Can Massive Ice Comets vaporize in the thermosphere before reaching the lower layers of atmosphere.
If so, and that vaporized H20 condenses again to fall to the Earth's surface, would that rainfall , fall slower than the velocity it has when it was part of an Icy Comet that hit the thermosphere.
IN OTHER WORDS, would the rainfall cause less kinetic energy than if was still a solid material speeding to the Earth's surface.

My friend told me that lightning does more damage when the ground near you is striked then when you are striked. I was wondering exactly why this was. I was also wondering, if it makes a difference to the effects on your body if you where on super turf ( fake grass) compared to real grass dirt or concrete. Also if you where holding a metal object when the ground near was struck by lightning what would happen?

2 airplanes, A & B are flying at the same altitude in the direction N30˚E and N10˚W. when B is 10km to the east of A, the pilots of both airplanes found that their planes are in the path of collision. If the speed of A is 500km h-1, find the speed of B. Give your answer to 3 significant figures. If at that point in time, B changes direction to N45˚W without changing its speed, find the closest distance between A & B.
(ANS:440 km h-1, 2.13 km)
