Answer:
L= 12 light years
Explanation:
for length dilation we use the formula

now calculating Lo
Lo = 12.5×365×24×3600×3×10^8
= 1.183×10^17 m
now putting the values of v and Lo in the above equation we get

= 1.136×10^17 m
L=
m
so L= 12 light years
Answer:

Explanation:
Electric field in a given region is given by equation

as we know the relation between electric field and potential difference is given as

so here we have


here we know that
and 
so we will have

so we will have

yes it does it because the material cause it to refract and the stronger it is the more it will refract
The answer is "Three".
