anonymous · Answer

i hope u r not pulling my leg lol

anonymous · Answer

ah ok. the divergence represents source rate. it measures how much is the source or sink at a point

anonymous · Answer

so example, if I have a container of air and I heated this, so the air will expand, and so its divergence is positive and if I cooled it, it will sink or contract so its divergence is negative

anonymous · Answer

ohh so its all abt density of matter

anonymous · Answer

it measures outgoingness

anonymous · Answer

and other things :D

anonymous · Answer

ohhh i like the word outgoingness its cool

anonymous · Answer

like when thor smashes hammer to floor, there will be a force field on the floor. and we know that the force magnitude decreases as it goes in all direction away from where thor hit the floor, so that will have negative divergence

anonymous · Answer

ok got it Thanks. That was  great explanation :)

anonymous · Answer

I hope not too weird though :))

anonymous · Answer

lol

anonymous · Answer

nah i posted one response already and i will post this too. Its fine its just a preparation thingy i am not marked if  its correct but if i did it
