I feel bad. I read that flies can give you all sorts of nasty diseases. It was immobilized in the sink and I gave it to the spider that lives near some plants and it started to eat it. I heard the fly buzzing trying to get out :(. What have i done? Was it wrong to impede on nature?

I do not mean the meteors either. There where two silent lights as bright as a planet crossing the sky and then faded in a clear cloudless night?

Given 2 cylinders with :
ratio of the
circumference - 3/4
Lateral Face - 9/16
the diameter of the base - 3/4
volume - 27/64

a. If the Surface Area of the small cylinder is 243cm^3, what's the Surface Area of the larger cylinder?

b. If the volume of the larger is 144cm^3, wat's the volume of the smaller cylinder?

I can't seem to solve this so pls help me by giving me ur solution. that can rili help me a lot. Thank you guys!

i go out side to side the show and I ONLY see trees, as I asked earlier do you think I should take out my chainsaw and cut these babys down, as they are blocking my view, and I dont want to leave my yard, as the secret service are following me and I know they are trying to nap in my bushes, thought he chainsaw may make them wake, I just dont know what to do? its now 3:11 am time is of the essence!

(iz3,0)^401.

find all the roots of the equation z^3 + 1=0. give your answer in exponential and algebraic form.

To all the disappointed watchers:
So you stepped out onto the back porch last night and did not see much at all?
Try again, the showers will go on for a couple more nights.
But let's get real.
The best time to view the showers is around 3-4 AM. this is when perseus is high in the sky. The reason you can't see them earlier is because when close to the horizon, the show gets lost in the atmospheric haze and all the light pollution from surrounding cities.
Also, dark adaptation of your eyes takes over half an hour, until then you are not going to see anything, no matter how dark it is outside.
So, if you looked outside for 15 minutes and gave up. no wonder you didn't see anything.
The predicted count at maximum actvity is 60 per hour. But you are not always facing in the right direction to see all of them.
Like anything else, but even more so in Astronomy, it helps to do your homework, so you know what to expect.

If i know the temperature of a mass of black coffee (say 0.4kg at 350K) and I know the mass and temperature of some milk (say 0.1kg at 280K) and i assume that both of these have the same specific heat capacity, how do i go about determining the final temperature of the coffee when the milk is added?

I'm just looking for the relevant equations to use really rather than being given the answer

Is it just the hazy sky where I am (Wisconsin), or is this shower shaping up to be...well, less than a shower? If we were talking weather I don't think I would have needed an umbrella. I was out for about half an hour, 3am to 3:30am Central time, and I don't think I saw ten Perseids. Heck, I think I only saw about 3 Perseids for every random meteor (3 or so of those). I'd heard estimates of 1-2 meteors per minute. Anybody else see a better show than I did?

I really don't get it...why do empirical formula have ratios and how do molecular formula involved in empirical formula...I read some sites..but I can't understamd it,,

anybody who's willing to explain it...you can show some problems..if you want..

well, thanks in advance...

Alright, so I was watching the meteor shower all night and I saw a good amount of normal meteors, the ones that just look like shooting stars. Although, there were 3 different times when I saw something that I have never seen before. I KNOW that my mind wasn't playing tricks on me. It looked like a flock of geese flying -almost floating- in the shape of a V like geese usually fly. I followed these floating "geese" a lot farther than the normal meteors, and also, they seemed closer. Does anybody have an explanation for what I saw, besides 1) They were geese, or 2) I'm nuts...?

I read somewhere that the sense of smell, being most related to our brain stem, wherever that is, presumably the lowest point, where the 'stem' usually is, leaving the roots to their own devices, is the last to fail us when we take our leave of this mortal coil. Is that true?
