11. A car travels with a speed of 50 km/hr in the 151 30 minutes and 100 kmminutes. What is the total distance covered by the car? |
|
Answer» Answer: To solve this question, there are two methods— Method 1 — Let US first find the speed of the car. Speed = Distance ÷ Time. Therefore, speed = 50 km ÷ 1.5 HOUR = 33.33 km/h. Now, Time is Distance / Speed. So, time taken to cover 100 KMS will be 100/33.33 = 3 hours. Therefore, the car will take 3 hours to cover a distance of 100 kms. Method 2 — The car COVERS 50 km in 1.5 hours. So, the car can cover 100 km in 1.5*2= 3 hours. Concept used :- DOUBLE the distance, double is the time taken. Explanation: Plz mark in brainlest |

1What is the function of digestive enzymes ?ORWhat would be the consequences of deficiency of haemoglobin in ourbody? |
|
Answer» Answer: Digestive enzymes play a key role in breaking down the food you eat. These PROTEINS speed up chemical reactions that turn nutrients into substances that your digestive tract can ABSORB. Your saliva has digestive enzymes in it. Some of your organs, including your PANCREAS, gallbladder, and liver, also RELEASE them. Haemoglobin is the respiratory pigment that transports oxygen to the BODY cells for cellular respiration. Therefore, deficiency of haemoglobin in blood can affect the oxygen supplying capacity of blood. This can lead to deficiency of oxygen in the body cells. It can also lead to a disease called anaemia. |

What is ozone layer depletion???Answer in long |
|
Answer» Answer: Ozone layer depletion is the gradual thinning of the earth’s ozone layer in the upper atmosphere caused due to the release of CHEMICAL compounds containing gaseous bromine or chlorine from industries or other human activities.” What is Ozone Layer Depletion? Ozone layer depletion is the thinning of the ozone layer PRESENT in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created. Some compounds release chlorine and bromine on exposure to high ultraviolet light, which then contributes to the ozone layer depletion. Such compounds are known as Ozone Depleting Substances (ODS). The ozone-depleting substances that contain chlorine include chlorofluorocarbon, carbon tetrachloride, hydrochlorofluorocarbons, and methyl CHLOROFORM. Whereas, the ozone-depleting substances that contain bromine are halons, methyl bromide, and HYDRO bromofluorocarbons. Chlorofluorocarbons are the most abundant ozone-depleting substance. It is only when the chlorine atom reacts with some other MOLECULE, it does not react with ozone. Montreal Protocol was proposed in 1987 to stop the use, production and import of ozone-depleting substances and minimize their concentration in the atmosphere to protect the ozone layer of the earth. Also Read: Environmental Issues Causes of Ozone Layer Depletion The ozone layer depletion is a major concern and is associated with a number of factors. The main causes responsible for the depletion of the ozone layer are listed below: Chlorofluorocarbons Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms. These atoms react with ozone and destroy it. Unregulated Rocket Launches Researches say that the unregulated launching of rockets result in much more depletion of ozone layer than the CFCs do. If not controlled, this might result in a huge loss of the ozone layer by the year 2050. Nitrogenous Compounds The nitrogenous compounds such as NO2, NO, N2O are highly responsible for the depletion of the ozone layer. Natural Causes The ozone layer has been found to be depleted by certain natural processes such as Sun-spots and stratospheric winds. But it does not cause more than 1-2% of the ozone layer depletion. The volcanic eruptions are also responsible for the depletion of the ozone layer. |

Q:-8While doing the experiment of percolation in your field you found that 400ml water takes 10 (05)minutes time then what is the percolation rate of the land? |
|
Answer» Answer: 5 mL/MIN. Explanation: Given, Amount of water = 200 mL PERCOLATION time = 40min RATE of percolation = Amount of water in mL / Percolation time in min =200 / 40 =5 mL/min. Hence, the rate of percolation of water through the given soil sample is 5 mL/min. |
