Answer:
(i) The speed of light could then be found by dividing the diameter of the Earth's orbit by the time difference. The Dutch scientist Christiaan Huygens, who first did the arithmetic, found a value for the speed of light equivalent to 131,000 miles per second. The correct value is 186,000 miles per second.
(ii) pace that is completely empty of all substances, including air or other gases.
(iii) Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). ... Water covers 71% of the Earth's surface, mostly in seas and oceans.
