True False The splitting of atomic nuclei is called nuclear fission The energy released by the fission of one uranium nucleus is very small relalive Lo} thc hurning o an equivalent mass of gasolinc_ The more prevalent isotope of uranium; 238U, does not typically undergo fission when it absorbs neutrons. Chain reactions are Sclf sustaining events. On average, each reaction event causes one Or' more other reaction events_ Chain reaclions often occur spontancously nalural uranium deposils. Chain reactions are more likely to Occur in larger chunks of uranium than smaller chunks. Critical mass is the maximum amount of mass for which each fission event produces no more fission events. subcritical mass one in which the chain reaction dies out;

Answer true or false. (a) In nuclear fusion, two nuclei combine to form a new nucleus. (b) The energy of the sun is derived from the fusion of two hydrogen-1 $\left(_{1}^{1} \mathrm{H}\right)$ nuclei to form a helium- 4 $\left(_{2}^{4} \mathrm{He}\right)$ nucleus. (c) The energy of the sun occurs because once two hydrogen nuclei fuse, the two positive charges no longer repel each other (d) Fusion of hydrogen nuclei in the sun results in a small decrease in mass, which appears as an equivalent amount of energy. (e) Einstein's famous $E=m c^{2}$ equation refers to the energy released when two particles of the same mass collide with the speed of light. (f) Nuclear fusion occurs only in the sun. (g) Nuclear fusion can be carried out and controlled in the laboratory.

Hello. So here um Part A. We have that. Let's let r be the average number of neutrons released released per fission event. Then each of these neutrons causes another fission event. Each releasing, releasing on average are neutrons for a total here of r squared neutrons on average after the second vision event. So after n vision events we have that our sub end neutrons on average are released. So four are being equal to 2.5 on the sequence that describes the average number of neutrons after end vision events is going to be the sequence here are sub and which is going to be equal To 2.5 to the N. All right. So that we have oops. We have party. All right then for part B. Well, since we have that 2.5 is greater than one. So therefore we have the limit as N approaches infinity of our suburban. Well, the limit there is gonna be equal to infinity that tells us that are given sequence is going to diverge so it diverges and then for part C. Well, um the number of fishing events in the fission chain, right? Um Chain reaction of uranium 2 35 increases without bound leading to a nuclear reaction meltdown or an explosion in a nuclear bomb. So Ka boom. All right. Take care

Hello students in this question we have to statements and statement one it is saying that that each freezing product each season product has more binding energy. More binding energy. What nuclear that is binding energy per nuclear is more than the binding energy per nuclear of the nucleus. Okay, so this statement is a character statement because the fission or fusion occurs to get stability to get stability and stability is achieved when binding energy per nuclear increases. Okay, so it means we can say here that the product will have more binding energy per nuclear than the nucleus. Okay, so this statement is correct statement And also we can say here this stability is achieved by by releasing the energy by releasing the energy. So which is the second statement of the problem. Okay, second statement which is saying that pheasant releases energy. So this is also character statement. And clearly it is representing this statement. Okay, by releasing energy the stability is achieved of the product prison product. Okay, so here both his statement one and two are correct in a statement to is clearly representing his statement one so option A will be the correct answer for this problem. Okay. Thank you.

Hello students in discussion. We have two statements in a statement one. It is saying that in the present reaction in the season reaction the product has the product has more binding energy per nuclear. That is binding energy per nucleus is more than the binding energy per nucleus of the parent atoms. So this statement is a character statement. Okay the product Well this is the fishing creation. So it means that mhm material having high atomic high atomic number as well as high mass number built decay into the decade into the smaller a smaller. So as for the graph we know that as the A decreases the binding energy per nuclear increases. Okay so this statement is correct. A statement and a statement too, which is saying that at atomic number increases the binding energy per nuclear first increases then decreases. Okay so this statement is also corrected statement which is the explanation for this question. Okay so hence we can say here that both statements are correct and a statement to is representing clearly the statement one. So from the given options option, it will be the correct answer for this problem. Okay, So here both statements are correct and representing the second statement is representing the first statement. Okay? Thank you. Mhm.

Hello. And in this question here we're going to be looking at new efficient processes. We want to know which of the following statements is true. So the first statement is that only the number of nuclear remains the same? Well, this is not true as because we have inefficient process. One large nucleus okay, becomes to smaller. Yeah, nuclei Okay. That's what happens inefficient process. So the first statement is not true. The second statement is that only the total number of protons remain the same. However, the total number of protons and the total number of neutrons. Is it the same? Okay, so the second statement, while it's partially correct is not fully true. The third statement says only the number of neutrons remain the same and this is the same as the first. The second statement, there is some truth to it but it's not fully correct. The third one says the total number of protons and the total number of nuclear remain the same while the total number of protons indeed remains the same. But the number of nuclei does not. So this means the final one part. E is correct. Where it says the total number of protons and neutrons remain the same. So E is correct. So that there is the solution to this question and thank you for listening
