A black body, at a temperature of $227^{\circ} C$, radiates heat at a rate of $20 \,cal\, m ^{-2} s ^{-1} .$ When its temperature is raised to $727^{\circ} C$, the heat radiated by it in $cal \,m ^{-2} s ^{-1}$ will be closest to
A double slit experiment is performed with light of wavelength $500\, nm$. A thin film of thickness $2\, \mu m$ and refractive index $1.5$ is introduced in the path of the upper beam. The location of the central maximum will
The motion of planets in the solar system is an example of conservation of
A beam of charged particles is employed in the treatment of cancer. Charged particles on passing through a material medium lose their energy by causing ionization of the atoms along their path.
The difference in the lengths of a mean solar day and a sidereal day is about
The resistivity of a semiconductor increases with temperature. The atoms of a semiconductor vibrate with large amplitude at higher temperatures there by increasing its resistivity.
A rectangular loop carrying a current $i_{1}$, is situated near a long straight wire carrying a steady current $i_{2}$. The wire is parallel to one of the sides of the loop and is in the plane of the loop as shown in the figure. Then the current loop will
In short wave communication, waves of which of the following frequencies will be reflected back by the ionospheric layer having electron density $10^{11}$ per $m ^{3}$ ?
In an experiment to find the focal length of a concave mirror a graph is drawn between the magnitudcs of $u$ and $v$. The graph looks like
In an ideal parallel $LC$ circuit, the capacitor is charged by connecting it to a $DC$ source which is then disconnected. The current in the circuit
What is the path difference for destructive interference?
The Cauchy's dispersion formula is
An electron having charge $e$ and mass $m$ is moving in a uniform electric field $E .$ Its acceleration will be
Brilliance of diamond is due to
Velocity of light is equal to
The magnetic needle of a tangent galvanometer is deflected at an angle $30^{\circ}$ due to a magnet. The horizontal component of earth's magnetic field $0.34$ $\times 10^{-4} T$ is along the plane of the coil. The magnetic intensity is
The coefficient of mutual inductance, when magnetic flux changes by $2 \times 10^{-2} Wb$ and current changes by $0.01 A$ is

Kepler's second law is based on
Golden view of sea shell is due to
At the uppermost point of a projectile, its velocity and acceleration are at an angle of
Woolen clothes keep the body warm in winter. Air is a bad conductor of heat.
Stress is the internal force per unit area of a body. Rubber is more elastic than steel.
S.I. units are logical and coherent. S.I. system of units is a rationalised system.
