60 watts = 60 joules per second
5,400 joules = (5,400 / 60) = 90 seconds, at the rate of 60 watts
But we must disagree with the language of the question.
At the rate of 60 watts, it takes 90 seconds to use 5,400 joules of energy. But no work is done.
The energy is converted into electromagnetic energy, in the form of heat and light, and it's
carried away from the light bulb by the E&M radiation.
The mood light will last as long as the bulbs life, which has a lifetime of an average household light bulb. once the bulb burns out, one must replace the bulb with another mood light bulb.
A Tube-light !
2000,00000,0000000 seconds or..... 15 hours
he improved the light bulb when he saw that it did not last long and broke easily
The long thin light bulb is called a fluorescent tube or a fluorescent light bulb. It is commonly used in commercial buildings, offices, and schools for general lighting purposes.
Thomas Edison had trialled many experiments his most famous one would be, where he created the first long lasting electric light bulb
Edison failed many times - no one knows how many - to make a filament for a light bulb that would last a long time. He did not invent the light bulb - he was working on a BETTER light bulb that would last longer.
Thomas Edison was the who pateneted the first light bulb
i think it takes about 10 seconds if you already have the light bulb in your hand.
1 nano secint
someone, but he IMPROVED the light bulb as well so... it wasnt the same for long
At the time of the light bulb's invention, the term of protection on a patent was 17 years.
