Answer:
774.8 secs
Explanation:
distance(d)= speed(v)* time(t)
calculate speed:
refractive index = speed of light (c)/ speed of light in medium (v)
1.56 = 3*10^8*v
v=192307692.3 m/s
d = v *t
t = d/v
on substituting values:
t = 774.8 secs
Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.
