Astudent wonders if the bubbles on this water plant are often gas o2. however identifying a gas as o2 with direct evidence requires many kinds of equipment. which observation would provide indirect evidence that supports a hypothesis that the bubbles are o2. a. an increase in bubbles on the plant when it is moved under a brighter light b. a description of the shape of each leaf after a plant is kept under did light c. a decrease in approximate size of each leaf on plants kept in darkness d. a count of the bubbles produced over time by one plant under bright light

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
