With the help of various sources of information. Enquire about the following: a) Why the thermometer is dipped in a liquid before use. b) Why the thermometer is kept under the tongue. c) Whether the body temperature can be measured by keeping the thermometer at some place other than the mouth. d) Whether the temperature of different parts of the body is the same or different. |
|
Answer» A) a doctor dips the thermometer in a LIQUID before use because are 2 reasons (1) is that any infections of the previous patinet may have does not infect others(2)the mercury level should fall down to below 35 degrees.(2) answer to give a true reading of inner body heat because the intense heat of our body is present under our tongue.domestic animal have a 38.5 degrees celsius & birds have a 37.7.cB) Thermometer is kept under tongue so that the reading which it gives is true , i.e. true reading of the inner body heat. The intense heat of our body is present under our tongue and so it is used under tongue so that we can measure our whole body temperature . The UNDERSIDE of the tongue has the most bloodflow and is more accurate than any part of the mouth. If thermometer will be in contact with air at the same TIME , then it will cool down and will result in giving incorrect reading. So it is kept under tongue.C) The body temperature can be measured by keeping the thermometer at some other place than the mouth:1. We can use temperatures by placing thermometer under arms.. 2. For Infants, doctors uses thermometer near ear to measure temperature.3. On fore head of person where thermometer is kept to record temperature.D) Different body parts have different temperatures and this is evident when a person gets fever.Tongue is always at least 2 degree cooler than armpit. Again, during winters we see that the tip of our nose gets colder while other parts REMAIN warm.We check fever by touching the forehead, hand, and neck etc because those places are relatively WARMER than other body parts.HERE U GO |

) If the Earth shrinks to 50% of its real radius its mass remaining the same, the weight of abody on the Earth will |
|
Answer» Explanation:WEIGHT of the object is given by, W = mg, where g is ACCELERATION due to gravity.and we know as well, acceleration due to gravity is INVERSELY proportional to r² [i.e., g = GM/r² ]so, if earth shrinks to 50% of its real radius. acceleration due to gravity become 4 times of its initial value.then, weight of a body becomes 4 times. i.e. W' = 4mgso, percentage increase = (4mg -mg)/mg × 100 = 300%Thanks!I hope it will HELP you.Good LucK! |

The number of neutrons present in phosphonium ion is ( given mass number P and H is 31 and 1 respectively) a. 16 b. 17 c. 18 d. 19 |
|
Answer» For example, if you have a carbon-11 atom, you can tell that the ATOMIC weight is approximately 11, and you subtract the amount of PROTONS in it. There are 6 protons in a carbon atom so you subtract 6 from 11, which gives you 5. That MEANS that you have 5 NEUTRONS in that atom. The same goes for ions. |

The city which had an Air Quality Index (AQI) ranging from 500-600 in winters, saw an AQI as low as 50. This is a good news for all the Delhi-NCR residents as they can finally breathe clean air after months of dealing with pollution.The sudden drop in pollution levels across the globe has led to a positive effect on the ozone layer. With less vehicles on roads and people being vigilant about their activities, the ozone layer has finally got some breathing space.Clear blue skies and empty roads had become the rarest of rare sites in Delhi, which is always jam-packed with people.
