The measured tensions were normalized relative to the maximum tension and the lengths were normalized relative to the length at which maximum force was generated (Ln = 29 mm). The measured data and expected data were plotted together (Figure 3). Correlation between measured and expected tensions at the same normalized lengths was determined for the three expected segments of the length-tension relationship.2,3,4 This was done using piecewise linear regression and yielded r2isometric = 0.956033. The fitted curve for the isotonic experiment resulted in r2isotonic = 0.960557. The F0 was 19.5 N for the fit and 6.35 N for the guess.
2 Keeping your upper body and shoulder in place, roll your forearm so your palm faces upward. When you can go no farther, use your opposite hand to help roll it more upward until you feel a gentle to moderate stretch. Hold for __________ seconds. 3 Slowly release the stretch and return to the starting position.
Fill beaker with water Use the disposable pipette to place water in the graduated cylinder until the unidentified object would be completely submerged in water Record what the measurement of water in milliliters before placing the unidentified object into the graduated cylinder Gently place the unidentified object into the graduated cylinder Record the measurement of the water in milliliters after placing the unidentified object into the graduated cylinder Subtract the measurement of water in milliliters before placing the unidentified object into the graduated cylinder from the measurement of the water in milliliters after placing the unidentified object into the graduated cylinder, this is the volume of the unidentified object Record the volume (the answer you got in step 10) of the unidentified object in the data table Weigh the unidentified object on the scale, this is the mass of the unidentified object Record that number in the data table Calculate the density of the object by dividing the mass by the volume and rounding it to the proper significant figure, Record the density of the unidentified object in the data table Repeat the lab 2 more times and with each experiment record the data in the chart under the correct trial number corresponding with the correct
This experiment is called jumping Pop Rocks. You first fill a glass with water that is 140 degrees fahrenheit. Then you pour the Pop Rocks into the glass. Since the Pop Rocks are infused with carbon dioxide they will tend to jump at the bottom of the glass, or maybe even reach the top of the glass once they dissolve.

Background: In Ischia Island the water around the island has been acidified for millions of years because of Mt. Vesuvius. This dormant volcano is melting chalk in the sea floor, which releases carbon dioxide into the water acidifying it. This acidification is devastating the life around the island and is still being acidified by the continuous release of CO2. We can use this as an example of what our world might look like if we continue to release carbon dioxide emissions through things such as burning fossil fuels and reducing the carbon banks such by things like deforestation.
The specific motion used for this analysis is a baseball pitch by Jake Arrieta who plays for the Chicago Cubs (https://giant.gfycat.com/BelatedWeirdKookaburra.gif). His characteristics: male, height is six foot four inches, weighs 225 pounds, pitches and bats with right hand, age is 30 years old, and has been playing for seven years. In order to produce enough force, the pitch has to go through multiple phases in order to generate it.
1. From Jason Johansen 's Notes on Chicano Cinema, scholars of Chicana/o cinema used to identify the criteria of Chicana/o cinema as "films BY Chicanos, films FOR Chicanos, and films ABOUT Chicanos" (Johansen 303). The Salt of the Earth film (1954) attempts to expand this definition because it achieves more than being for and about Chicanos, it can also be for other minorities fighting injustices and inequalities similar to Chicanos. The film is still for Chicanos because it illustrates an actual account of Mexican American mining workers in Zinc Town of New Mexico during World War II, where the union workers won due to their unity, inspiring others to stand with each other in the Chicano movement. The movie also challenges the criteria because it is a film directed by a non-Chicano, Herbert Biberman, but that inadequacy was compensated since most of the actors were local Mexican-American union associates who had experience and direct involvement in the historical fight for their rights.
In the lab “All That Glitters” the objective that was focused on during the lab was calculating the density, volume and mass of various substances. The method that was used in finding the volume of the samples is called the displacement method. This is a process where the volume of the water in the graduated cylinder is calculated before and after the sample is placed. In this lab, the goal of the experiment was to identify and come to consensus about what the unknown substance might be. For this experiment, the required materials were ten pre and post pennies, unknown sample, graduated cylinder, weigh boat, water, paper towels and a weighing scale.
Each group was assigned a different percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass.
Physics, period 3 Malak Mokhles Data collection: Jan To measure the period of a swinging stopper for three selected radii in order to calculate the centripetal force Data Table Calculations Calculate the centripetal force acting on the stopper.

Second, the experimenters has to fill up a measuring cup until the water reaches 200 mL. Third, the experimenters will fold the paper towel in half three
When the ball hits the ground its kinetic energy is turned into elastic energy this makes the ball flatten out. Then that elastic energy is converted right back into kinetic energy when it goes up. So the more kinetic energy a ball gets when it is dropped the more energy it will have when it hits the ground which will give it more energy when it is headed back up therefore making it bounce higher.
In a world where the boundaries between real and un-real are often blurred we find that our realities often imitates the un-real more than the real. We are faced with a society where we are more in tune with the hyper real world. Hyper reality is defined as an inability off our consciousness to distinguish reality from a simulated reality, (Oxford dictionary, 2014) The concept of Hyperreality was defined by French sociologist Jean Baudrillard in his work Simulacra and Simulation, where he explored the relationship between Reality, Symbols and Society. Baudrillard states in his work that society has replaced all reality and meaning with symbols and signs and that human experience is a simulation of reality.
