Jodied to run for exercise. To warm up, she walked at a constant speed for a distance of 100 min 100 s Then she increased her speed to 4 ms she ran at this speed for 5 min (300 s. At that point she began going up a steep it and her speed dropped back to 1 m/s. It took her 4 min (240 s) to reach the top of the him. At that time she stopped and rested for 3 min before continuing her run Construct a distance-time graph and a speed time graph of Jodi's motion Label the axes Then explain what is being shown as the slope of each Distance-Time Graph Speed-Time Graph

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
