Male dragonflies scoop out the inside of the female before mating to get rid of any other sperm. Female cockroaches get less picky about their choice of mate as they get older. I know far too much about insect sex.

Actually immediately because Earth is a curved surface, the distance it travels before it hits' the ground is affected by how much force is behind it but it will still hit the ground at the same time so if you fired a two perfectly level handgun and rifle fired from the same height the bullet won't land at the same spot but they will land at the same time.deanoxxx said:
Their is some debate and my algebra is no where near good enough to make a model but I have a link to the discussions on yahoo;

and some math here:

A fired bullet (along with the dropped bullet) has no lift (upward force) acting on it. So the only force acting on the height the fired bullet or the dropped bullet is gravity. Since they have an equal amount of downward force (gravity) acting on them and no upward force (lift) acting on them, the total force acting on each bullet is equal. This means that they will take the same amount of time to hit the ground.
To toss a bit of math into the explanation...
t = sqrt(2x/g)
t = time
sqrt = square root
x = initial height
g = force of gravity
Since x and g are the same for both a fired bullet and a dropped bullet, t will be equal as well.
With regards to air resistance, yes it will affect things and no they will not hit the ground at EXACTLY the same time. But, the difference will be tiny since the starting height of this experiment is (at least my mind) about 5 feet. I can't say exactly how much longer it would take a horizontal bullet to fall that distance versus a tumbling one, but I know it's not more than .1 seconds or so.
(I might get strung up for this one.) I think the intent of the physics teacher saying that they hit the ground at the same time is just to illustrate that even though the two bullets seem vastly different, the forces acting on them are the same.
I've had to eat an onion raw before in a bet that I lost, they do taste exactly the same. In that case, you'd think it was an easy win, but the bet also ruled that I had to eat the onion (which was bigger than my fist) in under two minutes or all my cousins each get a turn to beat me up.afaceforradio said:

Did you Know?
That carrots used to be a wider variety of colors, white being the most common, and were selectively bred to become orange?
That a man leading a five-hundred man scouting army, forced another man, whom was his rival, to retreat by simply playing a musical instrument?

Is that because it's in hotel rooms? If so, I believe they're "complimentary" ;Dafaceforradio said:

Cetaceans, inch for inch, have the biggest dorks. Just so you know, a dork is the actual name for a whale?s penis. So the next time a person calls you a dork, they?re calling you a whale penis. At any rate, the blue whale is known to have the largest penis. It is also capable of maneuvering on its own while trying to reach the female?s vagina. The largest ever measured on a specimen reached 8 feet.
did you know that one of hitlers scientists injected food coloring into peaoples eyes to change their eye color
