Neutrons & protons are at rest in the atomic nucleus. In Alpha decay they shoot out of the atom. In alpha decay system loses mass & gains motion in return. In annihilation electron & positron lose their mass &in return photons get their motion. Are mass & motion equivalent?
Hi Professor, absolutely love your lectures as they make physics so easy and fun to learn. But if it may be of convenience, could you release a lecture on background count rate, because I do not quite understand how to tabulate background rate etc.. Much appreciated!
Since different regions in the world use different variables for the same concept. (I would just call it "energy released"). We use q for the heat added to or removed from a gas.
Mr. Biezen, where did you get the value for the mass of the alpha particle? My textbook solution manual used it and i dunno where the hell it came from.
An alpha particle is the nucleus of a helium atom. Look up the nucleus of a helium particle and you'll get the mass. It is approximately 4 x 1.67 x 10^-27 kg (4 times the mass of 1 proton)
These 3 forms of energy transfer take an EXISTING quantity of heat and move it to a different location. In the case of a chemical reaction or a nuclear reaction heat is first generated before it is transferred via some mechanism to other locations.
You are the best teacher i have ever had
You are doing great 👍
I like how you explain your work...makes it easier for one to understand.

Motion and mass is not equivelent, but there is an equation that equates mass to energy (typically kinetic energy). E = mc^2

Very nice lecture!
Sir, is the energy released the q value or q value is something else

Mr Biezen how do you compute the mass of 234 Th given the highest energy as 4196+ - 4 Kev and how do you calculate the uncertainty

Absolutely Brilliant!
I have a question sir. What type of heat transfer being released by nuclear reaction? Conduction, convection or radiation?
These 3 forms of energy transfer take an EXISTING quantity of heat and move it to a different location. In the case of a chemical reaction or a nuclear reaction heat is first generated before it is transferred via some mechanism to other locations.
Ok sir. Thank you!!
Is not the mass defect = mass of the 2 electrons lost from Uranium?
No, the mass of the electrons is accounted for, and is not part of the mass defect.
@@MichelvanBiezen Then does the alpha particle is a full Helium atom(with 2 electrons)?
To calculate the mass defect, yes, but depending on the experiment conducted, the answer may be no.
sorry dear professor, isnt Delta m =2.624 times 10^{-30} ` [kg]?
Woww
My teachers make me hate them
