Explanation / Answer

14)

resonamce angular frequency w = 1/sqrt(LC)

option (b)

15)

the voltage is proportional to number of turns

V1/V2 = N1/N2

option (a)

++++++++++++

16)

through vacuum c = 1/sqrt(uo*eo)

in medium c' = 1/sqrt(k*uo*km*eo) = c/sqrt(k*Km)

option (b)

18)

at total reflection

angle of refraction r = 90

angle of incidence = theacric

na*sini = nb*sinr

nb/na = sinthetacric
