Question:

When is a public place in the U.S. (like a store/restaurant) required to have a fire alarm?

Question re-posted because the people answering apparently doesn't know where I'm talking about, which should've been known that it's the U.S. I'm talking about.

Answer:

Lightning in one storm may be positively charged, the object it strikes will be negatively charged therefore attracting the lighting to it. Once the lighting has struck a negatively charged object, that object then becomes positively charged meaning the lightning is no longer attracted to it.
People would say that because generally speaking, lightning doesn't originate from exactly the same source more than once. The nature of lightning is that it's a build-up of elctrical charge which has to try and find the shortest route to the ground. If it doesn't originate from the same source as the previous time, then normally there's a faster route to the ground than the last route it took. However if there's a very tall building surrounded by quite a few that are much smaller (as with the Empire State Building) you might well find that it'll get struck more than once.
Lightning can strike the same place more than once. The first bolt of lightning creates an ionised path through the air. If there is another bolt of lightning which sets off shortly afterwards, it may choose to follow the same path (things tending to follow the path of least resistance). Some time ago when I was a student I saw a time-lapse photograph of 4 different lightning bolts all following the same path to the ground
I'm a GSP fan, but Silva would easily win this fight. St. Pierre became the best welterweight in history by imposing his unique advantages - longer reach, freakish athleticism and strong wrestling (especially with the double leg takedown). Unfortunately, Anderson is able to neutralize all of GSP's strengths with even longer reach and accurate strikes, unpredictable movement and amazing jui jitsu submissions. If the fight were to ever take place (which I am pretty doubtful of), GSP would probably take the same approach that Sonnen did. I think he would be able to take silva down repeatedly; however, similar to Chael's fight, St Pierre would not be able to inflict any serious damage on Anderson. Eventually, Silva would catch GSP on the way in with a big strike or submit him via a guilotine choke. On a random note - Shields vs. GSP is a joke! Jake is going to get annihilated!!!
I'm not sure whether there's some confusion with some of the answers already given. If you are talking about different lightning storms on different occasions then lightning definately can (and has) struck in the same place. As someone has stated previously, the Empire State Building (along with all skyscrapers) actually have lightning rods attached to the roofs as they get struck so often. The Empire State Building itself is struck on average 23 times a year. However if your talking about the same storm, It is extremely unlikely (if not impossible) for lightning to strike in the same place twice. This is because, as someone has also already stated, that electricity is always trying to find the fastest route to earth. Combine that with the fact that the storm (cloud) is constantly moving, means that the route to earth will always change. With tall buildings and lightning rods it is possible however for lightning from the same storm to strike the same place, again the Empire State Building is a good example that has reported to have been struck 8 times in 24 minutes! As for people getting struck by lightning, although highly improbable, people have been known to be struck by lightning not only on different occasions but also during the same storm (they had moved to a different location!) Roy Sullivan held a Guinness World Record after surviving 7 different lightning strikes across 35 year! Hope this helps!
