important questions in nuclear physics

The enery required to start the fusion comes from the gravitational force between the particles. Write the name of the electromagnetic radiation which is emitted during a natural radioactivity. E = 2 х (3 х 10 8) 2. Solved Examples of Nuclear Physics. Nuclei can be combined with other nuclei or can break into several. - True, 4. Why Is Heavy Water Used As A Moderator? Here we have provided NCERT Exemplar Problems Solutions along with NCERT Exemplar Problems Class 12.. He also made significant contributions in the field of quantum theory, statistical mechanics and nuclear and particle physics. Based on nuclear physics many other fields have come into picture like nuclear power, nuclear weapons and many more. Write the atomic number and mass number of the element A. 7. 3. Revise nuclear fission and fusion reactions and calculate the energy associated with these processes, as part of Higher Physics. Deflected by electric field : α ray, Null Deflection : γ - ray. If the radiation exposure is 100 R, it may cause leukemia. It is primarily concerned with the arrangement of electrons around There are still some questions beyond the Standard Model of physics, such as the strong CP problem, neutrino mass, matter–antimatter asymmetry, and the … Revision Notes on Nuclear Physics:-Nuclear Physics: - Branch of physics dealing with the study of nucleus is called nuclear Physics. Nature of Propagation of Light; 20. Mr. Ramu is working as an X - ray technician in a hospital. What is the average energy released from a single fission process? Question 15. State Soddy and Fajan’s displacement law. Question: Although important nuclear physics work was to go on in laboratories such as ours had become - and we had to cut down to a lower energy group - it was not fundamentally opening up new insights on the structure of matter. What Is The Difference Between Cathode Ray And Beta Ray? Assertion: Control rods are known as 'neu-tron seeking rods', Reason: Control rods are used to perform sustained nuclear fission reaction. 1. Actually normal on the wave front called RAY, in the beta radiation there is wave packet and hence no wave frant. Nuclear Fusion : Extreme temperature, Nuclear Fission : Room temperature, 3. Einstein’s theory of mass energy equivalence is used in nuclear fission and fusion. Fill in the blanks III. Compare the properties of alpha, beta and gamma radiations. 88Ra226 experiences three α - decay. 2. 9.2. In which of the following, no change in mass number of the daughter nuclei takes place, i) α decay ii) β decay iii) γ decay iv) neutron decay. The minimum mass of fissile material necessary to sustain chain reaction is called "critical mass(m, One Roentgen is defined as the quantity of radioactivity substance which produces a charge of 2.58 x 10. Question 5. 3. So we use heavy water as moderator to slow down neutrons. The minimum mass of fissile material necessary to sustain chain reaction is called "critical mass(mc)". What suggestion will you give to Mr. Ramu? Question 3. 1. The program in atomic physics involves work with simple atomic and molecular systems in the gas phase, at surfaces, and in solids. Shearing stress is the ratio of the tangential force F to the area of … 7. Proton - Proton chain reaction is an example of __________________. Write any two elements which are used for inducing radioactivity? 5. 10. Penetrating power of γ radiation is very high, 9. A cobalt specimen emits induced radiation of 75.6 millicurie per second. Assertion and reason type questions: In a β - decay, the neutron num-ber decreases by one. Microscope. Chain reaction takes place in a nuclear reactor and an atomic bomb. (a) If both the assertion and the reason are true and the reason is the correct explanation of the assertion. (b) If both the assertion and the reason are true, but the reason is not the correct ex-planation of the assertion. Give the reason. Numerical problems: 1. Constituents of nucleus (Nucleons) :- (a) Protons:-Mass of proton, m p = 1.6726×10-27 kg. A lot of energy is released in the process. Use the analogy to fill in the blank VII. Mr. Ramu is working as an X - ray technician in a hospital. Particle physics studies the tiniest particles, nuclear physics look at the atom and its main components. Cadmium rods are provided in nuclear reactors because when we start nuclear reacter then more energy is requird for start the reacter , we can not start nuclear reacter with less energy, the rod is used specially for stopping contact of newtron particles with the system. (BS) Developed by Therithal info, Chennai. 4. Class 10 Physics Notes - Chapter 18 - Atomic and Nuclear Physics - Important Questions for FBISE Papers contain important questions. Ramu can use a pocket Dosimeter that measures exposure to ionizing radiation. ____________ isotope is used for the treatment of cancer. Assertion and reason type questions IX. Identify A, B, C, and D from the following nuclear reactions. Question2: How is energy transformed in windmills? Its scope of study encompasses not only the behavior of objects under the action of forces but also gravitational, electromagnetic, and nuclear force fields. Penetrating power of γ radiation is very low, iii. Since velocity of body remains constant during given time period,so diff.of velocity(constant)with respect to time will be ZERO. Many unsuspecting citizens have been led astray by the example of certain prominent public office holders who insist on pronouncing the word "nuclear" as nuc-u-lar. Solution: Mass defect, m = 2 kg. Bigger nuclues broken to from two lighter nucleus and two or three neutrons is called nuclear fission used for making atom bomb two ligther nucleus joined to form bigger nucleus is called nuclear fussion used for making hydrogen bomb.
