Energy and Kinematic Experiments: Sources of Errors Introduction Theoretically, energy and kinematic equations should give ideal relationship between variables under study. However, data obtained from empirical procedures are not 100% accurate. Always, experimental errors accounts for the deviation between theoretical values and empirical data. After completion of a physics experiment, it is appropriate to carry out error analysis exercise. Such analysis exercise facilitate comparison between theoretical values and experimental values; hence ascertaining the level of experimental precision and accuracy (Arlene 37). This essay appraises possible errors encountered during the energy and kinematic experiments. Sources of errors include;
One procedure during the experiment involves measuring the horizontal distance travelled by the block after being released from the top of the inclined plane. In this context, there were possibilities of parallax error. Parallax error results from the distance between the observer’s eye and the measuring scale. Parallax error occurs whenever the observer’s eye fails to squarely align with the scale. Therefore, there is a possibility of parallax error when measuring distance ‘x’ travelled by the block.
Stop Watch
Systematic errors usually occur whenever observation features as one procedure used in collecting experimental data. Technically, it is almost impossible to start and stop the watch at precisely the ideal moment in time throughout the experiment. With respect to the experiment, stop watch error may have affected all the five entries of time. In this regard, it will be accounted as a constant systematic error throughout the experiment.
Instrument Resolution
Typical instruments like rulers will not lack resolution errors. In the energy and kinematic experiment, values obtained for distance ‘x’ contains instrument resolution errors. The ruler used had finite scale, thus limiting the ability to precisely obtain small measurements. Conventionally, electronic meters would measure slight adjustment in distance (Arlene 41). However, precision and resolution of rulers are limited by the finite scale, and cannot measure fractions of a millimeter.
Physical Variations: Using different side of the block
In physics experiments, precision of procedures is important in ensuring accuracy of data obtained. For repetitive procedures, changing a physical aspect like reversing one side of the block will cause a substantial error in reproducibility. When combined with other errors, physical variations cause considerable imprecision of empirical values.
In conclusion, it is undeniable that numerous types of errors are responsible for any deviation between experimental findings and theoretical predictions. Acknowledging and analyzing these errors not only helps in explaining the deviation but also enhances learning and experience for future experiments.

Iodine 131 properties and usages in Brachytherapy

...28th March 2007 Iodine 131 Properties and Usages in Brachytherapy Iodine 131 is a radioisotope of iodine. It is an artificially created isotope that is used for therapeutic uses. It is also known as radioiodine (131I). It has a half-life of 8.0197 days emitting beta and gamma radiation. An atom of iodine has 74 neutrons and when it decays it forms 131Xe. Iodine 131 is produced by the fission of uranium atoms during the functioning of nuclear reactors and also during the detonation of nuclear weapons where uranium or plutonium is involved. One of its most important uses of iodine 131 is in nuclear medicine, especially in radiation therapy where it is used to treat thyroid...

Article Critique on article critique on Preferences for Friends and Close Relationship Partners: A Cross-Cultural Comparison. that I found in Academic Search Primer. Journal of Social Psychology, Aug 91, Vol 131 Issue 4, p579-581

...SUMMARY OF THE ARTICLE The article under the “Preferences for Friends and Close Relationships Partners: A Cross-Cultural Comparison” has beenwritten by Goodwin & Tang. It reveals the very fact that researchers and psychologists have been interested for nearly five decades in discovering the characteristics individuals seek in lovers and friends as well. Buss has measured such attributes with reference to cross-cultural differences in his research in 1989. Bond has made his research on the subject by a comparative analysis of two different nations based on the questionnaire prepared by British and Chinese students identifying attributes both for lovers and friends. The research based on two parts of questionnaire i.e. preference... OF THE...

The Sociological Imagination SOC 131

...The Sociological Imagination SOC 131 Sociology is simply the scientific study of human interaction, culture, and belief systems. There are three different types of sociology—basic/pure, applied, and clinical sociology. We should study sociology because sociology looks beyond the individual. Group dynamics are a large part of sociology because humans are naturally social and like to do things in larger groups. Also, the study of sociology can identify problematic behavior and help to prevent it from occurring. According to C. Wright Mills, the sociological imagination is our capability and motivation to see the associations between our personal lives and the social world in which we live. In the Jakarta Post, Achmad...

SOCI 131-Introduction to Sociology

...The norms of a culture are the tacit expectations or imperatives that guide individual behaviors in situations within that culture. Norms are a helpful way for individuals within a culture to understand and categorize behaviors of others. When one comes across someone from a different culture, with different norms, or an individual supposedly from the same culture but is “deviant,” it is much more difficult to understand, categorize, and contextualize that behavior. Members must conform to the norms of a culture for that culture to exist and play a functional role in the lives of its members. Therefore, it is problematic for those who are deeply embedded in a culture to accept or even acknowledge the deviance of some people... norms of a...

Plant phy

... Plant physiology Plants have a cell wall on both sides of plasmodesmata (PD) that facilitate cell-to-cell transport of micro- and macromolecules, consisting of plant viruses, RNA, metabolites, and proteins. According to Stonebloom et al (191), PD ultra structure is determines PD transport ability; nearly all PD in developing tissues has a single medium, which permit larger molecules to pass through the cells, whereas the severally branched PD in older tissues restrict large molecules. Studies show that cellular redox state control intercellular transport via plasmodesmata (PD). However, this connection has been imprecise as increased production of reactive oxygen species (ROS) links with both increased and decreased intercellular...

Phy 155 Assignment

...Physics 155 Assignment Physics 155 Assignment Question1 The earliest notable form of GUI was the Augmentation of Human Intellect project developed by Doug Engelbert in the 1960s. This included a mouse driven cursor and several windows, working on hypertext. In 1973, Xerox PARC was developed as the first computer window which demonstrated the graphical user interface characteristics (Nielsen, 1993). This product was however not marketed as a computer interface because it had not been registered commercially and was private property. The usage of the product remained limited to personal computers although many units were manufactured and heavily used in the company offices and several universities. Another factor was the market... 155...

...of the mathematical edifice of linguistic expression for numerals. In this case, “base” connotes a scenario where the numeral system is expressed as “n” raised to some numerical expression such as xn + y (Dryer et al. 131). With regard to this, world languages are divided into various categories including; decimal, pure vigesimal and hybrid-vigesimal decimal. Apparently, French is classified among the decimal system where numerals are expressed as shown below; Quatre-vingt-dix-sept (four-twenty-ten-seven).
