6. You get to your dive site and park the car. You put on your gear and get ready to enter the water. But first you check your scuba tank. It is filled to a pressure of about 25,000 kPa at 300 K. The volume of the tank is 25 L. You begin to wonder: If pressure remains constant, what would happen to the volume of gas in the tank if its temperature increased? (6 points)
a. Which of the four thermal processes describes the temperature-volume relationship at constant pressure? (3 points)

b. Write the equation for this process. Hint: Think about the first law of thermodynamics. (3 points)

Waves that cause the most damage during an earthquake are a. surface waves c. s waves b. p waves d. ocean waves

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
