Mills‚ 2013). The location of this economic actor in the circular flow diagram is the firm sector (a). General Mills produces goods and services to be sold to consumers (households) such as cereal‚ yogurt‚ meals‚ and snacks. A household (b) generates a payment to General Mills for their products (c) and General Mills receives a return flow of money from the household (d). These two initial transactions start the “circle” of the circular flow diagram. Once General Mills process the payment‚ they

II Uniform Circular Motion A. Nomenclature 1. Speed – magnitude of an objects rate of motion (no direction‚ scalar quantity) 2. Velocity – speed and direction of an objects motion (vector‚ mag & direction) 3. If a car’s speed is constant but direction is changing‚ velocity is changing. 4. 2 ways to change velocity (change speed or change direction). 5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed

Essay on joint family vs. nuclear family system A joint family comprises members of the family that are related one another and share a common ancestry‚ religion‚ and property. All the working members of the family pool together what they earn and ha them over to the head who is usually the eldest. The family head takes care of the entire family. Any member who brings in extra money has equal status. Hence‚ the joint family puts into practice the concept: ’To each according to his needs‚

Maṇḍala is a Sanskrit word that means "circle". In the Buddhist and Hindu religious traditions their sacred art often takes a mandala form. The basic form of most Hindu and Buddhist mandalas is a square with four gates containing a circle with a center point. Each gate is in the shape of a T.[1][2] These mandalas‚ concentric diagrams‚ have spiritual and ritual significance in both Buddhism and Hinduism.[3][4] The term is of Hindu origin and appears in the Rig Veda as the name of the sections of

haze can also cause dry throats and result in flu or runny nose. Moreover‚ some people may come down with sore eyes (conjunctivitis). During this period of time‚ infants‚ young children and the elderly have to take precaution because their immune system is not strong enough to withstand the detrimental effects of the haze. Besides causing ill health‚ the haze can cause serious injuries or lives to be lost. This is because the haze obscures vision on the road or in the air. So if a motorist is
