Which of the foilowing statements are correct? Select one or more: D a. The axis on which we usually plot the dependent 1' independent variable is determined by convention. However, this convention may be overridden by other graphing conventions. C] b. By convention, the dependent variable is usually plotted on the vertical axis. III c. By convention. the dependent variable is usually plotted on the horizontal axis. C] d. The variable which we choose / control the values of, is usually plotted on the vertical axis. D e. Historicaily, the vertical axis was sometimes known as the abscissa. E! f. The dependent variable must always be plotted on the horizontal axis. The ideal gas law is: PV= nRT where P = pressure of the gas. V: volume ofthe gas, T: the temperature ofthe gas, and you can consider n and Ras constants. For a container of constant volume, you vary the pressure and measure the resultant temperature. You then plot temperature vs pressure (with temperature on the vertical axis and pressure on the horizontal axis). From the ideal gas law. you would expect a straight line. What would you expect to be the gradient of that straight line? Select one: 0 a. 1'1er V O b. 1/ V O c. :1]? 0 d. W of? O a. 3 1 M? O f. v You measure the distance a ball rolls down a long slope. starting from rest, overtimes of \"I, 2. 3, 4, 5 and 6 5. You plot a graph of the distance the ball rolled down the slope in the given time vs the time taken for the ball to roll down the slope. What is your "dependent" variable? Select one: C) a. the value of the gravitational acceleration g C) b. the time taken forthe ball to roll down the slope O c. the speed of the ball at various points during each descent 0 d. the gradient of the slope 0 e. the distance the ball rolls down the slope in the given time
