1. When a body falls freely towards the earth‚ then its total energy (a) increases (b) decreases (c) remains constant (d) first increases and then decreases 2. A car is accelerated on a levelled road and attains a velocity 4 times of its initial velocity. In this process the potential energy of the car (a) does not change (b) becomes twice to that of initial (c) becomes 4 times that of initial (d) becomes 16 times that of initial 3. In case of negative work the angle between the force and displacement

levels affect photosynthesis rate Phaladi Phaladi 201102379 Department Of Mathematics And Science Education University Of Botswana Plants‚ through the use of chlorophyll (green pigment in plants) that traps light can generate ‘food’ by combining carbon dioxide in the air and water. As with many chemical process energy is need to make and break molecules during the chemical process. The greater the light levels the more energy is available to carry out process of photosynthesis. Some photosynthesis

AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis is: Photosynthesis

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

SCIENTIFIC REPORT ON THE EFFECT OF WAVELENGTH ON PHOTOSYNTHESIS Red wavelengths will increase the rate of photosynthesis to a greater degree than blue or green wavelengths and thus will be the most optimal for plant growth. This hypothesis will be tested under laboratory conditions using silver beet extracts and DCPIP under different wavelengths and assessing the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic

Natural fibres are usually staple‚ whilst man-made fibres are filament‚ with the exception of silk that comes from a natural source. These raw fibres are spun to produce a long‚ continuous thread referred to as yarn‚ which is then used in a series of methods that include‚ stitching‚ knitting and weaving in order to produce a fabric. The content‚ construction and finish of a fabric can determine it’s aesthetic and functional qualities. This essay will explore the classifications and characteristics of
