Why is it that science teaches us that earth's mountains, canyons, easily recognized puzzle piece separations of continents and tipped stratta we see everywhere across the face of our fair planet all are the result of billions of years of jerky incremental earth movement varying from inches to feet upon the occurence of any one movement? Add the multi-directional movement & collapse caused by those earth quakes, to erosion by winds, water flow, water freezing/thawing, gravitational forces coupled with the sun's heating & night's cooling of our earth's exposed surfaces. Slowly but surely, the sum of those actions, plus the continual bombardment by comets/asteroids,cause those same surfaces of planet Earth's to crack, crumble, explode & tumble about over the eons of her tortured existence. Yet everywhere the lofty cragged peaks of mountain ranges around the globe fail to show the rounded time worn faces we would expect to see from the action of those same unending incremental forces.

A 5.20 gram bullet moving horizontally at 672 m/s strikes a 700 gram block of wood at rest on a smooth frictionless table. The bullet emerges from the block, traveling in the same direction at 428 m/s. What is the speed of the block after the bullet emerges? How much kinetic energy is converted to other forms of energy during this process?

thanks

Light leaving earth today would reach it after 4.6 years. If I were to reach that star faster than light; for example right now then would I be able to see myself 4.6 years younger?????? And how about i reach a star of my age right now? would i get to see my own birth???

I understand that a particle /linear accerator would be the logical source supplying the energetic, free electrons to the LASER cavity, and that super-cooled, super-conducting magnets (like used in an accelerator or magnetic resonance imaging system) can be used as "wigglers" to tune the wavelength of the emitted photons, but how in "Zues' name" do the electrons that were once free and energetic get recycled into the particle accerator to be reenergized? How does one avoid destroying the mirrors by the tremendous energy and "hot spots"?

I have recently been tracking info about Aircraft Maintainence Engineering and have found a mail ID that could be useful if you need to get into a college where admission for AME is on. It's "mm2mails@yahoo.co.uk". So if you are interested then mail your biodata or your Class XII marks.
This is by far the latest info I have in hand till now. So anybody with any more info can post it as the answer here.
