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)

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

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
