NCERT Solutions for Class 12 Physics Chapter 13 - NucleiShare
Goprep provides students with NCERT Physics Part II Solutions for Class 12th Chapter 13 - Nuclei in order to guide students in studying the important concepts of the Chapter in an efficient way. These NCERT Solutions cover important concepts that are more likely to be asked in the examination and all the answers are prepared from the exam point of view to help students in scoring more marks in the exam.
The best approach to study Physics is to take notes and write down all the important formulas and practice the questions of the book. In this Chapter, you will be going to study the important concepts of the subtopics related to:
- Atomic Masses And Composition Of Nucleus
- Mass-energy And Nuclear Binding Energy
- Size Of The Nucleus
- Law of radioactive decay
- Mass – Energy
- Nuclear binding energy
- Nuclear Force and Radioactivity
- Alpha decay, Beta decay and Gamma decay
- Nuclear Energy
- Nuclear reactor and Nuclear fusion
- Controlled thermonuclear fusion.
NCERT Solutions for Class 12 Physics Chapter 13 - Nuclei
The normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive 146C present with the stable carbon isotope 126C. When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity) ceases and its activity begins to drop. From the known half-life (5730 years) of 146C, and the measured activity, the age of the specimen can be approximately estimated. This is the principle of 146C dating used in archaeology. Suppose a specimen from Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus-Valley civilization.
