Cognitive psychology PSYC2300 at the University of Newcastle. Design and stimuli The 3 x2 within participant design experiment consisted of two phases. The first phase was a study phase (60 trials) in which participants were asked to process words (5-7 letters in length) to different depths by answering (yes/ no) to various questions about the words (typeface (upper/lower)‚ phonemics and meaning)‚ all presented for 200ms. The second phase was a surprised memory phase (120 trials) that measured

description and explanation. Say V = 5V‚ R= 1 Ω and L = 1H. Assume inductor is initially uncharged. FIGURE 1 From Figure 1: At t0‚ switch is opened. VL= L (di/dt) . L = 1H di=(Ifinal – Iinitial) = (0 – 5) dt= 0.02s‚ say it takes this amount of time to open the switch. Hence‚ VL = (1) (-5) (0.02) VL = -250 V The electrical potential difference is so great that the air between the contacts of the switch might ionise to provide a conductive path for the current. Consequently

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

A vigorous stream of air is being drawn through the solution for about 1-2 hours 4. 35ml of concentrated hydrochloric acid is added 5. The solution is then being evaporated on a steam bath until a crust forms over the surface. 6.

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

it‚ considering the other forces of known magnitudes. Thus‚ if weight is one of the forces‚ we could really get the mass of that specific object. In the first part of the experiment‚ the first mass pan has 10 g weights on it while for the second‚ 5 g. By balancing‚ we measured a distance of 10 cm and 14 cm for each corresponding weight pans‚ P1 and P2. The weights added to pan 1 and pan2 affect the positions in the model balance if one contained a bigger mass compare to the other. Because they
