Corona virus increasing day by day

  Lena Ciric, UCL Living under lockdown and the uncertainty that COVID-19 has brought to our lives has been difficult for everyone. We have all welcomed the opportunity to return to a more normal way of life. But a resurgence in cases after the easing of lockdown in many countries shows us that this pandemic is by no means over. We need to remember that now is not the time to relax and take risks. Governments around the world have taken different approaches to responding to the pandemic, but social distancing measures have been a common factor for all. That's because it's one of the most powerful tools we have in preventing the transmission of this disease. The fewer people we interact with, the lower the chances that the virus will spread. This has been a successful strategy to lower numbers of cases. In June and July it was evident that the numbers of new cases were down significantly in Europe, so governments started to relax some of the lockdown measures that had been put i...

Why Muscles breakdown due to exercise  Many of the people go for regular exercise but sometimes they feel that their muscles are paining they think this is due to over exercise but it is wrong, there are many factors for muscle paining.  1. Muscle pains in beinging of exercise  There are many people who even start exercise but all of sudden they start to do exercise, they don't even follow any guidelines by experience people. These people's body in stable state before they are going to start exercising when they start exercises their muscles are disturbed due to these disturbance some of the muscles would breakdown and some of them are replaced their positions due to this their muscles get pained.  2.

If we lift weights o...

Jee advanced important chapters | jee advanced strategy for 2-3 months

Jee advanced strategy 2021 Source :quora  Adil Ali Nirban ,  Mentored A.I.R - 90, 98, 227, 485, 623(JEE,NEET,KVPY) Updated April 10 I hope you did well in JEE Mains and aiming to do great in JEE Advanced as well. If you can work with a proper strategy for the Next two month you can easily get a good rank in JEE Advanced as well. Few important suggestions/strategy for JEE Advanced. Strategy 1 - if you scored 250+ in JEE Mains(I’m assuming you are confident about the theory up to JEE Advanced) Daily you have to do the time-bounded practice of 3hours and after every 3–4 days you need to do time-bounded practice of 6 hours. Re-attempt of important questions(star mark questions) of all the JEE Advanced test which you gave during your last 1–2 years of preparation. DO solve the selective important/star mark questions from your study material and PYQ’s. Proper revision of self-made notes. Do not focus upon any new material in the last 2 months. Strategy 2 - if you scored 250+ in...

VSEPR theory on BrF3 Molecule

Structure of BrF3 Molecule  The central atom Br has seven electrons in the valence shell. Three of these will form electron-pair bonds with three fluorine atoms leaving behind four electrons. Thus, there are three bond pairs and two lone pairs. According to VSEPR theory, these will occupy the corners of a trigonal bipyramid. The two lone pairs will occupy the equatorial positions to minimise lone pair -lone pair and the bond pair -lone pair repulsions which are greater than the bond pair-bond pair repulsions. In addition, the axial fluorine atoms will be bent towards the equatorial fluorine in order to minimise the lone-pair lone-pair repulsions. The shape would be that of a slightly bent T.
