    WHY PATHOGENS TRAVEL IN SEARCH OF A HOST

    Animals can sometimes carry harmful germs that can spread to people and cause illness – these are known as zoonotic diseases or zoonoses. Zoonotic diseases are caused by harmful germs like viruses, bacterial, parasites, and fungi.

    FIRST MERGER OF TWO BLACK HOLES WITH UNEQUAL MASSES DETECTED

    The analysis of the gravitational wave that was detected a year ago by LIGO has turned out to be from the collision of 2 black holes of unequal mass. This has given us the opportunity to study the gravitational waves with more precision as the signals from unequal masses of black holes are sharper.

    FOR BRICS, CHALLENGES AND OPPORTUNITIES

    As the date for the next BRICS summit (12th BRICS summit, scheduled for July 21-23 in St. Petersburg) there are speculations as to the feasibility of conducting such a summit amid covid19.But in this context a report, “BRICS and the Rivalry Pandemic”, released by Russian think-tank Valdai Club this week, notes that the question of considering BRICS as a global governance institution has now come to the fore.

    • What is BRICS
    • Which nation initiated the negotiation for this grouping
    • Why is BRICS grouping Significant
    • Benefits and Opportunities offered through BRICS
    • Challenges faced by BRICS

     

    QUICK NOD LIKELY FOR CHINA INVESTMENTS

    The outbreak of COVID-19 has adversely affected various firms in India. The Share prices of most of the Indian companies have been falling because of the disruption. The decrease in the share prices has in turn exposed the Indian companies to hostile and opportunistic take over by Chinese Companies.

    Consider the following statements:

    1. Black holes are so massive that escape velocity of this region is equal (or may be higher) than the speed of light

     

    This is incorrect. No speed can be greater than the speed of light.

    SUKRIT DHOBAL ITS ABOUT ESCAPE VELOCITY SPEED REQUIRED MORE OR EQUAL TO LIGHT(IN CASE OF BLACK HOLE). AND ESCAPE VELOCITY IS NOT A OBJECT OR SOMETHING THAT MOVE WITH SPEED, INSTEAD ITS A SORT OF FORCE. JUST LIKE YOU NEED SPEED MORE THAN 11.2 KM/SEC, TO ESCAPE EARTHS ATMOSPHERE. NOW RELATE AND ENJOY
