Lab report Question and 2 on page Question 2 Assuming friction is negligible But according to Newtons second law
Question 3 Pg. 3
For an elevator accelerating upwards
F= m(g+a)
at 1 sec, the acceleration is given as = = 4 m/s2
F= m( g+a)
=60Kg*(9.8 + 4)m/s2 = 828 N
b) F= m( g+a)
but at 4s, a=0 therefore
= 60 *9.8
= 588N
Therefore, 60Kg*10 m/s2 = M * 4 m/s2
M= 150 Kg
c) F= m( g+a)
at 8 sec, the acceleration is given as = = -2 m/s2
F= m( g+a)
= 60Kg(9.8-2) m/s2
= 468N
Question 8 in page 6
The graph of acceleration against time has thre same shape as the graph of Force against time. This is because mass is constant and therefore the two graphs differ by a factor equivalent by the mass of the body investigated
Question 10 page 7
The graph is not linear because mass of the body used must always be constant wheas the force always changeds because of variation of gravitational acceleration with position, time and the conditions in which the expriment is conducted.
A short conclusion based on table 1 on page 8
According to the results in Table 1, the higher the acceleration of the elevator the higher the normal reaction registered. For example, a normal reaction of 704N corresponds to aa acceleration of 1.2m/s^2 whereas a normal reaction of 616 corresponds to a -0.128m/s^2 acceleration. For zero acceleration, the normal reaction remains constant as shown on the table 1.
Conclusion 1 and 2 page 16
Newtons laws find many applications in the life experiences for example, rocket and jet propulsion in which the third law is widely applied, garden sprinklers, firing guns, dynamic lift and balances of forces in helicopter among many applications.
The major limitations of Newtons laws in motion is that they cannot be applied in objects travelling at the speed of light. Additionally newtons laws fail when they are applied to very small objects such as atomic and subatomic particles in which they fail in the concepts of quantum mechanics (
The free body diagrams enable one to set the problem properly and solve for the unknown forces that act on a body in real life situations. ( diagrams learnt in this Lab are useful in understanding what is likely to happen to a body before applying the equations of motion. The distance time graphs are very useful in approximating various quantities such as the possible time one can take to travel from one place to another, the critical velocities and acceleration necessary to avoid accidents and crashes. Additionally, one is able to understand the conditions feelt when one uses an elevator system and the manufacturers of the elevators apply the knowledge while making and installing elevators.

Psychological Analis of Sex Offenders

...? Psychological Analysis of Sex Offenders of Affiliate Registration of sexual offenders is important since it deters offenders from repeat offenses, protects communities from the offenders and assists authorities in keeping track of the offenders. The federal codes with regard to registration and/or publication of offenders are just guidelines and the stated are mandated to construct their own legislations. The state of Minnesota has its own legislations which include the Minnesota Statute 243.166 and Community Identification Act. Over the years questions have been raised regarding constitutional challenges and concerns. Introduction Over the years the approaches to legislations governing the registration and the publication... Psychological...

Expression Of Recombinant Tick Histamine-Binding Protein

...?EXPRESSION OF RECOMBINANT TICK HISTAMINE-BINDING PROTEIN TC11485 FROM Rhipicephalus microplus USING PPICZ-ALPHA IN Pichia pastoris Histamine-binding proteins (HBP) are ubiquitous biomolecules with pharmacologic importance, since they have an immunosuppressing activity, which can help prevent adverse health conditions such as histamine shock. To facilitate further studies regarding the structure and function of HBP, there should be an efficient means by which HBP can be made available. For this, Pichia pastoris expression system was assessed for its competence in producing recombinant HBP. This was chosen for its effectiveness in glycosylating recombinant proteins. On the other hand, the HBP gene sequence used for this particular... OF...

...? Item Analysis: Estimating the association between two quizzes and two psychological variables Results The researcher wished to test the hypotheses that student performance on the two quizzes administered during the semester was associated. Additionally, the researcher was also interested in testing the association between two psychological attributes, emotional intelligence and happiness. Finally, the researcher wished to determine whether emotional intelligence and happiness might be correlated with quiz II performance. Before testing these hypotheses on the data gathered, basic psychometric analyses were performed on the quiz items for both quizzes as well as for the items on the happiness and emotional intelligence scales...

Reflection and Evaluation of Technologies Such As XML and Flash

...?XML There are those who believe that Extensible Markup Language or more commonly known as XML is the most exciting technology today as it supposedlyinteracts with most organizations globally, with the omnipotence of the Internet technology. This could be true because XML is a computing language that is designed for the simple and fast use and access of information on the Internet, an important objective that could spell tremendous productivity, and, for enterprises, potentials for profitability. It is mainly a platform for documents and textual data using the Unicode standard, which effectively encodes, represent and manage majority of the languages of the world. One will find that XML documents are primarily constituted by texts...

Case Analysis Part IV

...? CHAPTER 16 CASE 7 I believe that the Bank was not right in this case. The key moment in National Exch. Bank v. Mann is establishing whether the moment of passing the title of property from the seller to the buyer depends of the transmission of the title certificate. The Court has to explain if nondelivery of the certificate means nondelivery of title of care. Under the Wisconsin counterpart of N.Y.U.C.C. § 2-401 (2) “Unless otherwise explicitly agreed title passes to the buyer at the time and place at which the seller completes his performance with reference to the physical delivery of the goods, despite any reservation of a security interest and even though a document of title is to be delivered at a different time or place…”1...

...?Introduction Coral Reefs: Coral reefs are the most diverse and beautiful of marine habitats and are also known as "Rainforests" of the ocean. The formation of reef structures is aided by algae that are symbiotic with reef-building corals, known as zooxanthellae, Coralline algae, sponges, and other organisms. One of the most dominant is the sea anemone Aiptasia pallida, members of the phylum Cnidaria, which contains zooxanthellae. It is dark brown to translucent brown in colour. The brown colour comes from zooxanthellae. They’re ecologically important and have a high biodiversity, which serves as a storage of rich genetic resources. Coral reefs are found in about 100 countries and are home to over 25% of marine population... Coral Reefs:...

Processing-structure-property relationships in (TPE-E) nanocomposites

...?4. Results and discussion The present work describes Fluormica (Somasif ME 100) Prestine clay modified with alkyl-ammoniums and a polymer (PolyesterTPE). The goal was to prepare TPE-E nanocomposites by preparing modified organoclays and melt blending them with different grades of TPE-E (Block copolyester thermo platic elastomers)using extruder (PolyLab ThermoHaake). There is a significant amount of polymers that the produced modified organoclays can be blended with. Modified organoclays are known to be highly dispersible in both polar and non-polar polymers. However, we will use only Polyester TPE of three different grades (Grade: Hytrel 3078, Hytrel 4069 and Hytrel 5556). This area of research is extremely promising because... Results and...
