The graph below shows the blackbody radiation curves for four stars. The image shows four blackbody curves, plotting the wavelength and relative brightness of stars at various temperatures. The x-axis represents the wavelength in nanometers and the y-axis represents relative brightness. There is a band of color represented as part of the graph vertically, purple, blue, light blue, green, yellow, orange and red from left to right. Curve 1 peaks at a wavelength of 600nm, Curve 2 peaks at a wavelength of ~480 nm, Curve 3 peaks at a wavelength of 500 nm and Curve 4 peaks at a wavelength of 350nm.

Which of these conclusions is correct about the curves?

When temperature increases, Curve 3 moves towards Curve 4.
When temperature increases, Curve 3 moves towards Curve 1.
When temperature decreases, Curve 2 moves towards Curve 4.
When temperature decreases, Curve 2 moves towards Curve 3.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
