does that mean that if space is indeed infinite, there has to be an infinite amount of planets with every slight variation of life we have here on earth?

ahh, I have to put these into condensed form and simplify

1)2lne+4lne^2-2lne
2)2log0.1+4log0.01-2log0.001

the first one I'm clueless, but I got 1/1000 for the second one...

ahhh THANKS FOR HELPING

Just curious... I don't exactly mean Aliens.. just anything really. Like do you believe other things might exist places besides our planet?

imagine theres a horizontal planeA bove which the effects of gravity are not felt. any object above the plane just floats and gravity has no influence on it.
now take a chain(for e.g:made of small steel ring) of length hundred metres above the planeA and arrange it so that its in a heap just above the planeA. but take care the chain is not entangled and should be easy to stretch along its length.

now pull the lower end of the thread below the planeA and the chain runs down like a single thread and hits the ground and as links pull down on the ones they are linked to , the whole length of the chain will run like a thread and hit the ground in some time. now take planeA is 20metres above the ground surface. the terminal velocity of links when they hit ground will be around 14 metres .
now consider hundred metres of the chain weighs 100 units. the potential energy of the chain just above the planeA will be m*g*h =100 *9.8*20
=19600 units.

There is a group of animals called cattle, in that group three animals are there.
1. Buffalo
2. Cow
3. Goat

Buffalo gives 5 ltrs of milk, Cow gives 2 ltrs of milk, Goat gives 1/4 ltrs of milk,

Arrange the animals in such a way that i can get 40 ltrs of milk and animals should be 19.
