You can solve these problems your-self ==>what will be velocity when object trevells 0 m distance in 0 seconds ==>what will be acceleration when delta velocity=0 and t=0 ==>You did zero work in no time what will be your Power As a matter of fact some mathematical problems are not applicable in physics ==>Answer to 0/0 is mostly applicable in calculus like this (x^2-9)/(x-3) becomes 0/0 when x=0 but if we take x->0 then this becomes 6 that's mean that 0/0 is 6 in this case

[limit(x->+0)1/x=+Inf] [limit(x->-0)1/x=-Inf] That's why +Inf is unequal to -Inf

I need to know about black holes like 1)mass 2)volume 3)speed 3.5)temperature 4)if something goes is black hole what will its speed 5)formation 6)destruction 7)what is its role in universe 8)can we produce them 9)how much it's powerful 10)can we damage black holes 11)is there any power in universe to destroy black holes 12)how much black holes are present in current universe 13)what is relation of black holes with time etc. these are some of question when we want to learn about bh please give answer to each question

Hi I want to solve 3 or 4 or up to n degree equation I tried many time to solve only 3 degree equation but cannot solve ax3+bx2+cx+d=0 x=? a0xn+a1xn-1+a2xn-2+....+an-1x+an=0 what is general formula to calculate value of x? I'm not talking about calculus which can give value of x by Newton's method I want algebraic solution!

I think we should see in another view Drawing a triangle on a flat paper We rotate this paper in 3rd dimension to make curvature As we determine 2D curvature by rotating plane in 3rd dimension So if we want to determine curvature of universe we should see in 4th dimension But I don't know weather the fourth dimension is time or length If 4th dimension is time then according to Einstein's time delay formula universe should be +ve curvature If 4th dimension is also a dimension of length then according to lorentz contraction formula universe should be -ve curvatured I've to know about it!

The curvature of universe is -ve or +ve How to determine it?
