conditions impacting the motion of the bottle rocket in the the x and z planes. This therefore potentially resulting in an effect on the motion of the bottle and the height data recorded at an unknown level; as opposed to that in theoretical conditions. Moreover, incorrect initial scaling of length measurement on the data analysis soft-wear, could have resulted in incorrect heights being deemed to have been reached by the bottle rocket. The nature of the freeze frame data analyzation on Pasco…

limitations in the SERVQUAL instrument, various other researches have adapted the model to suit other areas of service quality. Bojanic and Rose (1994) used an adapted version of SERVQUAL for the purpose of looking into chain restaurants with a higher level of diverse customers and a varied menu. Stevens, Knutson and Patton (1995) revised the SERVQUAL instrument and developed a similar model called DINESERV, which is used to understand customer’s perceptions of the quality of service offered by…

made at the end. In the first half of the experiment, the density of copper is calculated using two different methods of measurement. The objective of the experiment was to compare the two techniques and decide which one was more accurate. The density of copper is 8.96 g/mL (Copper 1). The average density calculated…

Introduction This practical was an investigation involving the use of a tennis ball and a meter ruler. The tennis ball was held and dropped at a specific height above the ground. The height of the bounce was then measured. This investigation was carried out to find out whether the efficiency of the bounce varied with the height of release of the tennis ball. If the bounce were 100% efficient, then the tennis ball would have bounce off the ground and return to the starting height. Research…

Throughout scientific studies, researchers utilize sampling and conduct research that identifies probability and nonprobability, reliability, and validity of research. Also, scientists utilize telephone surveys, online surveys, focus groups, and surveys via websites when collecting data for research and need to be aware of the advantages and disadvantages of each of them. Sampling is the process of selecting a small part of a population for inspection and utilizing that smaller part of…

is directly proportional and that the small difference is due to systematic errors in the practical. Errors Random errors: A random error is an error in which its effect on measurements vary in each trial. Hence this type of error has an effect on the precision of data. Precision is how close together a set of measurements are regardless of how far away they are from the true value.…

placebo-controlled, randomized, and double-blinded, which reduced the variability in results. The extended 10 week β-Alanine supplementation in 8 subjects allowed to examine the extended effect of β-Alanine; during this time, the doses increased. Baseline measurements were recorded prior to, during, and after…

Abstract The value for the acceleration of gravity was measured in this report through the investigation using three different methods, each varying in accuracy, to calculate the period of a pendulum. The period was measured by repeatedly timing the time it took for the pendulum to return to its original position once it was swung from a certain point (for the first method one oscillation was timed, however in the second and third ten oscillations were timed and the overall time was divided by…

motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations. Results/Data Part 1: The Motion Sensor Motion Sensor’s Measurement of Distance on ‘Short Range’ 1 m Closest Measurable Distance on ‘Short Range’ 0.12 m Closest Measurable Distance on ‘Long Range’ 0.12 m Distance from Center Line for First Detection of Block on ‘Short Range’ 0.05 m Distance from Center Line…

the skin, as it picks up electrical signals from the heart through the skin, when it beats. The data will be send then to the wrist band where the heart is displayed and the whole data is collected to review the differences during the period of measurement. (Wood, R. (2015) Measuring Heart Rate) For measuring her blood pressure she might has used an automatic machine. She needs to put her arm in a cuff – where a gauge is fixed- which gets inflated to squeeze the arm. If the cuff is fully…
