Yes a period can do thios If it is this heavy then try not to go to school or work when it is this heavy because it can also be very smelly.
It is different for everybody. Some do some dont. So I guess it is considered normal.
Not it is normal, so there is nothing to be worried about (:
Its fine so long as he/she is not on the website for long periods of time
Yes, that can be normal. Periods average 3-5 days in duration and cycles average 28 days. But, if your periods are so heavy that they become a nuisance, such as having to change your tampon/pad every two hours or even less, you might want to mention this to your doctor if this is the case.
13 is a prime number so the only factors are 1 and itself.
Go to see your doctor - there's medication to make you less likely to throw up, painkillers for the cramps, and also medication to reduce your flow if your periods are so heavy it causes problems for you.
13 is a prime so its only factors are 1 and 13. 13 is NOT a factor of 9, so the only common factors of the two numbers is 1.
if they have started their periods then yes, but I'm a bloke so I'm not really an expert

Only 1 and 13 so it's a prime number
Every individual is different. While some women experience long periods with heavy flow, others experience short periods with mild flow to only spotting. This is normal so long as it has always been this way. If this is a new occurrence, I would recommend consulting your family physicians as it could be an indicator to several things (one being malnutrition, especially if you are an athlete). If this is your normal cycle however, consider yourself lucky to have a shorter period.
