The size of skeletal MUSCLE increases by the muscle hypertrophy through growth COMPONENT cells. And it is primarily responsible for strength gaining in the children.2. Neurological factors such as having hyper activeness of the brain structure of the human body that leads to cause a mental disorder. 3. In children, by increasing in strength owing to neural factors leads to produce more potential and it involves the coordination of muscle groups could be partly responsible for strength gaining.

Supplying sufficient clean, fresh water is one of the most vital natural resource issues facing humanity. Water shortages are becoming a global issue, due to an increasing population, economic growth and climate change. A lack of clean, fresh water can hinder the efforts to REDUCE poverty and progress national development, resulting in poor health, low productivity, food insecurity and restricted economic development.In this study session you will learn about the HYDROLOGICAL cycle. You will learn about where fresh water is found, the types of water sources that people use and how important it is to select suitable water sources. FINALLY, you will look at the increasing demands on supplies of fresh water. |

Explain the three laws given by Kepler with the help of diagram |
|
Answer» s Three LawsKepler's Three LawsCircular Motion Principles for SatellitesMathematics of Satellite MotionWeightlessness in OrbitEnergy Relationships for SatellitesIn the early 1600s, Johannes Kepler proposed three laws of planetary motion. Kepler was able to summarize the carefully collected data of his mentor - Tycho Brahe - with three statements that DESCRIBED the motion of planets in a sun-centered solar system. Kepler's efforts to explain the underlying reasons for such motions are no longer accepted; nonetheless, the actual laws themselves are still considered an accurate description of the motion of any planet and any satellite.Kepler's three laws of planetary motion can be described as follows:The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. (The Law of Ellipses)An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time. (The Law of Equal Areas)The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. (The Law of Harmonies) The Law of EllipsesKepler's first law - sometimes referred to as the law of ellipses - explains that planets are orbiting the sun in a path described as an ellipse. An ellipse can easily be constructed using a pencil, two tacks, a string, a sheet of paper and a piece of cardboard. Tack the sheet of paper to the cardboard using the two tacks. Then tie the string into a loop and wrap the loop around the two tacks. Take your pencil and PULL the string until the pencil and two tacks make a triangle (see diagram at the right). Then begin to trace out a path with the pencil, keeping the string wrapped tightly around the tacks. The resulting shape will be an ellipse. An ellipse is a special CURVE in which the sum of the distances from every point on the curve to two other points is a constant. The two other points (represented here by the tack locations) are known as the foci of the ellipse. The closer together that these points are, the more closely that the ellipse RESEMBLES the shape of a CIRCLE. In fact, a circle is the special case of an ellipse in which the two foci are at the same location. Kepler's first law is rather simple - all planets orbit the sun in a path that resembles an ellipse, with the sun being located at one of the foci of that ellipse. |
