Question:
I have some questions about speed. How many m.p.h.'s per hour does a torpedo go? And what about twisters?


Replies:
Do you want to know about a torpedo or a tornado? A torpedo is a missile sent underwater from a ship to destroy another ship and the speed is probably not too high - maybe 100 mph or so. A tornado (which I think is the same thing as a "twister") can have internal wind speeds of up to 300 miles per hour (from vague recollections, not from an authoritative source), but they move along the ground much slower - maybe 50 mph or so? Hurricanes are much bigger, but their wind speeds max out at around 130 mph I think. It is pretty amazing that something as simple as air can have such complicated behaviors!
