Yeap, after you use y = x -d and split the integral in three: y^2*exp(ay) and d^2*exp(ay) and 2yd*exp(ay) its very easy. The first one gives (π/α)^(3/2) and the second one (π/α)^(1/2). The third one can be found through "derivative integration" if I call it correclty in english?
Well I found the answer today.
The answer from rollcast was wrong as I thought. He was talking about infinite density, not compressibility. Compressibility is the change of density with pressure, not the value of density.
In phase transitions, a system has infinite compressibility, because the...
Correct me if I am wrong, but I think that compressibility, generally tells how difficult it is to compress an object. Meaning, the higher the compressibility, the easier it will be to compress an object with a given pressure.
I was asked in my University to describe an system of infinite...
Hello.
I've read in many books that the orbits of the planets of our Solar system are ellipses.
With the one Focus as the Sun.
Well, what is the other one? I mean every ellipse has two focuses...
Yes! You found it!
I am a 5 years old kid that "steals" topics to gain more posts! Isn't it smart!?
Yayyyy.
Now can someone tell me (if they want to) what fire is, who is pretty sure?
What is flame?
What is fire?
A form of energy?
Or maybe matter?...
Anyone here knows the substance of a flame? If it has.
I don't know but I am sure I would like to know!
Ok, sorry. I was just joking.:P
By the way, I don't think anyone could "define God scientifically." It wouldn't be God if he could...
I didn't also knew that scientists claim that you cannot prove a negative so sorry again.
And I agree with you, you can prove a negative with simple examples...
Wow. Is this a scientific way of proving that God does not exist?
Or did you made up this thought in a conversation about God? :P
Regardless, good thinking.
Seems to be a nice way to prove wrong statements that I wouldn't normally mess with.
Greetings!
Once again I don't know where to classify this tread... sorry.
My Question is the following:
Let's say we have a ball of mass, m. Let the mass be a steal ball for example.
We throw the ball at the floor. The impact that follows surely is a non-conservative impact.
(I hope I said...
Homework Statement
(First of all sorry for my English, I don't know any scientific expressions in English...)
A Force given by the type F=5x + 5 (x at metres, F at Newtons) is applied to a body of mass m while it creates (the Force) an angle φ with the horizontal level. The coefficient of...
