A bomber plane is moving horizontally with a speed of 600 m/s and a bomb released from it strikes the ground in 10 sec. What is the measure of angle at which the bomb strikes the ground? (g = 10 m/s²)

A body is dropped from height 'h'. If the coefficient of restitution is 'e', calculate the height achieved (h₁) after one bounce.

To express the size of a molecule and an atom, a small size unit called the ____ is used.

One femtometre is equivalent to

Which of the following units denotes the dimensions [ML²/Q²], where 'Q' represents the electric charge?

A solid sphere (M) attached to a massless spring (K) can roll without slipping along a horizontal surface. If the system is released after an initial stretch, the time period will be–

A transverse sinusoidal wave moves along a string in the positive x-direction at a speed of 10 cms^-1.

The wavelength of the wave is 0.5 m and its amplitude is 10 cm. At a particular time t, the snapshot of the wave is shown in the figure. What is the velocity of point P when its displacement is 5 cm?

Four thin metal rods, each of mass M and length L, are welded to form a square ABCD as shown in the figure. What is the moment of inertia of the composite structure about a line which bisects rods AB and CD and is perpendicular to the plane of the structure?

A uniform cylindrical rod of mass 'M' and length 'L' is rotating with an angular speed 'ω'. The axis of rotation is perpendicular to its axis of symmetry and passes through one of its end faces. If the room temperature increases by 't' and the coefficient of linear expansion of the rod is 'α', the magnitude of change in its angular speed is
