How can I differentiate ground state and excited state hadrons ? What is the difference between their quantum numbers?

Two balls was stayed in a same hieght. After that i let them go it at the same time.

A concave mirror forms a double real body of the object on the screen. Now the screen and object are arranged in such a manner that the four-dimension of the object is formed on the screen. Therefore, ...

I'm just learned about water. I got confused at capillary action, adhesion and one more thing. And about pouring water on a string. Are that also an example of capillary action?

A rotation $R(\hat{\textbf{n}},\phi)$ in the three-dimensional physical space, about an arbitrary axis $\hat{\textbf{n}}$ through an angle $\phi$ is given by $$R(\hat{\textbf{n}},\phi)=e^{-i(\textbf{j}...

I have the following question that is assigned for homework, provided with my approach to it: My approach involves considering the equation for magnetic force: $F = \frac{μ_0 × I_1 × I_2 × L}{2πr}$ ...

In physical three-dimensional space, a rotation about an arbitrary axies $\hat{\textbf{n}}$ through an angle $\phi$ can be represented by $$R(\hat{\textbf{n}},\phi)=e^{-i(\textbf{J}\cdot\hat{\textbf{n}...

Though it seems to be very simple question but I want help where I am lacking.Two charges say one of 10C and other of 1C how can they exert same force.Say a charge of ten coloumb will surely attract ...

What would happen if the universal constants had different values? what happens if one of them changes in the near future?

Say I have some arbitrary finite charge distribution $\rho(\vec{r})$ that generates an electric field $\vec{E}(\vec{r})$. Now take any arbitrary surface $S$ that surrounds this distribution. If I put ...

I'm stuck with a problem one of my friends posed to me a few weeks ago, he said it's appeared in an Olympiad before. First, I present the problem statement: Consider the given arrangement, ...

Mass $M_1=1 kg$ is suspended from a light string to form a simple pendulum. Length of the string is $L=2 m$ . It is taken aside through $60 °$ is released. At the lowest point , $M_1$ collides with ...

In this video, why does the longitudinal nature along with transverse nature is felt for sound wave? Is this because of the tube(containing the vibrating particles)?

I am wondering how General relativity holds up if we treat time differently than the 3 spatial components. Consider the modified Einstein equations $$ R_{ab}-\frac{1}{2}Rg_{ab}+\Lambda g_{ab} = 8\pi G ...

I am going to school to be a biomedical technician so I have a little but very limited amount of knowledge on radiation but base on what I learned each time we get exposed to radiation we receive a ...
