The acceleration due to gravity on the moon is gm. Suppose an astronaut on the moon drops an object from a height of h. The time it would take the object to reach the moon’s surface would be tm. The same object is dropped from the same height on earth, where the acceleration due to gravity is ge. The time it takes the object to reach earth’s surface is Te. Required:
What is a correct mathematical relationship for the two times?.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
