Street Light Cut Off When I Go near Them?

Only use your powers for good, with great power comes great responsibility

1. what does it mean when i drive under a street light and it turns off?

"Oh sht, he gonna hit into another pole again turn the light off"

2. how many full days of sunlight would it take to power one solar powered street light?

It depends on the rainy days in your place, the battery will design by this and supply the full power to the solar street light when night using

3. How do i get a Street Light installed at my home?

if that does not work, hit somebody with your car and sue the city because of poor lighting and visibility. That will get one up real quick

4. What are the cameras on top of a street light at a intersection?

Those are traffic cameras. They observe if the traffic is packed or clear

5. A street light is at the top of a 17 ft pole... (calc rate problem)?

her length is 4ft = Yp the street light length is 17 ft = Y the length of the shadow is Xs & Xs' is the rate of the length of the shadow the distance from person to light street is Xp = 29 ft & X'p = 4 ft/s the total horizontal distance = the distance from lamppost to person the length of the shadow X = Xp Xs now it will be solved as the following ratio : [ Yp / Y ] = [ Xs / X ] [ 4 / 17 ] = [ Xs / ( Xp Xs ) ] ======> cross multiply [ 4 / 17 ] * ( Xp Xs ) = [ Xs ] (4/17) Xp (4/17)Xs = Xs (4/17) Xp = Xs - (4/17)Xs (4/17) Xp = (13/17)Xs 4 Xp = 13Xs (4/13) Xp = Xs using the equation====> X = Xp Xs X = Xp (4/13) Xp X = (17/13)Xp =====> differentiating X ' = (17/13) (Xp)' X' = (17/13) * (4) = (68/13) ft/s X = Xp Xs ======> differentiating X ' = Xp ' Xs ' (68/13) = 4 Xs ' (68/13) - 4 = Xs ' Xs ' = 16/13 = 1.23 ft/s ========= please e-mail me if u have a question

6. can plants release oxygen by photosynthesis with street light at night?

Nope. Street lights are too weak in intensity ehich is insufficient for most of the plants. Besides many plants are wavelength sensitive i.e. they photosynthesize under a particular range of wavelength( normally the yellow range) wavelengths longer than 700 nm appear to be unable to drive photosynthesis. The wavelength is too long, the energy content of the photons too low. The street light has to be of that wavelength and of sufficient intensity for the plants to photosynthesize!

7. I hate street light cameras?

it wasnt a camera bro. it was a ufo

8. a street light is 15 ft .... ?? 10points?

A Street light is 15ft directly above the curb. A man 6ft tall starts 10ft down street from the light and walks directly across the street which is 10ft wide. When he reaches the opposite curb, the distance between the initial and final positions of the tip of his shadows is given by 16 2/3 ft ANSWER From first shadow along side of street is (10 6*10/(15 -- 6) ) ft = 16 2/3 ft second shadow along diagonal at 45 degrees to first shadow is rt2 10rt2*6/ ft = (16 2/3)rt2 ft

9. How does the stop and go street light know when a car is waiting?

Sensors in the pavement called "loop detectors". You can see them if you are at the intersection. They look like rectangular cuts in the pavement. Usually these work in conjunction with a timer depending on the time of day

10. Do you think your city would welcome a more efficient street light system like Los Angeles will have?

I am sure Baltimore would welcome any improvements that might help reduce violent crime assuming the cost was reasonable

11. When you were a kid did you often break the street light rule?

My Dad was a Sergeant in the Army during WW 2. Have you ever heard one of those guys yell? We made it home as soon as the lights came on. Having the entire town know you were late just was not a pleasant event.. we would hear all about it at school the following day.. Sigh.
