Why no one is mentioning what the experiment say.. I read somewhere that when you use a low energy probe you sea only three constituents- the quarks, but when you use high energy probes you can see many other centers and these are the sea quarks. Now the question is how many!

The potential energy is 'electrostatic' and it is stored in the container 'walls' in the form of stress. Without walls there can be no pressure- accept in the case of massive objects like planets with large enough gravity. The container is stressed and when the gas expands for example, the...

-Simplify the problem by taking unit masses and cancelling the 1/2 factor. v1+v2=u1+u2; v1^2+v2^2=u1^2+u2^2. Square the two sides of the first equation and subtract from the second and get; v1*v2=u1*u2 as a solution satisfying both conditions. This remains correct if the masses are not equal...

[Benson:Mar5-12, 07:58 AM Re: Conceptual derivation of (classical mechanical) energy? #57] Just to complete my answer above; To find the dynamic response of the container with stirrer, heating and losses; Increase in temp per second=(heating power+stirrer power -lost...

In an isolated system all the input Heating Energy will go into increasing the internal temperature after some time. This increase involves the heat capacity of the liquid as is well known. The input KE also becomes eventually internal energy and causes an additional increase in temperature to...

Assuming the see-saw is anchored in the middle, apply Newtons second law for circular motion. That is the total rotating moment( force x arm) = polar moment of inertia x angular acceleration. The net force is weight(gravity force with direction taken correctly) x arm . Integrating this gives...

See for example PHYSNET, 'THE MAGNETIC FIELD OF A MOVING CHARG', EQ (4)- gives a clear derivation.

Many thanks for the valuable information and sorry about the wrong cutting in your article. I am a newish user, so forgive me.

Dear all It is known that the ratio of the magnetic attraction to the static repulsion of two moving (similar) charges is in the ratio of (v/c)^2. A learned friend of mine tells me that this is relativistically correct also. When v is nearly c, the two forces are equal and we have an...

Many thanks for taking the time to comment. I personally think there is a misunderstanding of the curved space concept. I understand that Einstein is not calling for a bent space, but bent space-time which is different. Space alone is always flat.

Dear all I have come with a simple idea to generate the three laws of motion of Newton and would love to hear comments on its correctness. Assume equal point masses: the rule says ' the displacement of one point mass must be balanced by an equal and opposite displacement of another'. Since all...
