Longitudinal strain is possible in
Light appears to travel in a straight line, because
If a person with a spring balance and a body hanging from it goes up and up in an aeroplane, then the reading of the weight of the body as indicated by the spring balance, will
Heat travels through vaccum by
Gravitational mass is proportional to gravitational
The ratio $C_p /C_v$ for a diatomic gas is more than that for a monotomic gas. The molecules of a monotomic gas have more degree of freedom than those of a diatomic gas.
Newton?? rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is bright. This is because the reflections in these cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.
In series LCR circuit, the resonance occurs at one frequency only. At resonance the inductive reactance is equal and opposite to the capacitive reactance.
According to Maxwell?? hypothesis, a changing electric field gives rise to
A spring $40 \,mm$ long is stretched by the application of a force. If $10 \,N$ force required to stretch the spring through $1 \,mm$, then work done in stretching the spring through $40\, mm$, is
A quanity of heat required to change the unit mass of a solid substance, from solid state to liquid state, while the temperature remains constant, is known as
If the kinetic energy of a body becomes four times of its initial value, then new momentum will
The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as
The dimensions of angular velocity, is
If the equation for the displacement of a particle moving on a circular path is given by $(\theta)=$ $2 t^{3}+0.5$ where $\theta$ is in radians and $t$ in seconds, then the angular velocity of the particleat $t = 2\, sec$, is
A bullet is fired from a rifle. If the rifle recoils freely, then the kinetic energy of the rifle, is
The ratio of magnitudes of average velocity to average speed, is
The value of acceleration due to gravity $'g'$, at earth's surface is $10\, m / s ^{2} .$ Its value at the centre of the earth which is assumed to be sphere of radius $' R'$ and uniform mass density, is
