6.4 kJ of energy per minute is produced in a nuclear reactor. Find out the number of fissions that take place in it in one hour. If the energy released per fission is `3.2xx10^-11J`.

Suppose India had a target of producing by 2020 AD, 200,000 MW of electric power, ten percent of which was to be obtained from nuclear power plants. Suppose we are given that, on an average, the efficiency of utilization (i.e. conversion to electric energy) of thermal energy produced in a reactor was 25%. How much amount of fissionable uranium would our country need per year by 2020? Take the heat energy per fission of "^235U to be about 200MeV.

In which case the energy released per nuclear is more: In fission or fusion?

An iron smaple having mass 8.4 kg is repeatedly taken over cycles of magnetisation and demagnetisation at a frequency of 50Hz. It is found that energy of 3.2 J is dissipated as heat in the sample in 30 minutes. If the denstiy of iron is 7200 kg m^-3 , calculate the value of energy dissipated per unit volume per cycle in the iron sample.

Calculate the energy released by the fission of 1.0 kg of "^235U in a fission reactor.

Select the correct statement(s) : a) In the reaction ._(92)^(235)U+_(0)^(1)n rarr _(56)^(140)Ba +2_(0)^(1)n +x, x is _(36)^(94)Kr b) In the reaction ._(11)^(23)Na +z rarr _(12)^(23)Mg +_(0)^(1)n, the bombarding particle z is deuteron c) Very large amount of energy is produced during nuclear fusion and nuclear fission d) In a fission reaction , a loss in mass occurs releasing a vast amount of energy

The energy of separationof an of an electron is 30.6eV moving in an orbit of Li^(+2) Find out the number of waves made by the electron in one complete revolution in the orbit

A heavy nucleus P of mass number of 240 and binding energy 7.6 MeV per nucleon splits into two nuclie Q and R of mass numbers 110 and 130 and binding energy per nucleon 8.5 MeV and 8.4 MeV, respectively. Calculate the energy released in the fission.
