EXAMPLE: A certain 100-watt bulb emits a total luminous flux of 1200 lm, distributed uniformly over a hemisphere. Find the illuminance and the luminous intensity at a distance of 1 m, and at 5 m.
SOLUTION: The area of a half-sphere of radius 1 m is
(2[pi])(1 m)² = 6.28 m²
The illuminance at 1 m is
E = 1200 lm ÷ 6.28 m² = 191 lm/m² = 191 lux
E = P.t
E = energy (joules)
p = power (watt)
t = time (seconds)
and watt means number of joules per second
therefore, energy = 100.1 = 100 j/s
"Electricity" is a word that can not be quantifed so you can't ask how much there is. But it is possible to measure electric current (amps), voltage (volts) and power (watts) and even also electrical energy (watt-seconds or kilowatt-hours). A hundred-watt bulb uses 100 watts of electric power and if shining for ten hours it uses 1 kilowatt-hour of energy.
Its equal to Fourquadrillion.True my friends!!!!!!!!!!!!!!
it depends what type genius, if it's a 100 watt bulb then its watt is 100.
It produces about 1200 lumens, about the same as a 20 watt CFL bulb.
It depends on how close you place them. right next to your eyeball and you'll need just one.
If they were all out at the suns distance, then it would be in the region of 3.8 x 1024
Wikipedia states the Sun's luminosity as 3.846×1026 watt.
There would not be any. The electrons and protons would be equal so there would not be any that are leftover to use.
1.5grams is equal to how many ml?
About 1013 millibars would equal about... 30 inches------------_______________*****************
There are 1000 milliliters in one liter, so 5-6 liters of blood would equal 5000-6000 milliliters of blood.
1 litre = 1000 ml (of any substance) 750 ml = 3/4 litre (three quarters of a litre)
how many led christmas lights to equal 4100lm

There are many functions for strip lights. One example is used for decorative purposes. These lights are normally low level bright lights. Another example is background lighting with high level brightness. As an example you may see these light in storefront windows for background lighting.
The word bright has one syllable. It is pronounced BRYT.
Many types of buildings would be likely to install high bay lights. Department stores with many floors will likely install high bay lights as well as apartment buildings.
There are many different advantages surrounding the use of solar post lights. The most noted benefit would be that one would have a lower electricity bill as the lights are 'fed' by the sun.
These letters form the word 'lights'. It would be in reference to the many coloured lights and Christmas lights displays one sees during this season.
form_title= Emergency Lights form_header= Ensure safety with emergency lights! Would you like an audio alarm set to coincide with the lights?* = () Yes () No () Not Sure Do you want a backup power source installed?* = () Yes () No () Not Sure Would you like motion sensor lights?* = () Yes () No () Not Sure How many lights do you need?* = {1,2,3,4,5,6,7,8,9,10, More than 10}
There are many reasons why a head light would stay on when car is off. These lights could be automatic.
16 ounces would equal 1 pint, so 24 ounces would equal 1.5 pints.
