If one can solve 10 each of school prelim papers, sample papers and previous year board question papers and score high then ICSE class 10 can be a cake walk. The rate of radioactive decay cannot be controlled. The nuclear reactor must be shielded with lead and steel walls so as to stop radiations from escaping out to the environment during its normal operation. This is a different “isotope” of uranium called U-235. 9.1 x 10, More deflected than alpha particles but in direction opposite to those of α particles. This extra energy is released in the form of gamma radiation. If the sample is large enough – that is, if many nuclei are present – the actual fraction of it that decays in a certain time span … The source of energy in the Sun and stars is the nucleus fusion of light nuclei such as hydrogen present in them in their inner part. I have read the most of notes on this site and it seems so helpful. It is very important, because U-235 plays a key role in the atomic bomb and nuclear reactors. So the time taken is 5600+5600=11200 years. Keep the radioactive substances in thick lead containers with a very narrow opening, so as to stop radiations coming out from other directions.

So if original was “1”, after 5600 years it will be 1/2. Candidates who are ambitious to qualify the Class 12 with good score can check this article for Notes. Radiation labeled A is gamma radiation because they have no charge and hence under action of magnetic field they go undeflected. Neutrons are bombarded on a heavy nucleus. Gamma radiations like light are not deflected by the electric and magnetic field. Examples of contact forces (frictional force, normal reaction force, tension force as applied through strings and force exerted during collision) and non-contact forces (gravitational, electric and magnetic). Internal source: potassium, carbon and radium are present inside our body. atoms are … There must be back up cooling system for the reactor core, so that in case of failure of one system, the other cooling system could take its place and the core is saved from overheating and melting. Chapter 3—Radioactivity 3-6 state to a lower energy state through the emission of electromagnetic radiation (photons).The number of protons (and neutrons) in the nucleus does not change in this process, so the parent and daughter atoms are the same chemical element. 3. Stream of positively charged particles, i.e. If you could not figure out why a particular option is the answer, feel free to drop a comment below or ask a question in ‘O’ & ‘A’ Level Discussion section of the forum.
