well just assuming the spacecraft is traveling very close to the surface of the eart at 0.9c, would there be change in the reading on the scales of the weight of the person in the spacecraft as seen by the stationary observer? obviously the person in the spacecraft would not experience...

Hey guys, on http://www.chemistryhelp.net/basic-chemistry/amphiprotic-substances I saw that HSO4- (hydrogen sulfate) is a amphiprotic (can accept and donate H+ ions) and therefore acts as a base or acid (amphoteric) why is this so? Isn't H2SO4 (sulfuric acid) a strong acid and so its...

Hey guys, i was just wondering what would happen if a person was on a spacecraft traveling at 0.9c was standing on a set of scales that measured his mass, went past a stationary observer. Would the stationary observer see the reading on the scales increase due to mass dilation? I asked a...
