The velocity of light in glass whose refractive index w.r.t, air is 1.5 is 2 xx 10^(8) m//s . In a certain liquid, the velocity of light is found to be 2.5 xx 10^(8) m//s . The refractive index of the liquid w.r.t. air is

The displacement of a particle from its mean position (in mean is given by y = 0.2 sin(10pi t + 1.5 pi) cos (10 pi t+ 1.5 pi) . The motion but not S.H.M.

1f a person makes a profit of 10% on one-fourth of the quantity sold and a loss of 20% on the rest, then what is the average percent profit or loss? 11. 25 % los s b. 11. 75 % p rofi t c. 12. 5 % p rofi t d. 12. 5 % los s

Find the average velocity of motion specified by the formula s = (t^(2) - 5t + 2) m from t_(1) = 5 sec to t_(2) =15 sec.

In a Young's double-slit experiment set up, source S of wavelength 6000 Å illuminates two slits S_(1) and S_(2) which act two coherent sources. The sources S oscillates about its shown position according to the eqation y = 1 + cos pi t , where y is in millimeter and t in second. At t = 1 s, a slab of thickness 2 xx 10^(-3) mm an refractive index 1.5 is placed just in front of S_(1) . The central maximum is formed at
