ANSWER:
Solution 14Q:
Step 1 of 2:-
Here we can use the ratio between the difference in distance from the two sides of earth and the distance between sun and earth .
This will lead to:
And again, the ratio between the difference in distance from the two sides of earth and the distance between moon and earth will be,
.
Where is the distance between earth and sun.
is the distance between earth and moon.
