Outdoor Solar Lights

Three Questions:
Describe the sizes, temperatures, and colors stars can be.
Describe how distances are measured between the Sun, stars and Earth.
Describe the source of light for the Moon, planets, and other bright objects in space.

That is a lot more information than can easily be typed in here.
Stars can be as small as half the mass of the sun up to about 150 times the mass of the sun, ranging in temperatures from 3000 K up to over 40,000 K.

Distances within the solar system are measured in AUs (the average distance of the Earth from the sun, around 150 million kilometers.

Distances between stars are measured in light years (about 9 trillion kilometers).
Distances within the galaxy and between nearby galaxies are often measured in parsecs (3.26 light years) or kiloparsecs (3260 light years).
Stars shine by light they produce in themselves. Astronomical objects that are not stars (planets, moons, asteroids, etc) shine by reflected sunlight.

You know, I’ll bet you could find all of this (and more) in your textbook or wikipedia.

we had to make a cell brochure. mine is for a spa. tell me what u think of mi analogies 4 each.

Plantasia
Where your beauty fantasies come true…

Product Factory (Smooth ER)
You can request a special tour through our beauty factory where you can watch how our all natural proteins, lipids, and beauty products are made. Some are shipped to our store some are put to use in the spa. Then purchase the products that you loved during our stay here, so can get Plantasia beauty all the time.

Plantasia at Home (Rough ER)
Plantasia at home is our in spa beauty store where you can purchase all the proteins, lipids and other beauty products used here at Plantasia. We guarantee you (or your money back) that these are the products used in all of our spa treatment here at Plantasia. If there is one protein, lipid, or other beauty product used here that you can’t buy that was used at Plantasia you will get 1 spa treatment free of charge.

Chloro-color Room (Chloroplasts)
One the most popular treatments here at Plantasia, our chloro-color room. This unique room features soft double outer membrane chairs where you can lay and soak up the rays’ sun for the perfect summer tan. This room also powers the electrical needs of Plantasia. On the ceiling of the chloro-color room are solar panels, which convert light energy into electricity, which powers Plantasia. Plantasia is good for you and the environment.

Restaurant de Beauté (Mitochondria)
Our complementary 5 star restaurant with your spa stay, Restaurant de Beauté is an all natural all healthy food buffet. The food is prepared by world-renowned chef, and health expert Sasha Aires. No two menus are ever the same, but every dish is low in fat and good for you. Cooking magazine rated our restaurant as “one of the 7 wonders of the cooking world”, so get healthy, get energy and enjoy the wonders of the world.

Reinvigorating Tub (Vacuoles)
Here at Plantasia the Reinvigorating Tub is one of our most popular treatments. The fluid in the tub is infused with nutrients that revitalize your skin. Water here presses up against your spin causing it to become rigid and stiff giving you better posture and balancing the tugor pressure in your body. People come out of this treatment looking and feeling better 100% of the time.

Goldie Wrap (Golgi Apparatus)
This signature wrap will leave you with healthy skin and will package up your loose microtubules. Get wrapped in a stacked of membrane-bound vesicles that will tighten up skin, pores and microtubules. After this refreshing wrap take a nice hot shower to get beautiful pores and a healthy glow.

Hydro Bath Wrap (Cell Membrane)
The Hydro Bath Wrap is the best of both worlds, a wrap and a bath in one amazing treatment. The wrap is a double layer of phosolipids where you will enclosed from the neck down. Then you will be put in a hot bath where you hydrophilic head will be relaxed in the water while the wrap filters out the unnecessary water that the hydrophobic wrap does not need.

Plantasia Carts (Cytoskeloton)
Something that no other spa in the country has is our Plantasia Carts. They are made of imported microtubules; the seats are lined with Italian microfilament all put together with Egyptian intermediate fibers. What is a more relaxing way to get from treatment to treatment then in one of our Plantasia Carts?

ty for answering my question b4. I like your cell analogy too. It is very original and i checked it over and everything makes sense ^^. I had too do a similar project like this but i based my analogy on a city.

