got it! it is in Rialto at a corner of a shop (it should sell leather accessories such as purses, belts and bags). It is at the entrance of "Mercerie" the street (calle) that leads you to from Rialto to Saint Mark's. In particular it is in Campo San Salvador where a pillar stands (in memory of a historic event occurred when Venetians were under the Austrians -between 1814 and 1866).
1. The wavelength of the blue light given off by a mercury vapor street lamp is 436 nm.?
E = h c / wavelength h is Planck's consistent, c is the speed of light in m/s and wavelength could be expressed in meters The E that you calculate is in accordance to photon. So multiply the ensuing volume by technique of Avogadro's volume, and also you are performed
2. would You rather be a Street-LAMP or a LAMP-Shade?
I would rather be a Lamp Shade, because I would be much safer, than in a Street Lamp
3. would You rather be a Street-LAMP or a LAMP-Shade?
A street lamp. It's more use in times of need - and it sees more of life
4. How much electricity does a street lamp use?
This varies greatly. A commonly used lamp is low pressure sodium (the very yellow ones). This would likely be 90w (but there are bigger and smaller) so 0.09 X 24 = about 2 kWH per day. The brighter yellow ones are high pressure sodium and would likely be about 150w (again there are bigger so maybe 250w or 400w). The newer white ones are metal halide and probably about the same power as a high pressure sodium with better light. You may find the odd mercury vapor light (white) in older fittings. So, no real answer unless you know the type of fitting.
5. What does it mean when a street lamp goes off upon reaching it?
ah faulty wiring??
6. would You rather be a Street-LAMP or a LAMP-Shade?
neither...I AM a disco strobe light! Ill make you all epileptic =)
7. A street lamp weighs 150 N it's supported by two wired that form an angle of 110 with each other?
the vertical component of the tension in each wire supports half of the weight of the streetlamp the wires each form a 55 angle with the vertical (110 / 2) t cos(55) = 150N / 2 for an 80 included angle ___ t cos(40) = 75N
8. Is a landlord required to have a street lamp on a street when they rent every house on the street?
The only time I've ever seen privately maintained street lights is out in the country
9. A tree is planted 30ft from the base of a street lamp that is 25ft tall.?
height of lamp post = 25 ft, height of tree = H, length of shadow = L using similarity of triangles 25/H = (30L)/L 25*L= 30*H H*L i.e (25-H)*L = 30*H L = 30*H/(25-H)
10. How does a sensor in a Street lamp work?
Light shines on an electrical component called a "photoresistor",the characteristics of it change with the intensity of the light.When the value of it reaches a predetermined point,a simple electronic circuit turns the street light on or off as needed
11. What color of light does a low-pressure sodium street lamp give off?
When it warms up it gives off a yellowish orange light. Not very good for colour rendition but does show up details very clearly as this lift is very close to the most sensitive eye response. The picture is One I rescued one from outside our house when we were changed to LED. What color of light does a low-pressure sodium street lamp give off?
12. A street lamp weighs 150 N. It is supported by two wires that form an angle of 150° with each other. The tensi?
street lamp weighs 150 supported wires form angle 150 tensi
13. A street lamp weighs 190 N. It is supported by two wires that form an angle of 140° with each other?
Answer to (a) is 142.11N approximately. You have to resolve the forces. It is assume that the lamp is in equilibrium For (b) it is 4067.474N It is actually = Half the weight upon cos of half the angle.
