OK - I am not a nut case nor do I dabble in UFO-mania. However, I sometimes see an object in the sky which I would describe as looking similar to a police car's flashing lights - only from, say, a mile or two away. Or it looks a bit like an airplane nearing an airport for landing - only it just floats there. There are 3 or 4 colors: Mostly green, then red and white, occasionally blue. They randomly flash in no partiular order, but fast. It sometimes appears to hover back and forth or even bob slightly up and down. I live just North of San Francisco, in Marin County. This thing is not always there but when it is it's almost always low in the Eastern sky. I won't go into the STUPID stuff some of my friends surmise about this thing. Suffice it to say that I question the police's need to spy on my friends (all of whom work part-time fast food jobs, live at home with their folks and still hangout with our highschool pals). Does anyone (who is educated/rational) know what I am seeing? Thanks

do you think there are planets like Earth that have human-like animals.....or whether there are other planets which are as advanced as we are?

for example, when looking across a long distance you see those "heat waves" (dont know what thier called)

and also when there are clouds can satellites view the ground (prob not, but who knows)?

Ok, I have a sub prime lender because I dont have he greatest credit. I think Im paying more than I was told for interest though, unless im figuring it wrong which is why I can use the help of anyone better at math than I am.
The cash price of my car is $19,990.00
Document Fee +$198.00
Lien + $1.00
Subtotal $21189.00
Sales tax financed + $1001.28
Total Sale Price + $21190.28
Trade In -$3500.00
Cash Down -$1000.00
Balance Due $16,690.28
Monthly Payment is $426.36
for 60 months = $25581.60
(it could be 61 months) which would add up to be
$26007.96

How is it that an entire room can be illuminated by one small light source, yet when that source is stopped, every trace of light is gone?

Is it just instantly absorbed by the surrounding surfaces?

I would think there might be a brief moment where the residual light is reflected back and forth between the walls or something.

Would the effect be the same in a room with a completely reflective floor, ceiling, and walls? Or would the light energy bounce continuously off the walls, keeping the room illuminated even in the absence of continuous source of light?

I'm sure there is a simple explanation, but please, enlighten me.

if you boil down 3% h2o2 (hyrogen peroxide) down to 1/10 of the amount you can get a 30% consentration.

How much must be boiled out if i have 6% Hydrogen peroxide

Suppose that the coefficient of friction between your feet and the floor, while wearing socks, is 0.250. Knowing this, you decide to get a running start and then slide across the floor.
Part A
If your speed is 3.00 when you start to slide, what distance will you slide before stopping?
Express your answer in meters.
1.84
Correct



Part B
Now, suppose that your young cousin sees you sliding and takes off her shoes so that she can slide as well (assume her socks have the same coefficient of friction as yours). Instead of getting a running start, she asks you to give her a push. So, you push her with a force of 125 over a distance of 1.00 . If her mass is 20.0 , what distance does she slide (i.e., how far does she move after the push ends)? Remember that the friction force is acting anytime that she is moving.
Express your answer in meters.
