Answer:
Explanation:
Given:
- depth of fish,
- angle of incidence,
- refractive index of water,
<u>Apparent distance from the normal projection at the bottom of entrance at air-water surface to the fish:</u>
<u>Now according to Snell's Law:</u>
<u>Now the actual distance of the fish from the bottom surface at the normal:</u>
<u>Now distance between bullet hole and fish</u>:

Pangaea
Explanation:
The Earth's crust is not one solid block but is made of different segments called tectonic plates. At one point it started to break apart. The land mass was present around the Paleozoic and Mesozoic eras. This land mass was called Pangaea
