Assume it takes 7.00 minutes to fill a 30.0 gal gas tank. (a) calculate the rate at which the tank is filled in gallons per second. (b) determine the rate at which the tank is filled in cubic meters per second. (c) determine the time interval, in hours, required to fill a 1.00 m^3 volume at the same rate. ( 1 us gal = 231 in.^3)

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e

What is the length x of the side of the triangle below? (hint: use the cosine function)

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.
