Isn't it always y, no matter the height?
Hint: No. Ignoring issues of air friction, a falling object will continue to accelerate, so the farther it falls, the faster it will be going when it reaches the ground.
Curses! Physics triumphs over Tep!Intuition yet again!
still y. (9.8 meters per second)
You're thinking of acceleration due to gravity, which is 9.8 meters per secondĀ² (or 9.8 meters per second per second. The first "per second" is the velocity, the second is how much the velocity increases each second.)

Hey, I remembered
something
from physics. I say go, me.
Well, it depends on the object, doesn't it? Some reach terminal velocity. Like cats, falling out of a window. They're safer falling from higher stories, because they reach terminal velocity and have a chance to right themselves before hitting ground.

Yeah. Except the terminal velocity is due to wind friction. Which we're ignoring here (but I suppose ignoring wind friction would make the question less intuitive.)
Anyway, I'm gonna start answering the questions. What will take more time is explaining the answers.
Are they of specific department stores?
I don't think so. I believe at least some, if not most, of their stock is direct from manufacturers.
It was on this day in 1927 that a man named Philo T. Farnsworth transmitted the first ever all-electronic television picture in history. Farnsworth had gotten the idea for television when he was just 14 years old, living on a potato farm in Idaho. His high school science teacher had gotten him interested in electricity, and he studied electrical engineering in his spare time. One day, he was tilling a potato field, walking with the horse back and forth, when he suddenly had a vision of a machine that could break an image down, line by line, and then reconstruct it on a screen.
And then his brother-in-law, Cliff Gardner, learned to make glass tubes.

Would it be weird to close my office door so I could chair-dance to Rage Against the Machine?
Going home on the El last night, I was angry and listening to Helmet. Nobody sat next to me. I think they could sense the homicidal fury. This morning I had Sleater-Kinney cranked to drown out the screaming baby.
I wish I had an office door I could close.
