Which is the correct order of increasing energy of the listed orbitals in the atom of titanium?
A vernier calipers has 1 mm marks on the main scale. It has 20 equal divisions on the vernier scale which match with 16 main scale divisions. The least count of this vernier calipers is:
If $x = at + bt^2$, where $x$ is the distance travelled by the body in kilometres while $t$ is the time in seconds, then the units of $b$ are
A particle is released from a height $S$ above the surface of the earth. At a certain height, its kinetic energy is three times its potential energy. The height from the earth's surface and the speed of the particle at that instant are respectively:
Which one of the following represents all isoelectronic species?
The pressure on a square plate is measured by measuring the force on the plate and the length of the sides of the plate. If the maximum error in the measurement of force and length are respectively $4\%$ and $2\%$. The maximum error in the measurement of pressure is
Which relation is wrong?
Which two of the following five physical parameters have the same dimensions? (1) energy density (2) refractive index (3) dielectric constant (4) Young's modulus (5) magnetic field
If a diamagnetic substance is brought near the north or the south pole of a bar magnet, it is
An object is thrown along a direction inclined at an angle of $45^\circ$ with the horizontal direction. The horizontal range of the particle is equal to:
The quantities which have the same dimensions as those of solid angle are:
The earth is assumed to be a sphere of radius $R$. A platform is arranged at a height $R$ from the surface of the earth. The escape velocity of a body from this platform is $fv_e$, where $v_e$ is its escape velocity from the surface of the earth. The value of $f$ is:
A body weighs $200 \text{ N}$ on the surface of the earth. How much will it weigh halfway down the centre of the earth?
A small hole of an area of cross-section $2 \text{ mm}^2$ is present near the bottom of a fully filled open tank of height $2 \text{ m}$. Taking $g = 10 \text{ m/s}^2$, the rate of flow of water through the open hole would be nearly:
An infinite number of bodies, each of mass $2 \text{ kg}$ are situated on the $x$-axis at distances $1 \text{ m}, 2 \text{ m}, 4 \text{ m}, 8 \text{ m}, ......$ respectively, from the origin. The resulting gravitational potential due to this system at the origin will be:
If the initial tension on a stretched string is doubled, then the ratio of the initial and final speeds of a transverse wave along the string is:
