What is difference beween meson theory and yukawa theory of nuclear forces?
there is no difference b/w meson theory an yukawa theory of nuclear forces because yukawa predicted the nuclear forces as exchange of boson(messons) b/w neutron and proton which keep them bind in an atomic nuclei. so meson theory is just another name of yukawa's theory of nuclear forces.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
Do forces between particles keep particles together or push them away from each other?
electrons
What are pleomorphic nuclei?
cells which keep on changing their shape are called pleomorphic cells
What are the two forces that act together to keep a body in orbit around another body?
gravity and force
When the attractive forces holding particles together are strong enough to hold them together as a group but not as a fixed position they form a what?
Liquid. The liquid state lies between the gaseous and the solid state. The cohesive (attractive) forces between the liquid particles are strong enough to keep them together but not to keep them in a fixed position.
What are nucleons held together by?
The Standard Model of particle theory states that nucleons are bound together primarily by the Strong Interaction Force. These forces keep protons and neutrons together.
Why are enormous amount of energy required to separate nucleus it component protons and neutrons even though protons in the nucleus repel each other?
The forces that binds the protons and neutrons together is called the strong nuclear force and it is about 100 times stronger than the electromagnetic force responsible for the repulsion. So even though the electromagnetic force would help you somewhat with the separation the actual force you need to overcome is still much bigger.
What are three type of weak attractive forces that hold groups of molecules together?
At first place, I think you mean the "INTRAMOLECULAR FORCES" which keep the compounds stable which are not weak.They areIONIC, CO-VALENT & METALLIC forcesWhereas,the weak attractive forces are called "INTER-MOLECULAR FORCES" which keep the different molecules together either due attraction or repulsion between the neighboring particles (could be ions, atoms or molecule).They are 4 types:Dipol - DipolIon -DipolDebye forces (Dipol - induced dipol)London dispersion forces (instantaneous)
Why does a solid have an definite shape?
By definition - that's what makes it a solid.At the atomic or molecular level, the forces between particles (atoms or molecules) are strong enough to keep them in place.
Why can an ideal gas not be liquefied?
An ideal gas is not a real thing, just an idea. The definition of an ideal gas is one where there are no forces between the particles. If there are no forces, there is nothing to bring the particles together into a liquid. In a real gas of course there are forces of attraction which keep the particles together when they are moving sufficiently slowly.
Why dont charged nuclei repel each other in a plasma?
They do. In those plasmas which don't fly apart there are other factors. In plasmas for fusion power, the plasmas are constrained by magnetic forces which keep the material in proximity. There is also the strong nuclear force. This is a very strong force, with a very short range. If two positively charged nuclei can be forced close enough together, then the strong nuclear force, which pulls them together, will become more powerful than the electromagnetic force, which pushes them apart. Then they form one nucleus, and spit out a lot of energy, and sometimes a neutron.
