Did those scientists find any evidence of any sexual behaviour between them?
As it is said, since they are in captivity, they could just be shring their grief. Homosexuality is not a natural behavior between animals at all.

Can you put like , first case is true if f(x) is even and if such and such....
I shall study your answer. But from my first reading I need more.
I need a condition to apply to f(x) so I can use each of the above properties.
hhegab
Peace!
I want to know the conditions that must be satisfied by a function
f(x) for any of the following two cases to be true (each case independent from the other);
1- \int^a_{-a} f(x) dx = 2 \int^a_0 f(x) dx
2- \int^a_0 f(x) dx = \int^0_a f(x) dx
They gave me confusion when...
Peace!
I wanted to find the elecric field of the rod to the left and then find the force element acting on the right rod.
I got;
E=\frac{k_eQ}{d(2a+d)}
now,
dF=E\ldot dx
then what shoudl I use for integration limit?
hhegab
Thank you all,
the number 42; I am not sure I owe anything but my good company :)
I really missed this place. I feel I am living again when I came back...life is boring, but some can make it a nice experience....enjoy it here!
hhegab
Peace!
I have a problem when attaching pics to my messages. I can't know about the pixel size of my attached file. How can I know it? And how can I reduce it if it is larger than the limit?
hhegab
PS.
I am not sure if this is the correct place of my post, so please forgive me if it is...
Peace!
The problem is that I can't grasp the answer!
I have tried with the integration but I use different limits for integration. I shall post the answer if you want to.
hhegab
Peace!
I am supposed to find the electric force acting on the right rod due to the rod on the left. each is of length 2a and b > 2a. Each rod carries a charge +Q. I have difficulty in finding the integration, especially its limits.
hhegab
Peace!
I did the problem twice and I had the same answer as that of A M.
Either you gave us a wrong input somewhere, or that the answer you have is not accurate...Please check the problem and the inputs in it.
I have aslo tried to solve it assuming that a charge Q was divided equally...
Peace!
The field lines are perpendicular to the surface, and directed either inward or outward according to the sign of sigma, when they added (vectirially) they will give a zero field.
Also, even in the presence of a field inside the conductor, when we put it an an external elecric field...
Peace,
In Serway's Physics for S&E ,6th edition, chapter 24 section 4 (conducing surfaces), when using Gauss' Law
\oint{\vec{E} \cdot d\vec{A}} = \frac{Q_{enc}}{\epsilon_0}
is used, we have A as the TOTAL surface area not a surface of a particular region on the material under study...
Hi,
I have been a memeber of this forum for sometime and I was not that acive , :zzz: forgive me. I had lots of work and studies to do.
I am back with many questions and hope to be as active as I should be :!!)
I am happy to see myself here again :biggrin:
You can for sure try Schaum's book "Theoretical Mechaincs" this is a very good book and full with problems that will clarify things to u. give it a try.
hhegab
best thing is to re-read the courses you had studied before in ur undergrad. and try to solve the 3 exams released from ETS.
you can share me ur opinions.
as for links,
www.grephysics.com is a nice link
hhegab
I am currently preparing to take the test, I use Halliday and Resnick and also Serway for preparation. I have some schaums books to to review things from it.
I am to take it next nov.
hhegab
PS.
Pple here who have gone through this experience should help us in this please
Solved!
There's a sideways force (Coriolis force) acting on anything moving
towards or away from the axis of rotation in a rotating frame such as
the earth. The Coriolis force per unit mass (acceleration) is:
F1 = 2 Omega x V
where V is the velocity in the rotating frame. The magnitude...
A string has two parts: one with a very high mass density (per unit length), and the other with a very low mass density. A wave with amplitude A moves from the dense part toward the light part. What will be the amplitude of the wave which is transmitted to the light part?

Hi,
I have been trying to solve the following differential equations I was stuck with them. I will appreciate any help from you;
1- 3 y' +3x/y =2(xy)^4
I have tried Bernoulli but I could not get a standard form.
2- x' -2 x y = y exp (-3y^2)[x exp(-y^2)+ 3(x exp(-y^2))^2]
I have tried here...
