Answer:
Branches of physics with real life examples
In measuring and understanding nuclear fission (a real life phenomenon), all branches of theoretical and experimental physics have to be employed. Physics branches needed in it are, radiation detection and measurement, nuclear physics, statistical physics, thermodynamics, and almost all others.
Explanation:
If net charge on one object is doubled, then electric force will also get double. It is because they are directly proportional to each other.
Hope this helps!
Decreases, stays the same, increases.
The volume decreases because as air is cooled, the individual molecules collectively possess less kinetic energy and the distances between them decrease, thus leading to a decrease in the volume they occupy at a certain pressure (please note that my answer only holds under constant pressure; air, as a gas, doesn't actually have a definite volume).
The mass stays the same because physical processes do not create or destroy matter. The law of conservation of mass is obeyed. You're only cooling the air, not adding more air molecules.
The density decreases because as the volume decreases and mass stays the same, you have the same mass occupying a smaller volume. Density is mass divided by volume, so as mass is held constant and volume decreases, density increases.
Answer:
Explanation:
We can use the conservation of the angular momentum.
![L=mvR](https://tex.z-dn.net/?f=L%3DmvR)
![I\omega=mvR](https://tex.z-dn.net/?f=I%5Comega%3DmvR)
Now the Inertia is I(professor_stool) plus mR², that is the momentum inertia of a hoop about central axis.
So we will have:
![(I_{proffesor - stool}+mR^{2})\omega=mvR](https://tex.z-dn.net/?f=%28I_%7Bproffesor%20-%20stool%7D%2BmR%5E%7B2%7D%29%5Comega%3DmvR)
Now, we just need to solve it for ω.
![\omega=\frac{mvR}{I_{proffesor-stool}+mR^{2}}](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7BmvR%7D%7BI_%7Bproffesor-stool%7D%2BmR%5E%7B2%7D%7D)
I hope it helps you!
