Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
S=ut+a(t^2)/2 = a(t^2)/2 [since u=0] =(v/t)*(t^2)/2 [since a=(v-u)/t=v/t] =vt/2 =180*{25/(60*60)}/2 km = 0.625 km =625 m

Answer:
C) 24.4°
Explanation:
let nd = 2.419 be the index of refraction of diamond and na = 1.0 be the index of refraction of air and ∅c be the critical angle.
according to Snell's Law:
sin(∅c) = na/nd
sin(∅c) = (1.0)/(2.419)
∅c = 24.4°
