    Calculate Energy Prod. in Sun, Hydrogen Consumption & Burning Time

    The radiation flux from the sun at the top of the Earth's atmosphere is 0.139 J cm-2 s-1 at normal incidence. The Earth is 1.50x108 km from the sun. Calculate: (a) the energy production in the sun in MeV/s (b) the rate of hydrogen consumption in g/s (c) how long hydrogen-burning can continue...

    Photoelectric effect and Rydberg's formula

    A peak in the energy spectrum is seen at 134.2 keV when using a germanium detector. In coincidence with this, an x-ray corresponding to the 2s to 1s electronic transition in germanium is detected. Find the energy (in keV) of the gamma ray that ejected the electron. Use Rydberg's formula for...

    Kinetic Energy of Ion accelerated across potential difference

    An ion of 64Zn30+ with an initial kinetic energy of 9.88 keV is accelerated across a potential difference of 277 Volts. What is its kinetic energy after acceleration (in keV)?
