Answer the following questions in the essay box below: 1.In the temperature part of the experiment, which antacid tablet dissolved the fastest? Which antacid tabled dissolved the slowest?

2.How did the temperature affect the reaction rate?

3. In the particle size part of the experiment, which antacid tablet dissolved the fastest? Which antacid tabled dissolved the slowest?

4. How did particle size affect the reaction rate?

5.Think of a way to increase the reaction rate even more. What would you do?

6.Graph the results of the experiment.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Which of these has some mechanical energy? a. an atom b. heat inside earth c. a book on a shelf d. the fire from a lit match

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
