constant. If a ball is attached to the end of string and swung at a constant speed (i.e. only the direction of the velocity is changing not the magnitude) then there must still be an acceleration. The acceleration is directed towards the center of the motion. This acceleration is call centripetal acceleration! 2.6.2 State the expression for centripetal acceleration. The acceleration of any object moving in a circle at a constant speed is given by the equation: (1) a⃗ =v2r It is important to note

ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model

loss from the hot water from combining it with the cold water. As discussed in a page titled Heat Capacity2‚ the heat capacity is defined as the amount of heat it takes to raise the temperature of a substance by one degree (in this case C). In the experiment performed in lab‚ the heat capacity of the calorimeters was calculated by subtracting the heat gain from the heat loss and then dividing that by the difference in the temperatures between cold water and the combination of the hot and cold water

How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°‚ 30 rad‚ and 30 rev‚ respectively? 2.1m‚ 1.2x102 m‚ 7.7. x102m 2.

The main focus of this experiment was to find the relationship between temperature and the enzyme activity of amylase. This was achieved by attaining amylase enzyme‚ starch solution and potassium iodide (determines if enzymes hydrolyses the starch solution)‚ water bath and a hot plate. The temperatures used for this experiment were room temperature‚ 37oC‚ 60oC‚ 80oC‚ and 90oC. The hypothesis developed was that as the temperature increased‚ so will enzyme activity. Therefore‚ the ability of the

The Afterlife Investigations: The Scole Experiment “Best evidence of life after death ever.” This is what this documentary film is pointing out. Is there really a life after death? Well this film makes me believe more that there is indeed a life after death. However‚ how can scientific evidence explain life after death? Now this film showed me how. The ninety-minute documentary film is about the Scole Experiment‚ which is a five-year investigation into life after death. It is conducted by

Individuals may change their behavior due to the attention they are receiving from researchers rather than because of any manipulation of independent variables. The Hawthorne experiments took place from 1927 to 1933 in the Hawthorne plant of Western Electric. They wanted to test scientific management. The experiments were held by Elton Mayo‚ and a few of his colleagues. The experiments began as a series of productivity studies from

So if you want to try just do what we did. That is our experiment. Why this happened because the Alka-seltzer had a chemical reaction beacuse of some powder on the outside of the alka-seltzer so the bubbles carried the food coloring up to the top of the bottle
