For mechanical equilibrium of a rigid body, two conditions need to be satisfied:

1. Translational equilibrium: The net external force or the vector sum of all the external forces acting on the body must be zero.i.e 

2.Rotational equilibrium :The net external torque or the vector sum of all the torques acting on the body is zero.

There were many differences in Mandela’s opinion about the meaning of freedom, when he was a little boy and when he became young. While he was a little boy, the meaning of freedom was to run in the fields and to swim in the streams.When he became young, he realised that his freedom was an illusion. Now he had realised that not only his freedom, but also others freedom had been seized. So he felt a hunger for freedom now. He wanted that all the people of his country should live with self-respect. They must do what they liked.

By the formula of ed=%change in quantity demanded ÷%change in price 75/50 =1.5 The ed is 1.5

Given, percentage change in quantity demanded=100% P=Rs.10 P1=Rs.5 P1-P=(-5)Rs. Percentage change in price = -5/10×100=(-50) Elasticity of demand = Percentage change in quantity demanded /percentage change in price = (-)100%/(-50)=2 When quantity demanded falls by 50% Ed=2 Elasticity of demand = Percentage change in quantity demanded /percentage change in price 2 =(-) -50%/percentage change in price Percentage change in price =(-){-50}/2=25% When price of commodity rises by 25%,new price=Rs.10+2.5(25%of Rs.10)=Rs.12.5 Elasticity of demand =2 New price =12.5Rs.

Based on the position of the ovary flowers are categorized to 3 types they are
: Hypogynous, Epigynous, and Perigynous flowers.
Hypogynous: Flowers in which the sepals, petals, and stamens are attached below the ovary are called hypogynous, and the ovaries of such flowers are said to be superior. 
Eg: tomato, tulip, and snapdragon.
Epigynous: Flowers in which the sepals, petals, and stamens appear to be attached to the upper part of the ovary due to the fusion of the hypanthium are called epigynous, and the ovaries of such flowers are said to be inferior.  Eg: daffodil
Perigynous: Flowers types in which the hypanthium forms a cuplike or tubular structure that partly surrounds the ovary are called perigynous. In such flowers, the sepals, petals, and stamens are attached to the rim of the hypanthium, and the ovaries of such flowers are superior.
 Eg: cherry, Prunus

Yesterday I was going to school. On the way I saw a child in the middle of the road. A car was coming at full speed. I shouted at the boy, “Hey, mind the car!” to my shock, the boy did not hear to my warning.

 

It was too late to give him another warning. I dashed to the middle of the road, and pulled him towards me. The boy had a narrow escape. He just looked at me wonderingly. I shouted at him, ‘Are you mad? You could have run over by a car!’ again the boy did not respond! He just kept staring at me!

 

It then struck me, the boy could be suffering from hearing and speaking disabilities. I took him to the nearby police station and reported the matter to the inspector. As I was in the middle of this, a lady came running into the room and hugged the boy with tears streaming down her eyes.

 

The lady was the boy’s mother. She explained to the inspector how the boy had got lost in the crowd. The inspector also explained to the lady how I had saved the boy from getting hurt on the road.

 

The lady thanked me profusely. I went home feeling proud after doing the good deed.

The rulers of Vijayanagara made many innovations in the architectural traditions. They added many new features in the temple architecture. These large structures were a show of their imperial authority. For example, they built gopurams and royal gateways. The towers of the central shrines signalled the presence of the temple from a great distance. But the royal gateways surpassed them in height. They reminded the power of the kings. They showed that the kings had full command over the resources, techniques and skills.

The rulers of Vijayanagara also got built mandapas or pavilions. Besides there were long and pillared corridors that ran around the shrines. There were two main temples—The Virupaksha Temple and the Vitthala Temple. The Virupaksha Temple was built over the centuries. It was constructed in the 9th-10th centuries. But after the establishment of Vijayanagara Empire, it was substantially enlarged. Krishnadeva Raya built a hall in front of the main shrine. It marked his accession to the throne. It was decorated with delicately carved pillars.

Many temple complexes had chariot streets. These streets extended from the temple gopuram in a straight line. They were paved with slabs of stone. They were lined with pillared pavilions. The merchants set up their shops in these pavilions. In other words, the rulers of Vijayanagara built impressive buildings.

CBSE Class:08  Science Revision Notes Chapter – 1 Crop Production and Management In order to provide food for a large population - regular production, proper management and distribution of food is necessary.  Crop : When plants of the same kind are grown and cultivated at one place on a large scale, it is called a crop. In India, crops can be broadly categorised into two types based on seasons - Rabi and Kharif crops.Sowing of seeds at appropriate depths and distances gives good yield. Good variety of seeds are sown after selection of healthy seeds.  Sowing is done by seed drills.Soil needs replenishment and enrichment through the use of organic manure and fertilisers. Use of chemical fertilisers has increased tremendously with the introduction of new crop varieties.  Basic practices of crop production: (i)  Preparation of Soil: One of the most important tasks in agriculture is to turn the soil and loosen it.The process of loosening and turning of the soil is called tilling or ploughing.  (ii) Sowing:  Sowing of seeds at appropriate depths and distances gives good yield. Good variety of seeds is sown after selection of healthy seeds. Sowing is done by seed drills. (iii) Adding Manure and Fertilisers  Soil needs replenishment and enrichment through the use of organic manure and fertilisers. Use of chemical fertilisers has increased tremendously with the introduction of new crop varieties. Fertiliser: The inorganic compounds containing nutrients such as nitrogen, potassium and phosphorus. They are made in the factories. Example: Urea, ammonium sulphate, potash, etc. Manure: A natural substance prepared from decomposition of plant and animal wastes (cow dung, animal bones, dead leaves, dead insects and vegetable wastes) by the action of microbes. (iv)  Irrigation :  Supply of water to crops at appropriate intervals is called irrigation.                 Method of Irrigation:                  (a) Tradition methods of Irrigation: Moat, Chain pump, Dheki, Rahat.                  (b) Modern methods of Irrigation: Sprinkler system, Drip system.          (v) Protection from Weeds:  Weeding involves removal of unwanted and uncultivated         plants called weeds.         (vi) Harvesting:  Harvesting is the cutting of the mature crop manually or by machines.         (vii) Storage Proper storage of grains is necessary to protect them from pests and      microorganisms.Harvested food grains normally contain more moisture than required for      storage. Large scale of storage of grains is done in silos and granaries to protect them from  pest like rats and insects. Farmers store grains in jute bags or metallic bins. Food is also obtained  from animals for which animals are reared. This is called animal husbandry.

In order to provide food for a large population – regular production, proper management and distribution of food is necessary.
