Freshman Physics Name:_________________________________ Per:____ LAB: Marble Launcher Due Date:_________________ You have learned that the motion of any object moving through the air affected only by gravity is an example of projectile motion. Examples of projectile motion include a basketball thrown toward a hoop‚ a car driven off a cliff by a stunt person‚ and a marble launched from the CPO marble launcher. Toss a ball some distance and you can imagine in your mind the arc it follows

The reaction order‚ based on the rate law‚ was first order with respect to crystal violet and second order with respect to OH-. The rate law was as follows: Rate law = k [CV]1[OH-]1 where k equaled 2.61. In order to determine the reaction order with respect to crystal violet‚ the graph that described the relationship between ln[CV] and time (seconds) was Figure 2. Not only did Figure 2 generate a more linear relationship‚ but it had the highest R2 value of 0.992 than ([CV] versus time) and ([1/CV]

meter (N/m2)‚ or pascals (Pa). 3. Slowly drag the temperature (T) slider back and forth. (Note: In this Gizmo‚ the Kelvin scale is used to measure temperature. On the Kelvin scale‚ 0 degrees is absolute zero‚ the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? __If the temperature is colder the molecules move slower and if the temperature is hotter the molecules move faster.

true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip’s. It has many disadvantages when it is used in power electronic applications‚ such as bulk in size‚ slow operating speed etc. Carbon‚ Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors in normal temperature. So in the earlier days they are used widely

The marble statue of Diadoumenos is a copy of the original bronze statue displaying a young man tying a fillet around his head. The original was created in c.a. 430 B.C. by a man called Polykleitos of Argos. Polykleitos was a Greek sculptor who worked during the mid-fifth century B.C. . he was one of the most famous artists of the ancient world. Polykleitos’ figures are carefully designed with special attention to bodily proportions and stance. The statue of Diadoumenos has its thorax and pelvis

The Elgin Marbles / Parthenon Sculptures I read two articles on the internet that provided some very interesting points in regards to the “Elgin Marble” which are better known as the “Parthenon Marbles.” Between 1801 – 1805‚ Thomas Bruce‚ Seventh Lord Elgin‚ procured the marble art and took them to Britain. Lord Elgin’s original intentions were to obtain some sketches and plaster casts made of the great sculptures and reliefs on the Parthenon and other nearby ruins. At the time Greece
