Besides, the mode of reading especially approximations and positioning of a person’s reading view could have also contributed to the errors. Table 1 Value of error = 0.354 Table 2 Percentage error = 1.96% Applications Knowledge concerning diverse measurements and their quantities is a very essential especially in fabrication sectors, for illustration, engineering besides other normal human activities. Calculations Measurement of Length, Mass, Volume and Density Introduction Measurement is an essential aspect mainly utilized in the scientific field to quantify diverse forms of matter. This entails determining the objects’, quantity of matter, volume and their densities (Wilson & Cecilia 242). However, an object’s exact measurement despite one being an expert, accuracy mainly relies on the equipments a person utilizes to take diverse measurements. This is due to the imperfections, which result from the equipments’ errors while a researcher is taking measurements of different types of matter or their parts. Therefore, it is essential for the researcher to have adequate knowledge regarding how to minimize errors via being able to manipulate the readings one attains while measuring. Since this varies across the equipments, where some are complex especially if one lacks proper knowhow regarding particular equipment (Wilson & Cecilia 39). The study’s focus encompasses measurements of diverse objects coupled with determining their lengths, mass, volume and densities. Objective: The core purpose of this study is to measure diverse objects’ lengths, masses, which will be essential in computing their volumes and densities by using diverse measuring equipments. Apparatus Triple beam balance English ruler’ Metric ruler Vernier Micrometer caliper Three cylindrical diverse metal rods Aluminum Brass Iron Length of a copper wire Method 1. The initial step was to take the readings of a copper wire with the help of a metric ruler. This is by placing the wire on the metric rule, reading the positions of the two sides and estimating the readings to approximately tenth of a millimeter. Then developing four sets of independent measurements to approximately 0.01cm in centimeters by estimating using diverse parts of the meter rule 2. The estimation of wire’s length to a tenth inch was by the use of English ruler. This entailed using diverse sections of the ruler coupled with developing set of four independent measurements. 3. The diameter of the copper wire was measured with the aid of a micrometer caliper where the measurements’ approximation was 0.0001cm. To increase the accuracy of the study, it entailed obtaining six independent recordings in a table. 4. Individual volumes and densities’ computations followed the obtaining of fundamental measurements coupled with appropriate averaged recordings. Results Table 1 Standard deviation = v (Sum of square deviations/ (n-1)) = v (0.125/ (4-1)) = 0.2041 Value of error = 0.354 Table 2 Standard deviation = v (Sum of square deviations/ (n-1)) = v (0.0099815/ (4-1)) = 0.057681 Percentage error = 1.96% Table 5 Object used Density computed, g/cm3 Density from table IV Percent error Aluminum cylinder 2.814 2.7 6.333 ZN cylinder 7.165 7.14 1.62 SN cylinder 7.060 7.4317 5.07 Copper wire 510 8.96 1.083 Irregular solid 12.0357 12.2867 2.043 Despite the ...Show more

Density Lab Report
Density Lab Report Introduction A density of a substance pertains to an intensive property of matter which relates mass to volume, where such density equals mass (m) per unit of volume (v). Intensive properties are independent of the quantity of substance and in the experiment, Archimedes’ method of displacement ought to be employed in determining the density of a penny (Adam, 2012).

Since 19th century scientists were aware of some unique identity of an individual which distinguish from others, like finger prints. In 1970, DNA was established as key element in human life and which makes individual as unique creature. Variability in DNA sequences among individual to individual have attracted forensic experts to develop technique based on DNA to identify individual or criminal similar to finger prints.
