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+a₁x^n-1+a₂x^n-2+....+a_n-1x+a_n=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?

If the entire universe really was smaller than a proton when it started expanding, and it has been expending at a finite rate. Even if explansion during inflation was a number of times faster than light speed, the expansion rate was a finite number. Then how can it reach an infinite size in a finite period of time?

 

Therefore, it appear that the size of the universe is finite.
