11. A planet is revolving around the sun in an elliptical orbit. The mass of planet is m, angular momentum of planet about sun is L, and length of semi major axis is a and eccentricity are e. Time period of revolution of planet is given by (a) T= 2mma1+6 L (c) T = 2mma1-82 L (b) T = ma1-2 L (d) T = mma21-2 BL (U) of the 12. An ideal gas undergoes a thermodynamic process in which internal energy gas depends on pressure (P) of the gas as = ap4, where a is a positive constant. Assuming gas to be monoatomic, the molar heat capacity of the gas for given process will be (a) 3R 3/ shiksha 13. A vertical cylindrical vessel contains a half litre of water having column height of 60 cm. If the density and bulk modulus of water are 103 kg m and 2 x 10 N m respectively, then the elastic deformation potential energy (approximately) of water, is (a) 1.8 j (c) 2.1 J (b) 1.5 J (d) 2.4 J 14. For an SHM oscillator, the amplitude is 5 cm and its time period is 4 seconds. The minimum time taken by the particle to pass between points which are at distances 4 cm and 3 cm from the centre of oscillation on the same side of it will be (a) 0.13 second (c) 0.26 second (b) 0.18 second (d) 0.35 second 11.
