to the surface of an object per unit area over which that force is distributed.

For example, a brick sitting on a surface exerts a force equal to its weight on the object it is resting on. Now we know that a rectangular brick has a wide surface and a thin surface on the sides. By changing the orientation of the brick resting on a surface, we are effectively changing the pressure acting on the surface by the same brick. See the image below for more information.
