: Let’s now start by looking at the basic requirements for selecting materials that are suitable for a particular application. For example figure 1 shows a connecter joining electric cables. The plastic casing has been partly cut away to show the metal connector. Plastic is used for the outer casing because it is a good electrical insulator and prevents electric shock if a person touches it. It also prevents the conductors touching each other and causing a short circuit. As well as being a good insulator

potential of this nature is allowed to unfold then the optimal personal development will follow. Firstly this essay will define Rodgers main concepts clearly. Secondly it will relate the concepts to the depiction of Precious’ life story as seen in the film. Lastly it will argue that Precious’ does depict self- actualisation. The Self- Actualising tendency is defined as the ‘self’ which emerges from the ‘perceptual field’ that expresses one’s ‘self actualising tendency.’ This tendency is an inherent

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity

conducting surface with a thin layer (seldom more than 0.001 in [0.025 mm] thick) of metal by electrolytic deposition. In electroplating‚ the object to be plated is made the cathode in an electrolytic bath of salts of the metal to be plated. The anode may be an unaffected metal‚ or‚ more commonly‚ the metal to be plated. An electriccurrent is passed through the solution‚ which results in the deposition of a thin metal plating in the desired thickness on the cathode. Traces of organic materials are usually
