Knowing that slider block A starts from rest and moves to the left with a constant acceleration of 1 ft/s2 , determine (a) the relative acceleration of block A with respect to block B, (b) the velocity of block B after 2 s

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

Apossible explanation for a set of facts that can be tested by further investigation is called

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.
