As shown in the figure below, Luis walks 40\,\text m40m40, start text, m, end text toward his truck. He notices he forgot his keys, so he returns back to his house. His total travel time is 95\,\text s95s95, start text, s, end text. The bottom of the diagram is green. To the left side is a blue house with a red roof. To the right side is a blue truck. Between the house and the truck is a black stick figure. A grey dashed arrow labeled "40 m" points rightward from the house to the truck. Another grey dashed arrow labeled "40 m" points leftward from the truck to the house. The bottom of the diagram is green. To the left side is a blue house with a red roof. To the right side is a blue truck. Between the house and the truck is a black stick figure. A grey dashed arrow labeled "40 m" points rightward from the house to the truck. Another grey dashed arrow labeled "40 m" points leftward from the truck to the house. What is Luis’s average velocity over the 95\,\text s95s95, start text, s, end text period? \dfrac{\text m}{\text s} s m start fraction, start text, m, end text, divided by, start text, s, end text, end fraction What is Luis’s average speed over the 95\,\text s95s95, start text, s, end text period? \dfrac{\text m}{\text s} s m start fraction, start text, m, end text, divided by, start text, s, end text, end fraction Answer using a coordinate system where rightward is positive. Round answer to two significant digits.

Need asap ! what is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere?
