I was wondering....
Say some people are talking quietly in a room with the door open. And there are some more people in the hallway and around a corner that can hear them. If the people in the hallway talked, would the people in the room be able to hear them as clearly as the people in the hallway heard them?

We can't predict or see an asteroid or comet crashing into the Earth until it hits us, let alone stop it, or so I've read. And I don't see space exploration benefiting us in any ways, except for statelites and the tempur-pedic mattress. Shouldn't that time and money be spent on something closer to home?

Just want to know if you get to know the answerers/questioners for what they contribute on Yahoo Answers. I am not asking whether you get to know them personally. For example, apparently in the category Yahoo products/ Yahoo answers they seems to know each other. However, this is not the case in the category Movies.

Can anyone tell me the relationship between the number of speakers (or other sources of sound) and the sound level.

For example, if you had a speaker playing at max volume and recorded the volume at 70db, then played another identical speaker next to it at max volume. What would the increase in total decibels be?

(Sorry i'm not sure how to explain this question properly, but i basically want to relate it to people in the audience at a rock concert - basically to define how 60,000 people shouting at the same level sounds just a bit louder than 1 or 2 people shouting!!).

Can a laser light burn away small dust and even insect away?
In ordinary home?
Without burning human like puting it in front of the window and door and ventilation from the outside exit?
Or just to scare insect away by use of disco light or simply use light first and the laser will be activated everytime some insect passes by and burn the insect ?
Just a theory?

Why does it take longer to open-and-close one eye (wink) then two eyes (blink)?

You would think it would take less time to just close one.

At one minute to midnight, a mathematician placed ten balls, numbered one through ten, into a vase and removed the ball marked with the number one.
* At one-half of a minute to midnight, the mathematician placed ten more balls, numbered eleven through twenty, into the vase and removed number two.
* At one-third of a minute to midnight, the mathematician placed ten more balls, numbered twenty-one through thirty, into the vase and removed number three.
* At one-fourth of a minute to midnight,...

At midnight, how many balls are in the vase?

My friend tell me that the answer is "zero". Can you explain ...

His argument is
"Name any ball and I will tell you it is not in the vase. Not only that, but I will tell you the exact moment at which it was removed from the vase "

An estimate with an explanation would be ok. Try to solve it without looking up anything.
