Consider the following statements-
IN a stationary wave
1. All the particles perform simple harmonic motion with a frequency which is four times that of the two component waves.
2. Particles on the opposite sides of a node vibrate with a phase difference of 
3. The amplitude of vibration of a particle at an antinode is equal to that of either component wave.
4. All the particles between two adjacent nodes vibrate in phase.
Of these statements-

A wheel of M. I.(Moment of inertia)  is making 10 revolution per second. It is stopped in 20 Second. Then angular retardation is

The moment of inertia of a body about a given axis is 1.2 kg-m². Initially, the body is at rest. In order to produce a rotational KE of 1500 J, an angular acceleration of 25 rad/s² must be applied about that axis for a duration of :

One mole of an ideal gas expands at a constant temperature of 300 K from an initial volume of 10 litres to a final volume of 20 litres. The work done (in J) in expanding the gas is
(R = 8.31 J/mole-K) (log 2 = 0.3010)

Time taken (in s) by a 836 W heater to heat one litre of water from 10°C to 40°C is :-

The escape velocity from a planet is v₀. The escape velocity from a planet having twice the radius but same density is nv₀ then n is :-

For an EMwaves, E = E₀ sin (12 × 10⁶ [z – 2 × 10⁸t]) In a medium, it's refractive index is P/2 then P is
