In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.[1] It occurs because lenses have different refractive indices for different wavelengths of light. The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each.
Answer:Increase in the entropy of the universe are the result of chemical reactions
Explanation:
The second law tells about the quality of energy such that any isolated system tends to become more disordered. Any natural Process occurring on its own is irreversible and entropy is increasing for that process.
The entropy of the Universe is increasing which is the result of chemical reactions. Any chemical reaction which increases the number of gas molecules will generate more entropy. Entropy in simple meaning is the order of randomness.
Answer:
The elastic potential energy PE=143.47kJ
Explanation:
This problem bothers on the potential energy stored in a material.
Given data
Mass of the bungee jumper
m= 75kg
Height of jump down the cliff h=195m
We know that the elastic potential energy stored is same as the potential energy of the bungee jumper
PE= 1/2kx²= mgh
Assuming g is 9.81m/s²
PE= 75*9.81*195
PE= 143471.25J
PE=143.47kJ
What is potential energy?
Potential energy is the energy possessed by a body by virtue of it position.
