Raising more livestock is helps the environment through their feces, but it doesn't help global warming trends. Building more schools does not even reduce global warming trends at all. It may do more damage if machines that produces pollution are used during the process of building.
Hope this helps!!!
Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)
Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.
Hope this is what you wanted.
