Neutrinos and photos are both created by fusion and both leave the Sun. The neutrinos reach the Sun's surface after about 3 seconds and the photons can take 100,000 years to reach the surface, which is why I said studying the neutrinos from the Sun tells us about fusion happening right now. Why do the particles take different times to cross the same distances?

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.
