How does light travel describe an activity activity which help us understand this |
|
Answer» Answer: Light travels in a straight line. Explanation: Activity to show the same Let us carry out a small activity to show that lightwave travels ALONG a straight line. Take three CD’s and align them together. Align them in such a way that all the CD’s line in a straight line. Now take a CANDLE and place it at the other end. Do make SURE that the tip of the candle and the holes of the CD’s all lie in the straight line. Ensure that the height of the CD’s and the tip of the candle are same. Observe the flame of the candle. We are able to see the flame of the candle because the light wave travels through the holes and reaches our eye. Now if suppose we displace the center of the CD’s we observe that we are not able to see the flame of the candle. Why does that HAPPEN? This is because the light gets blocked. If the light could have the ability to take a curve and travel, we could have seen the lightwave. But since light travels in a straight line, we were unable to see the flame of the candle when the CD is displaced. This proves that light travels along a straight line. |

Oxygen cycle description for 200 words |
|
Answer» Answer: The oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within and between its three main reservoirs; the atmosphere (air), the biosphere (living things), and the LITHOSPHERE (Earth’s crust). The main driving FACTOR of the oxygen cycle is photosynthesis, which is RESPONSIBLE for the modern Earth’s atmosphere and life. The amount of oxygen in and around the earth is fixed. But this oxygen is fed again and again through the WORLD’s living systems in a never-ending CIRCLE called the oxygen cycle. Our needs are just part of this cycle. The cycle involves a continual exchange of gases between the air and animals and plants. In a process called respiration, animals and plants take oxygen from air and give back carbon dioxide. In a process called photosynthesis, plants take carbon dioxide from air and water and give back oxygen. Respiration and photosynthesis are effectively opposite processes.

|
Answer» Explanation: On complete combustion, 0.246 g of an organic compound gave 0.198 g 0f CO2 and 0.1014 g of H2O. What is the ratio of carbon and hydrogen ATOMS in the compound?  Prajith Greninja Answered Oct 2, 2017 Given: mass of organic compound --- 0.246 g mass of CO2 formed ----- 0.198 g percentage of Carbon = 12 x mass of CO2 formed x 100 44 mass of organic compound percentage of carbon = 12 /44 x 0.198/0.246 x 100 percentage of carbon = 2.376/10.824 x 100 % carbon = 0.2195 x 100 %carbon = 21.95 ---------------------------------------------------------- 21.95% of carbon is present in the compound Percentage of hydrogen =2/18× mass of H2O/mass of compound×100 = 2×0.1014×100/18×0.246 = 4.58 Hence,the composition of compounds are CARBON : 21.95% HYDROGEN : 4.58%.
