Question

What is the Lift Off weight of GSLV MK 3 ? What is the Maximum Velocity it reaches ? ​

Answer 1

Answer:

The 640 tonne GSLV Mk3 consisted of two S200 solid rocket boosters, an L110 hypergolic liquid core stage powered by two Vikas 2 engines, and a C25 LH2/LOX upper stage powered by a single Indegenous Cryogenic Engine. The solid boosters together weighed 472 tonnes and provided 1,050 tonnes of liftoff thrust.

Answer 2

Some metals are so reactive that they explode on contact with water:

There are certain metals – including potassium, sodium, lithium, rubidium and caesium – that are so reactive that they oxidise (or tarnish) instantly when exposed to air. They can even produce explosions when dropped in water! All elements strive to be chemically stable – in other words, to have a full outer electron shell. To achieve this, metals tend to shed electrons. The alkali metals have only one electron on their outer shell, making them ultra-keen to pass on this unwanted passenger to another element via bonding. As a result they form compounds with other elements so readily that they don’t exist independently in nature.
