The wavelength of red light is 650nm (6.5 x 10-7m) and the wavelength of blue light is 500nm (5.0 x 10-7m). Find the frequency of blue light and red light.

The masses of the objects and their densities

The rocks expand when there hot/warm  and contract when they are cold.

Because its reliable.   there is no pollution  the chances of a radiation leak is low

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
