NEET 2015 Code A - Mock Test

The heart of a man pumps $5\text{litres}$ of blood through the arteries per minute at a pressure of $150\text{mm}$ of mercury. If the density of mercury be $13.6\times 10^3{\text{kg/m}}^3$ and $g=10{\text{m s}}^2$ then the power of heart in watt is:

A proton and an alpha particle both enter a region of uniform magnetic field $B$, moving at right angles to the field $B$. If the radius of circular orbits for both the particles is equal and the kinetic energy acquired by proton is $1\text{MeV}$, the energy acquired by the alpha particle will be:

The input signal given to a CE amplifier having a voltage gain of $150$ is $V_i=2\cos (15t+\frac{\pi }{3})$. The corresponding output signal will be:

If dimensions of critical velocity $v_c$ of a liquid flowing through a tube are expressed as $[{\eta }^x{\rho }^y{r}^z]$, where $\eta ,\rho$ and $r$ are the coefficient of viscosity, density of liquid and radius of the tube respectively, then the values of $x,y$ and $z$ are:

A circuit contains an ammeter, a battery of $30\text{V}$ and a resistance $40.8\Omega$ all connected in series. If the ammeter has a coil of resistance $480\Omega$ and a shunt of $20\Omega$, the reading in the ammeter will be:
