Strangely, âposhliâ (which means âletâs goâ or âletâs head outâ in Russian) is actually the past tense of the verb meaning âTo head off on foot.â In other words, âposhliâ literally means, âWe (or they) headed off on foot.â How can a word which is in the past tense indicate the desire to head off somewhere now?
The Hill sphere, or gravitational sphere of influence, of Earth is about 1.5 Gm or 1,500,000 km in radius. This is the maximum distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets.
ANSWER: The surface area of the earth is about 200 million square miles and about 70% is water, so 140 million square miles; that is about 3.6x1014 m2. The diameter of a water molecule is about 3 angstroms=3x10-10 m. So the volume is 11x104 m3 which is about 30 million gallons.
