...it (McNamara, 1991). The last action that was carried out was t compare the trials were gestalt was and was not presented. It should be noted that the whole process was computerized such that detection of any change could be tracked to detect the stimuli affected. The analysis of variance was then used to analyze the findings (Coren & Girgus 1980). Results The results were as shown below Based on the **2** X 5 Repeated measures ANOVA, it was found that the main effect of gestalt presence F (1, 32) = 15.637, p < .001. On the other hand, the main effect of stimuli change F (4,128) = 45.358, p < .001. By combining and **correlating** the two, it was found that the **significant** interaction between...

...electrode that is equal and opposite to the accumulated negative charge on the other. Thus the charge on the electrodes is equal to the integral of the current as well as proportional to the voltage, as discussed above. As with any antderivative, a constant of integration is added to represent the initial voltage V (t0) (Hammond). This is the integral form of the capacitor equation: Q= CV ………………………………………………………… 1 V (t) = Q (t) /C …………………………………………………… **2** Taking the derivative of this and multiplying by C yields the derivative form: I(t) = dQ(t)/dt = CdV(t)/dt ………………………………………………3 The experiment however has a number of sources of errors which actually hinders that achievement of the most accurate results. These errors and...

...Article Critique WHO RULES AMERICA By G. William Domhoff In the article, the has taken a commanding tone right from the start while describing how power is being controlled by the rich minority group in United States. According to the author, there are generally four categories of stakeholders in the US who have influence over the political decisions taken. One is the corporate community which comprises the large income producing property owners who control the national scenario. The growth coalition comprises the subcategories of corporations and they control the local government. The third category is defined in the 'pluralism' theory that the general public controls the government through the voting and electing of governmental...

This study will entail looking at the buying patterns of adults in the community. Random products will be selected to determine whether or not, specifically, advertising on television causes people to buy more of the product, or whether there are other factors that have more **significance** in determining which product adults buy. The necessary components, then, are a survey instrument, access to a selected panel of adults, and research about which products to include in the questionnaire.

**2**. Based on your scatterplot, what time range does calibration have a **significant** effect on age estimate? What might cause this effect?
Time range =between 5420 and 5410 years.
It is this time range because it gives an “age plateau” whereby a wide span of real time is covered. The **significant** effect occurs at this point because of the combination of large influx of 14C-depleted, carbon from the oceans, and decrease in the rate of 14C production from the atmosphere causes the “age plateau”

...Science Lab **2** Science Lab **2** Introduction Speciation is the natural change in a species’ behavior and prevalence over a given periodfollowing a natural disturbance. This disturbance often cause of the species to locate to a different natural setting forcibly and almost immediately. In effect, the species is compelled to adapt and change to fit these new natural surroundings. The following lab report methodically accounts for the series of events following the sudden split of a species of lizards into two groups by a hurricane resulting in the isolation of a small group of individuals on an island far from the mainland.
