An led lightbulb has an efficiency of 11,5% and a power of 10 w. how much
light energy does the lightbulb produce in 1 second?
o a. 1.153
ob. 8.85 j
o c. 103
o d. 3,25 j

The light bulb produces 1.15 J  energy in 1 second.

Explanation:

Efficiency of an electric appliance is defined as the ratio of output power to the input power. In a 100% efficient appliance all of the input power will be converted to output power. In the given question  it is given that

input power= 10W  

efficiency= 11.5%

(output power)/(input power)=efficiency  

output power = input power * efficiency

Now we have to calculate the energy produced by the light bulb in 1 second

=1.15J

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
