The nuclei require a great amount of energy to overcome the electrostatic force of repulsion between them, meaning that the temperature of the nuclei must be raised to significant values. Please check the specific areas you need with your exam board. Hassan Bajwa.

Cosmic radiation – cosmic rays from space that produce nuclear radiation when they collide, Living organisms – all living organisms contain carbon atoms, some of which could be carbon-14 which is radioactive, Man-made – from medical or industrial sources. Chain Reactions: The neutrons released from fission reactions between Uranium-235 nuclei have a high kinetic energy so are able to induce other fission reaction by being absorbed by other nuclei. This does not include the option unit. Multiply the nucleon number by the rest mass in u. Beta-minus particle (electron) and anti-neutrino are emitted. (adsbygoogle = window.adsbygoogle || []).push({}); PapaCambridge provides Physics (7407, 7408) A Level Notes and Resources that includes topical notes, unit wise notes, quick revision notes, detailed notes and a lot more. Info. AS Papers 1 & 2 Mass Defect: the difference between the mass of a nucleus and the mass of all the individual nucleons that make up the nucleus. When the plants die, the activity of carbon-14 decreases, allowing it to be calculated how old they are. To reduce this, a soft, easily magnetised material can be used to minimise the energy required to magnetise. (amplitude). A transformer changes an alternating p.d.

Charged Particles in a Magnetic Field. The magnetising and demagnetising of the core can also cause energy to be lost as heat. Get Physics AS and A Level Notes here at my new website. The control rods are used to control the rate of the reaction by being lowered into the moderator, which causes the neutrons to be absorbed by the control rods rather than the uranium nuclei, which slows down the reaction. Fission is when large nuclei split into two or more smaller daughter nuclei. Binding Energy: the energy required to separate all of the nucleons in a nucleus. Use these to help revise for exams and to read through as you go along to build understanding. (amplitude) and have no effect on the frequency. Increasing the magnetic flux density will increase the maximum e.m.f. Electricity. A-Level AQA Physics Revision Back to A-Level selection.

Subcritical mass is the concentration which is lower than the critical mass and which allows the rate of reaction to gradually decrease until it just peters out. Complete A level Physics Notes. Fuel rods contain a particular concentration of uranium-235 nuclei. AQA A-Level Biology Revision For each of the papers below, there are revision notes, summary sheets, questions from past exam papers separated by topic and other worksheets. When nucleons join together to form a nucleus, there is a loss in mass, this is called the mass defect and is transformed into energy and released. 06 June 2020 : All content for Physics (7407, 7408) has been updated. These notes cover the main areas of this subject. Whether you're a student currently studying for your GCSEs / A Levels or a university student who still has copies of their GCSE and/or A Level notes on them, I would be extremely grateful to anyone who is willing to help Kipnotes collate more notes so that the site can help more people with their exams in the future. The field lines of the induced magnetic field then cut through the secondary coil, which induces an e.m.f. Technetium-99 is used in tracers to show tissue and organ function. Check out  A Level Physics Past Papers. They induce a current by rotating a coil in a magnetic field to convert kinetic energy into electrical energy. The amount of energy released is equal to the mass defect. It gives more detail on topics that teachers may not be familiar with and should be used alongside the specification. Introduction: Radioactivity is a cool but complex topic – it’s not difficult per se, but unless you do the work beforehand, it can be confusing beyond belief. AS Content A-level Content Paper 3 Practical and Astrophysics ... For instance, the physics notes (found via the A-level project above or through the navigation menu) are written in line with the specification, leaving (hopefully) no stone unturned. This does not include the option unit. Our specifications allow you to choose the context and applications to bring physics to life in the way that best suits the needs of your students. Waves. A full set of A level physics notes free to download. Critical mass is the concentration at which the reaction would be at a constant rate as the likelihood of a neutron encountering a nucleus is 1 in 3. to a different peak value using electromagnetic induction. Power loss also comes from resistance in the coils, causing heat energy to be lost. You can only find out the age of a material, not when it was used. The number of unstable nuclei decreases exponentially with time. A low current prevents greater resistance in the wires and therefore prevents greater energy losses. It can also release additional neutrons which can initiate a chain reaction. Our AS and A-level Physics specifications will help you to inspire students, nurture their passion for the subject and lay the foundations for further study and the workplace. What will I study? can be shown by the gradient of a flux linkage against time graph. 1 Measurements and their errors (coming soon) 2 Particles and radiation 3 Waves. The continuously changing flux causes currents called. Physics (7407, 7408) Notes. This guide is not a comprehensive set of teaching notes. The material on this website is written to support the AS and A level lessons that I teach. Generators and dynamos are examples of applications of Faraday’s and Lenz’s laws. is done in stages, with power transferred from overhead lines to underground wires. A very small minority of the particles deflected at an angle of less than 90°. 0 Comments. Electrons can be diffracted by the nuclei of atoms. The moderator is used to slow down the neutrons released from the fission reactions and turn them into thermal neutrons so that they can be absorbed by the nuclei. Contents Page Moreover, we have taken convenience to another level now. They are written for the AQA exam board but should still be useful for all other exam boards, including Edexcel, and OCR A and B. The decreasing of the p.d.

Practical work is at the heart of all good science teaching, and the required practical activities will give students the opportunity to embed their skills and knowledge. Forces and Motion. Seneca is the best online revision app. The number of particles was measured at different angles to the gold foil. The content of the AQA Physics A-Level is split into core topics that everyone must take and optional topics that AQA introduced in order to cater to students’ varying interests in the different branches of physics. The option modules for A-level Physics enable students to focus on topic areas that really engage them. Activity: the number of atoms that decay per second (Bq).

Sound waves, seismic waves and waves on strings are known as mechanical waves. 4.1 Waves and vibrations Types of waves: Waves that pass through a substance are vibrations which pass through that substance. Energy is released during fission because the smaller nuclei have a smaller total mass than the original nucleus, resulting in a mass defect and therefore, a release of energy.
