Vector A with rightwards arrow on top = -1.00i + (-2.00)j and vector B with rightwards arrow on top = 3.00i+ 4.00j. What are the magnitude and direction of vector C with rightwards arrow on top = 3.00A with rightwards arrow on top + 2.00B with rightwards arrow on top?

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.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

A6.0-kilogram cart initially traveling at 4.0 meters per second east accelerates uniformly at 0.50 meter per second squared east for 3.0 seconds. what is the speed of the cart at the end of this 3.0 second interval? (1) 1.5 m/s (3) 3.0 m/s (2) 5.5 m/s (4) 7.0 m/s
