A student generates water waves in a pool of water. In order to increase the energy carried by the waves, the student should generate waves with a
(1) greater amplitude (2) higher frequency (3) greater wavelength (4) longer period

Why can blue light and yellow light combine to produce white light? question 17 options: they are both primary colors of light. they absorb each other's wavelengths. because blue, yellow, and white are primary colors. they are complementary colors of light.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

J. j. thomson’s experiment disproved the theory that an atom
