Engineering Entrance Exam

Yes, candidates can get admission to the BTech at Amal Jyothi College of Engineering without appearing for the JEE Main exam. The college shortlists candidates based on the scores obtained in the accepted entrance exams and on meeting the course-specific eligibility criteria. The college accepts JEE Main as well as KEAM for its BTech programme. Furthermore, the final selection is based on the overall performance in the selection round.

These are the difference between the alpha, beta and gamma decay:

• Alpha decay: It reduces mass number by 4 and atomic number by 2. It is the emission of a helium nucleus (2 protons, 2 neutrons).
• Beta decay: It changes atomic number by ±1 but there is no change in the mass number. It involves a neutron converting into a proton (or vice versa).
• Gamma decay: Here, there is no change in the atomic or mass number, just the emission of high-energy photons.

Within a nucleus, how tightly nucleons are bound is the binding energy per nucleon. If the binding energy per nucleon is higher then it means more stable nuclei. Iron-56 is the most stable as it has one of the highest values. Both the fusion of light nuclei and the fission of heavy nuclei release energy by moving toward higher binding energy per nucleon.
