As for the results of our tests‚ we came up with interesting findings. For the first test we conducted‚ pH‚ we came up with statistically significant results. Our p-value was .002‚ well below the .05 threshold. The control group’s mean pH was 6.65‚ whereas the experimental group’s was 6.46. This resulted in a change in pH of .19‚ making the water more acidic. As for the Q-values‚ the control group’s had a Q-value of 81 and the experimental had a Q-value of 75‚ that’s a decrease of 6‚ a significant

frequency to determine Planck’s constant John Greavu Partners: Daniel Erickson and Kevin Haar School of Physics and Astronomy‚ University of Minnesota‚ Minneapolis‚ Minnesota 55455 24 March 2014 The energy of ejected electrons from the cathode end of an electrode due to the photoelectric effect as a function of the incident light’s frequency was measured. Using the PASCO AP-8209 Photoelectric Effect Apparatus‚ an experimental value for Planck’s constant h was determined: (4.27 0.0576)

Guilt is a common feeling that humans feel when they have done something wrong. The poets Gabriel Okara and Dennis brutus both express this feeling of guilt in their personas backgrounds.

The body of both poems have a specific situation happening. in the poem “Once Upon a Time” the persona wishes to be young again an forget all the lessons

Distant stars and distant galaxies aren’t completely featureless‚ but actually has specific spectral features. When we look at their spectrum‚ we can see an absorption of spectrum. Redshift and blueshift are two different terms that describe how the light changes as objects moves closer or further away from us. The reason that these two terms can describe whether or not objects moves closer or further away from us‚ is the fact that when a certain object in space is shifted to the red part of the

Franklin Delano Roosevelt believed in saving the arts by educating the public‚ along with director Hallie Flanagan establishing the Federal Theater Project (FTP). With high expectations for the FTP to help the arts‚ it failed. With there being constant conflict between the commercial theater advocates and independent non-profit theater supports about funding‚ theaters began to slowly rise. “Hard hit by both the Depression and the rise of the cinema‚ the commercial theater had been trying unsuccessfully

When World War II ends the United States and the Soviet Union became enemies‚ better knows as the Cold War. It consisted on the constant tension between both countries in starting a war. Both sides had power in nuclear weapons which made people be afraid of the start of a nuclear war. Also both countries disagree in many things. The Soviet Union had a Dictator‚ one political party (Communist) and an economic system (socialism) in which the government run all the industries. USA had an elected president

DETERMINING THE EQUIVALENT MASS AND DISSOCIATION CONSTANT OF AN UNKNOWN WEAK ACID BY TITRIMETRY INTRODUCTION Acids are substances that donate hydrogen ions and bases are substances that accept hydrogen ions. Acids and bases react with each other by transferring hydrogen ions. One way to distinguish an acid is by its equivalent mass‚ which is the number of grams of the acid needed to transfer one mole of hydrogen ion to a base. For a monoprotic acid‚ which only transfers one hydrogen ion‚ its

How successful can the management of fragile environments be‚ given the constant and increasing demand for their exploitation? A fragile environment is an area where the flora and fauna have adapted to a specific climate and evolved to occupy many different niches due to extremely high competition for resources. Furthermore due to the constant abiotic conditions‚ specialisation and symbiotic relationships have occurred to such a degree that even the slightest ecological or environmental disruption
