The mass number of an atom is 15 and its atomic number is 7. Now, this atom absorbs an \( \alpha \)-particle and emits a proton. What will be the mass number of changed atom?
Binding energy per nucleon plot against the mass number for stable nuclei is shown in the figure. Which curve is correct?
The nuclear reaction \(_1\mathrm{H}^1 + _1\mathrm{H}^1 \rightarrow _2\mathrm{He}^4\) (mass of deuteron = 2.0141 amu and of He = 4.0024 amu) is
The binding energy per nucleon is maximum in the case of
The mass defect in a particular nuclear reaction is \(0.3 \, \text{g}\). The amount of energy liberated in kilowatt-hours is (velocity of light \( = 3 \times 10^8 \, \text{m/s}\)).
Two sources give an interference pattern observed on a screen distance D away. The fringe width is 2W. If D is doubled, the fringe width will:
Nuclear reactor in which U-235 is used as fuel uses 2 kg of U-235 in 30 days. Then, power output of the reactor will be (given energy released per fission = 185 MeV):
A mass m is placed on a wedge (triangular block) of mass M. The wedge moves on a smooth horizontal surface. What should be the force F applied on the wedge to the right, so that m remains stationary with respect to wedge? (Ignore any friction)

The correct relation between \(\alpha\) and \(\beta\) in a transistor is
The half-life of the isotope \( ^{11}\text{Na}^{24} \) is 15 h. How much time does it take for \( \frac{7}{8} \) of a sample of this isotope to decay?
As a result of radioactive decay, \( ^{238}U \) is converted into \( ^{234}Pa \). The particles emitted during this decay are:
A body of mass x kg is moving with a velocity of $100~\text{m s}^{-1}$. Its de-Broglie wavelength is $6.62\times10^{-35}$ m. Hence, x is ($h=6.62\times10^{-34}$ Js)
