A particle is moving with a velocity four times the velocity of an electron. If the de Broglie wavelength of the particle is $1.5 \times 10^{-4}$ times the de Broglie wavelength of the electron, then the mass of the particle is (mass of electron $= 9 \times 10^{-31} \, {kg}$):

The electric field between the plates of a parallel plate capacitor changes at the rate of $4.5 \times 10^{7} \, {V/m/s}$. If the plates of the capacitor are circular with radius 2 cm, then the displacement current inside the capacitor is:

The device constructed based on the laws of electromagnetic induction is:

The magnetic force per unit length acting on a wire carrying a current of $4\sqrt{3}$ A and making an angle of $60^\circ$ with the direction of a uniform magnetic field of 200 mT is:

The magnetic field at a point $ P $ at a distance of 2 cm from a long straight wire of diameter 0.5 mm carrying a current of 1 A is $ B $. If the diameter of the wire is doubled without changing the current, the magnetic field at the same point $ P $ is:

The distance travelled by an electron in time of $3\,{ns}$ when accelerated from rest in an electric field of $0.9 \times 10^4\, {N/C}$ is: \[ {(mass of electron } = 9 \times 10^{-31} { kg, charge } = 1.6 \times 10^{-19} { C)} \]

To decrease the capacitance of a parallel plate capacitor:

As shown in the figure, a rod AB of length 5 cm is placed in front of a convex mirror on its principal axis. If the radius of curvature of the mirror is 20 cm, then the length of the image of the rod is:

A closed vessel contains a gas at a pressure $P$. If 50% of the mass of the gas is removed and rms speed of the gas molecules is increased by 20%, then the pressure of the remaining gas is

The thermodynamic process in which the change in internal energy of the system becomes zero is

When a polyatomic gas is heated at constant pressure, the percentage of heat given to the gas that is converted into external work is
(Ratio of the specific heat capacities of the gas = $\frac{4}{3}$)

A solid sphere at a temperature of 400 K radiates a power $P$. If the radius of the sphere is halved and its absolute temperature is doubled, then the power radiated by it is

The work to be done to blow a soap bubble of radius $3 \times 10^{-3}$ m is nearly
(Surface tension of soap solution = $20 \times 10^{-3}$ N m$^{-1}$)

If a body is projected from the surface of the earth with a velocity of $\sqrt{5}V_e$, then the velocity of the body when it escapes from the gravitational influence of the earth is
(Escape velocity of a body from the surface of the earth, $V_e = 11.2$ km s$^{-1}$)

If $T$ is the time period of a simple pendulum, then at a time $\frac{T}{6}$ the pendulum passes its mean position

As shown in the figure, if a solid sphere of mass $M$ rolling with a speed $v$ on a horizontal surface strikes a spring of force constant $k$, then the maximum compression of the spring is

The upper end of a wire of length 5 m is fixed to the ceiling and a 20 kg mass is attached at its lower end. If the wire makes an angle $60^\circ$ with the horizontal, then the moment of force due to gravity to the upper end of the wire is: (Acceleration due to gravity = 10 m s$^{-2}$)

A machine gun with power 15 kW can fire 360 bullets per minute. If the mass of each bullet is 5 g, then the velocity of the bullets is:

D) $p^{53}$ protein	II. Guardian angel of genome

Tall T-wave of ECG indicates

This hominoid is more ape like.

Assertion (A): Genetic drift tends to reduce the amount of genetic variation within the population.
Reason (R): In genetic drift alleles with low frequencies are removed in a population.
