(Take g = 9.8 m/s2)

(a) 9.8 m/s
(b) 1 m/s
(c) 0 m/s

(a) 10 W
(b) 20 W
(c) 40 W
(d) 2 W

Q9(NSEJS 2012): Wavelength is(i) The distance traveled by the wave in one period of oscillation of particles in the medium.(ii) The distance between two particles, which are in the same phase.(iii) Half of the distance between two particles, which are in the same phase.The correct definitions are
(a) (i) and (iii)
(b) (i) and (ii)
(c) (i), (ii) and (iii)
(d) (ii) and (iii)

Q10: If we increase the time period of a wave, its frequency will 

(a) decrease
(b) increase
(c) remains same
(d) none of these

Average speeds are:
katrina = 9units/4units   (fastest)
priyanka = 5/9   (slowest)
bipasha = 9/9
karrena = 9/5

1: (b) Katrina
2: (c) Priyanka
3: (b) speed
