If you do not have the capacity to monitor their exercise behavior directly, you can operationalize “amount of physical activity” as the amount indicated on a self-reported questionnaire or recorded in a diary. Because many of the qualities studied in the social sciences are abstract, ...
Sometimes you might want two plots in a single graph even though the plots display completely different physical quantities. After acquiring and charting in a single graph the temperatures for the engine cylinders, you might want to measure the pressure in the cylinders and create a graph that pl...
In Fig. 5.16a, the lengths of the x- and y-axes do not conform to the scaling (-1 to 5) and (-1 to 2). In Fig. 5.16b, the lengths of the axes have been adjusted to the scaling. 27. As we have defined these quantities as accelerations, their unit is N/kg. 28. Open to...
