A Street Light Is Mounted at the Top of a 15-ft-tall Pole. a Man 6 Ft Tall Walks Away ...?

we will have 2 triangles: the big triangle, top of light pole "A" , base "B" and the tip of the shadow "T" and the small one, the height of the runner with head at A', feet at B' and T the tip of the shadow the triangles are proportional, 6/15 = (AT - 45) / A T AT = 75 ft S = v* t the guy spared t = S/v = 45/7 = 6.43 seconds same time spend by the tip of the shadow, but the space (") is bigger 75 = v * t = v*6.43 ===> v = 75/6.43 = 11.66 ft/s

3. I have a street light that needs a power source. I'd like to use solar instead of hard wire. What system should I use?

Q: I have a street light that needs a power source. I would like to use solar instead of hard wire. What system should I use? A: One that can accumulate and store in a battery on the shortest darkest day of the year enough energy to illuminate the entire night which is going to be the longest night of the year.

4. A woman of height of 6 ft walks at a rate of 7ft/s towards a point P directly beneath a street light that is 30 ft above the ground .What is the rate of change of the distance between the tip of her shadow and the point P?

Let the length of the woman's shadow = xand let her distance from the street light = yThen by similar triangles, we have6/x = 30/(x y)6(x y) = 30xx y = 5xy = 4xThe tip of the shadow is always (x y)/y = 5/4 times as far as the woman from the point P, so it must be moving at 5/4 times her speed.Thus the rate of change of distance of the tip of her shadow from the point P (or its speed) is7 ft/s * (5/4) = 8 3/4 ft/s.A woman of height of 6 ft walks at a rate of 7ft/s towards a point P directly beneath a street light that is 30 ft above the ground . What is the rate of change of the distance between the tip of her shadow and the point P?

5. A 6 foot man walks at 8 ft per second toward a street light that is 20 ft abovethe ground (cont.)?

nicely in case you draw this out, you will desire to be conscious that they are comparable triangles. One is 6ft (top) and 20ft(length 50-30=20) it extremely is the triangle from the sunshine source to the guy. permit x continually be the present top of the shadow. the 2d triangle is the somewhat construction to the sunshine source. This triangle is x ft severe it extremely is somewhat the top of the shadow, and 50ft long. The triangles are comparable by way of having 3 comparable angles(I talked approximately because it AAA similarity) remedy for x 6/20 = x/50 20x = 3 hundred x = 15ft So at first, the shadow is 15ft tall on the construction. next, I permit the guy flow 5ft in direction of the construction. So your first triangle is now 6ft for top of and 25ft for length the 2d triangle is x for top of the shadow and 25ft for length remedy for x returned 6/25 = x/50 25x = 3 hundred x = 12ft So the shadow is now 12ft tall. finding at the two heights, the shadow is shrinking at a value of 3m/s I even have faith that this shrinking is linear. verify to work out if its linear bypass yet another 5ft First triangle 6ft and 30ft 2d triangle x and 50ft 6/30 = x/50 5x = 50 x = 10ft Dam lol so the equation is not linear. So i am getting a table of values now. 6/35 = x/50 35x = 3 hundred x = approximately 8. 6 it extremely is it for me immediately. i am going to calculate the deceleration of the shadow after a good nights sleep

Smart Street Light Establishment JC Global Foundation
Scheme to set up solar street lights is being implemented across the country to facilitate solar street lights in in general villages. Recent technical advancements have paved the path to the rebirth of solar street lights. As this is one of the best energy efficient solutions. In a tropical country like India, adoption of solar street lights can make more practical sense while empowering the energy management system of the country. Currently, the solar street lights are established in rural areas as they are more useful in villages and provide lighting in streets. There is an inevitable need of electricity in rural areas, mainly for night lighting and tis problem can be easily solved through solar light establishment. Keeping in mind the electricity needs of such households living in rural areas, solar street establishment are made available in rural areas. We, at JC Global Foundation, aim to bring energy management solutions across the world through solar street light establishment at public places. With the solar street lights establishment, we intend to empower the adoption of solar based energy efficient systems along with the cutting-edge solar lighting technologies. It is necessary to create public awareness regarding renewable energy in order to establish solar street lights on a large scale.1. Is this a good tank set up?Too many fish... I think the max rule is 1 fish per gallon of water. You will need more algae eaters too. What kind of lighting are you using?2. question fo professional photographers Canon lens?If you've been using your XT for a while, you should have a good idea of what focal length works best for you. My guess is something like 50mm. If you want better image quality in that range, you coud pick up a Canon 50mm f/1.8. These are fairly inexpensive and you can use a larger aperture than with any zoom lens. But a zoom lens - even the 18-55mm kit lens - should work nicely until you have specific reasons to upgrade. Also pay attention to how other portrait photographers use lighting. This is at least as important as buyng a better lens.3. how to get the best video quality out of canon dlsr?It's not a question of "the best setting." It's a question of understanding exposure, lighting, dynamic range, lens quality, which aperture to use, etc. etc. etc. In other words, go learn the basics of photography and the basics of cinemaphotography -- then your video will improve. The camera is quite capable of stunning video, but you need to know how to get it. Peace.4. Can seeds from store bought ORGANIC fruits and vegetables be planted to grow your own vegetables or fruits?As others have said, just avoid the hybrids. They do not usually have much flavor. You want to look for "heirloom" seeds. These are the ones that usually have not been altered in some way. Some of my favorites are not heirlooms at all, but if you are inexperienced, that's always a safe route. I get my seeds from locals I trust, from my own plants that I've harvested, from nurseries, even sometimes from Home Depot, because I've come across some great ones in hardware stores (not always, but consistently). You can even try places like ebay, at least as long as you trust the source. (After all, anyone can claim they are growing organic/heirloom/whatever seeds.) If you are going to grow indoors, though, you need to consider germination temperatures and lighting. Some peppers require higher temperatures to germinate. Other seeds need to be frozen or refrigerated first. You also need to consider your climate and whether or not you will be moving the plants outside. If you are going to do this often, I have some suggestions for indoor lights. Feel free to email me if you need help with anything. I've been starting my plants indoors in many different climates for years.5. Do you look different (bad lol) in certain lighting, like fluorescent? BDD?When a person has BDD, things like lighting can make them see a completely different person in the mirror. The truth is, you looked exactly the same without the lamp as you look with the lamp. Some types of lighting can flatter certain people, or make them look worse, but the difference is not too dramatic. If I were you, I would put a dimmer lightbulb in your lamp or get rid of it. Even though others are not seeing what you are seeing, you should avoid things that cause issues with your BDD
