How can we Add, Subtract, Multiply, Divide same number in both the sides of an Equation (in Hindi)

In this Mathematics video in Hindi for Class 9 we explained how we can add, subtract, multiply or divide same number in both the sides of an equation.

Sir , atmosphere may be arranged according to density , like outermost atmosphere is denser than the inner atmosphere , is this because of gravity ? And sir I also have doubt in relationship of gravity and density , is there any relation ? 🤔🤔🤔

Greetings sir , I'm Rama and I heartily thanks you for such rare videos for our grades , by the way sir , I have a doubt , we know that air is also a fluid as like water is . When we throw a pebble with high velocity on the surface of water it bounces constantly for some period of time . Air also have similar properties as water have . Then , when our spacecraft enters Earth's atmosphere from the space , it should bounce back as it enters with high momentum . What is your opinion sir ?

When fats are completely digested in the small intestine in the presence and presence of intestinal juices it is converted from fats to fatty acids and glycerol . Not alcohol

[@novaresearchcentre4466]

In physics the rays which are parallel will meet at some point because of presence of some other media, like when light is emitted from the focus of the concave mirror or convex lens it travels parallel . They may intersect at some point because of reflection from some other media. In mathematics we consider the lines or light rays in a system , there is no other media which could interrupt their path .

Good afternoon sir , I have learned a topic called momentum in my previous grade , where I learned its formula momentum=mass*velocity . If we consider raindrops falling , then their momentum should be large and they are opposed by least air drag because of their streamlined shape . Why don't they hit us hardly when it rains ?

Sir, in law of conservation of momentum( when two or more bodies act upon one another their total Momentum remains constant or conserved provided no external forces are acting) . So when frictional force is acting during collision then law of conservation of momentum is not applicable.

The conservation of momentum will work in an isolated system. (Where no external unbalanced force takes place like friction )
