One mole of a monoatomic ideal gas undergoes the process $A \to B$ as shown in the given $P$–$V$ diagram. The specific heat capacity in the process is
A magnetic dipole in a constant magnetic field has
A parallel plate capacitor is made of two square plates of side $a$, separated by a distance $d$ ($d \ll a$). The lower triangular portion is filled with a dielectric of dielectric constant $K$, as shown in the figure. The capacitance of this capacitor is
A particle executing SHM along a straight line has zero velocity at points $A$ and $B$ whose distances from $O$ on the same direction $OAB$ are $a$ and $b$ respectively. If the velocity at the midpoint between $A$ and $B$ is $v$, then its time period is
A shell is fired from a fixed artillery gun with an initial speed $u$ such that it hits the target on the ground at a distance $R$ from it. If $t_1$ and $t_2$ are the values of the time taken by it to hit the target in two possible ways, the product $t_1t_2$ is
The frequency of a tuning fork P is $a%$ less than a standard fork A. The frequency of another fork Q is $b%$ greater than that of A. When P and Q are sounded together, $x$ beats are produced in one second. The frequency of the standard fork is (in Hz)
A metallic wire of density $d$ floats horizontally in water. The maximum radius of the wire so that the wire may not sink will be (surface tension of water = $T$)
A tank full of water has a small hole at the bottom. If one-fourth of the tank is emptied in $t_1$ seconds and the remaining three-fourths of the tank is emptied in $t_2$ seconds, then the ratio $t_1/t_2$ is
A block of mass $m$ is kept on a platform which starts from rest with constant acceleration $\dfrac{g}{2}$ upward, as shown in the figure. Work done by the normal reaction on the block in time $t$ is:
Expression for time in terms of $G$ (universal gravitational constant), $h$ (Planck constant) and $c$ (speed of light) is proportional to:
In a car race on a straight road, car A takes a time $t$ less than car B at the finish and passes the finishing point with a speed $v$ more than that of car B. Both the cars start from rest and travel with constant accelerations $a_1$ and $a_2$ respectively. Then $v$ is equal to
