    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.

    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?

    • @MichelvanBiezen

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

    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!

    Very nice lecture!

    Sir, is the energy released the q value or q value is something else

    • @MichelvanBiezen
      @MichelvanBiezen  7 лет назад +1

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

    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.

    • @MichelvanBiezen
      @MichelvanBiezen  5 лет назад +1

      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)

    I have a question sir. What type of heat transfer being released by nuclear reaction? Conduction, convection or radiation?

    • @MichelvanBiezen
      @MichelvanBiezen  4 года назад

      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?

    • @MichelvanBiezen
      @MichelvanBiezen  4 года назад

      No, the mass of the electrons is accounted for, and is not part of the mass defect.

    • @yugalsharma2773
      @yugalsharma2773 4 года назад

      @@MichelvanBiezen Then does the alpha particle is a full Helium atom(with 2 electrons)?

    • @MichelvanBiezen
      @MichelvanBiezen  4 года назад

      To calculate the mass defect, yes, but depending on the experiment conducted, the answer may be no.