Im trying to do a solar usb charger from garden lights (idea from video link below). I got solar panels hooked up to give me ~5v DC already tested with a multimeter. I cut a male usb and turned it into a female usb port to hook up my phone, media player, ect. Then I hooked up the negative and positive cables to the red and black cables from the usb But its not charging any device.

1. Which color cables from the usb cable should i hook up to my negative and my positive from my solar array and do i need the white and green cables for anything?

2. If I need anything can you give me a link to how it looks like? I have a lot of electronic stuff but im new with hardware tinkering so i might have it laying around but might not recognize it

http://www.metacafe.com/watch/800000/solar_powered_usb_charger_cheap_and_easy_to_make

I tried diode, incandescent, and even the real sun. All 3 gave me good output of ~5V but i suspect its not that but something with amps?
So youre saying its not possible to get this to work?

There isn’t enough current really.

While the cell may be 5V, that is open. Put load on it and it will drop.

I have a 5" reflector telescope with a 5" cover that allows a smaller hole to be opened for reduced light transmission. It seemed to make the moon dimmer, but I also lost quite a bit of contrast (or resolution?) for some reason. I wonder if that little opening in the telescope cover has any purpose in protecting the internal optics during solar viewing, but all the solar filters seem to be aimed at covering the aperture, 5" in my case (and they are expensive, too). Anyhow, the moon filter seems like it would do the very same thing as making the aperture smaller, but people sell 1.25" moon filters, and 5" moon filters with neutral density and with other colors bias, like green. Do I need a neutral density filter, or some other kind, or does my aperture limiting with the hole in the cover already allow good moon viewing?
Is there any advantage for a 5" aperture ND moon filter over a 1.25" eyepiece ND moon filter?

Reducing the aperture is the same as using a smaller telescope, thus the reduced resolution. But I cannot imagine a real need for a lunar filter. It is not that bright, so unless you are concerned about reduced dark adaptation after lunar viewing, why bother. As for solar filters, a lot of the stuff that is provided with a telescope, especially the smaller and less expensive ones, is pure junk. Go with a good 5.0 neutral density filter. If you really feel the Moon is too bright, a 1.0 ND should be enough. Remember, at Full Moon you can’t see much in the way of craters or mountains anyway from lack of shadows.

In 1970 or ’71, while living in my native country in Caribbean, my mom, two neighbor children and myself, saw to the west in the sky what appeared to be a light green cloud, which suddenly started to spin wildly as it turned to other light tone colors, such as pink, peach, etc. Immediatedly we cross street over to our house which was across from park where we’d been sitting after dinner. No sooner we had crossed, that night began to fall very fast. By then most of neighborhood was outside our house, on the street, and on a smaller park on the right side of our house. My brother does not remember anything about it, even though he was there all the time and must have been at least 6 years old. One of the other boys was crying and shaking, as well as was my grandma! By now the thing had turned to huge blue circle covering most of the sky. Then slowly began to disappear until it was only a large spot which must have remained long after we’d gone to bed. Government gave various explanation

no, more than likely it was a rare occurence of the solar particles sticking earths atmosphere causing the lights. It’s pretty much like the northern lights, only it happened near the equator, very rare, but not unheard of. Either that or some sort of emp or ufo…but most likely just a natural phenomenon

(1) This contrast in color was suggestive of a solar eclipse.

(2) Together, his head and hair looked like a solar eclipse.

(3) The contrast between dark and light created the appearance of a solar eclipse.

So, what do you think? Are these sentences interchangeable? Below you will find the passge from which they have been extracted. Thank you for your suggestions.

Item 1 and item 3 are interchangeable, however the second item has an entirely different meaning. Honestly, if having to choose between 1 & 3, I wouldn’t be able to select either one as preferable to the other.
