A student performed analysis of aliphatic organic compound X which on analysis gave C = 61.01%, H = 15.25%, N = 23.74%. This compound, on treatment with HNO2/H2O produced another compound Y which did not contain any nitrogen atom. However, the compound Y upon controlled oxidation produced another compound Z that responded to iodoform test. The structure of X is

A fly wheel having mass 3 kg and radius 5 m is free to rotate about a horizontal axis. A string having negligible mass is wound around the wheel and the loose end of the string is connected to 3 kg mass. The mass is kept at rest initially and released. Kinetic energy of the wheel when the mass descends by 3 m is

A beam of light consisting of wavelengths 650 nm and 550 nm illuminates the Young’s double slits with separation of 2 mm such that the interference fringes are formed on a screen, placed at a distance of 1.2 m from the slits. The least distance of a point from the central maximum, where the bright fringes due to both the wavelengths coincide, is ______ × 10⁻⁵ m.

A particle starts moving from time � and its coordinate is given as � A. The particle returns to its original position (origin) 0.866 units later B. The particle is 1 unit away from origin at its turning point C. Acceleration of the particle is non-negative D. The particle is 0.5 units away from origin at its turning point E. Particle never turns back as acceleration is non-negative
