    Atomic nuclei consist of protons and neutrons‚ which have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the

    12. Outline the symbol’s box in dark green if it is RADIOACTIVE in its most common form.    Notes The nucleus The nucleus is at the center of the atom and contains the protons and neutrons. Protons and neutrons are collectively known as nucleons. Virtually all the mass of the atom is concentrated in the nucleus‚ because the electrons weigh so little. Working out the numbers of protons and neutrons No of protons = ATOMIC NUMBER of the atom The atomic number is also given the more descriptive

    SCI215 M4-Assignment 1: Discussion—The Promises and Perils of Nuclear Power Nuclear power refers to the generation of electrical energy by controlled nuclear reactions. These reactions produce heat‚ which in turn creates steam that runs the generators to produce electricity. Approx. 1/8 of the electricity worldwide generated comes from nuclear energy. In this task‚ you will analyze the use of nuclear energy as a resource energy. * Discuss the scientific and technical concepts related to

    the question remains whether these mathematical manipulations actually correspond to the spatial deformations in real nuclei. Problems with the shell model have led some to propose realistic two-body and three-body nuclear force effects involving nucleon clusters and then build the nucleus on this basis. Two such cluster models are the Close-Packed Spheron Model of Linus Pauling and the 2D Ising Model of MacGregor.[10] Consistency between models[edit] Main article: Nuclear structure[->0] As with

    uranium atom are split by the energy known as nuclear binding energy. Protons and neutrons binding energies are the energies required to release them from the nucleus. In binding energy‚ the mass the actual mass is always less than the mass of the nucleons (Protons + Neutrons) combined due to the energy released when the nucleus is formed. This is known as mass defect. So in this case‚ it release energy in the form of heat in nuclear fission to heat up

    Basic Physics Content with Answers 1. In the absence of air resistance‚ a ball of mass m is tossed upward to reach a height of 20 m. At the 10m position‚ half way up‚ the net force on the ball is A. 2mg. B. mg. C. mg/2. D. mg/4. B is correct‚ as a vector diagram would show. Other choices show carelessness or confusion between force and speed‚ and what constant acceleration means. 2. When you drop a ball it accelerates downward at 9.8 m/s2. If you instead throw it downward‚ then its acceleration
