4. A truck with a mass of 6,500 Kg can exert a force of 29,250 N when stopping. What is the deceleration rate of the truck?

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.

How does changing the frequency affect the energy of the wave?

Why are nonmetals more likely to react with eachother by sharing electrons
