Nuclei Test - 6...

A nucleus of mass M +$\triangle m$ is at rest and decays into daughter nucleus of equal mass $\dfrac { M }{ 2 }$ each 
speed of light is c 
The speed of daughter nuclei is:-

In the nuclear reaction, $X\left( {n,\alpha } \right){ \to _3}L{i^7}$ which of the following option is correct?

The binding energies per nucleon of deutron and $\alpha - particles$ are $X_1$ and $X_2$ respectively. The energy released in the following reaction will be: $1{H}^2 + 1{H}^2 = 2{He}^4 + Q$

Binding energy of deuterium is 2.23 MeV, then its mass defect in a.m.u. is:
 The value of energy for $_1H^2, _2He^4, _{26}Fe^{56}, _{92}U^{235}$. 

The binding energy of $\alpha$-particle $\begin{array} { l } { 4 } \\ { 2 } \end{array}He$ is $7.047$ $MeV$ per nucleon and the binding energy of deutron $\begin{array} { l } { 2} \\ { 1 } \end{array}H$ is $1.112$ $MeV$ per nucleon. Then in the fusion reaction $_ { 1 } ^ { 2 } H + _ { 1 } ^ { 2 } H \rightarrow _ { 2 } ^ { 4 } H e + Q$, the energy $Q$ released is 

Two radioactive nuclei P and Q in a given sample decay into a stable nucleus R. At time t = 0, number of P species are $4 N_o$ and that of Q are $N_o$. Half-life of P (for conversion to R) is 1 minute where as that of Q is 2 minutes. Initially there are no nuclei of R present in the sample. When number of nuclei of P and Q are equal, the number of nuclei of
R present in the sample would be :-

The binding energy per nucleon for $O^{16}$ and $O^{17}$ are respectively 7.99 MeV and 7.95 MeV. The energy required to remove one neutron from the nucleus of $O^{17}$ expressed in MeV is

A nucleus of atomic mass M emits a gamma ray photon of frequency v. then 

If the nucleus is seen as a cubical box of length $10^{-14}\ m$, then compute the minimum energy of a nucleon confined to the nucleus. Mass of nucleon=$1.6\times 10^{-27}\ Kg$

Ratio of binding energy of a satellite revolving few metre above the earth's surface and same satellite rest on earth is
