For the situation in part f, find the magnitude of the force f (in kg⋅m/s2) necessary to make the block move. View available hint(s) hint 1. Numerical solution opened hint you solved for an expression for f in the last part. What numbers must be plugged in to solve for a numerical answer?

What occurs during a combustion reaction

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.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
