Nuclear Fission The Basic Process

Nuclear Fission The Basic Process In 1932 English physicist lames Chadwick~~ discovered the neutron. A few years I~ Enrico Fermi in Rome found hat when various elements are bombarded by neutrons, new radioactive elements are produced. Fermi had predicted that.the neulrOll, being , w~ be a useful nuclear projectile; unlike the proton or the alpha par. ticle, it …

Flux

Flux Suppose that as in  you aim a wide air stream of uniform velocity small square loop of area A Let  represent the volume ate (volume per unit time) at which air flows through the loop This rate depends on the angle between  and the plane of the loop If  is perpendicular to the plane the rate  is equal to …

Forced Oscillations and Resonance

Forced Oscillations and Resonance A person swinging in a swing without anyone pushing it is an example of  oscillation. However if someone pushes the swing periodically the swing forced or driven oscillations Two angular frequencies are associated with a system undergoing driven osciIlations (I) the natural angular frequency w of the system which is the angular frequency …
