The zeroAength springgravity meter By LUCIEN LaCOSTE Austin‚ Texas took my only formal geophysics coursein 1932at the University of Texas. Arnold Romberg was the teacher. Early in the course‚he explained the .theory of the horizontal pendulum and showed that theoretically it has an infinite period when its axis of rotation is vertical. It behaves like a sphere on a perfectly horizontal table - i.e.‚ the sphere stays wherever it is put. Romberg also told us that no verticalseismographhad ever

The relationship between an object’s position and time if it travels in a straight line at a constant speed‚ as well as the relationship between the same object’s speed and time‚ will both result in a linear model. This hypothesis will be tested by using a model car‚ a spark timer‚ and timer tape. Procedure 1.Obtain a model car‚ spark timer‚ half a meter of timer tape. 2.Tape the length of timer tape to the back of the model car. 3.Feed the timer tape through the spark timer‚ setting the

The equation for the trend line is Y = 20.788 X - 0.0093 ; R ² = 0.9675. This equation will be used to calculate the unknown concentration of Methylene Blue solution. Figure 2: Standard curve of Average light absorbance by ten different concentration of Methlene Blue. The data is collected from all the groups in the class. All the points in the graph represent the means of all the groups. The figure shows a direct proportion. Its equation for trend line is Y = 23.569 X – 0.0043; R
