ENGL 1515 ASSIGNMENT “TELEVISION” BY ROALD DAHL: AN ANALYTIC REVIEW NAME : NUR AFIFAH BINTI NOR HASBI MATRIC NO : 1416044 SECTION : 1 LECTURER : DR. MD. MAHMUDUL HASAN Television has been playing a major part in our lives since its first debut in the middle of the 20th century. It has been the leading means of entertainment with a wide range of viewers from little children to the elderly expanding from Asia to North America in the past five decades since it has been popularized…

For many Americans TV is essential for life. Like water it is something that is needed to go throughout the day. But, what is the effect that this is having on one’s mind, body, and family? Is the joy of the television for those 5 hours’ worth it? TV has many effects that do not benefit American culture; this includes bad health, not being productive, the thought processes one has. Watching TV is bad for one’s health. So many Americans have been turned into couch potatoes. Figure one is…

Phosphorus recovery in MEC When the pH of the cathode chamber reached 8, P started to precipitate as struvite. The reactor accomplished a peak precipitation efficiency of 94%. Recovery of P was in the cathode chamber, where the neutral solution was converted to alkaline by proton consumption. Previous studies reported similar results, like Cusick et al. (2014) and You et al. (2016), where high P removal was carried out by MEC (85%) and MFC (82%), respectively. Cathode pH was affected by…

One of the most important experiment in the discovery of electrons was the Cathode Rays tube. The above experiment reveals bright lines are observed to come from the cathode, negative electrode also known as Cathode Rays. Before there were many controversy over the nature of cathode rays. Many German physicists thought that cathode rays was some form of radiation while most of British physicists believed that the Cathode Ray was a stream of negative charged…

resistivity (V/R=I) and thus, in an electrochemical cell. If the resistivity is doubled, and all different factors stay constant, the quantity of corrosion is cut in 0.5. 3) Contact Resistance The contact resistance of the anode to electrolyte and of the cathode to electrolyte is a component of the overall corrosion cell resistivity—the lower the contact resistance, the greater the corrosion current. As the contact resistance increases, the corrosion cell current will decrease. The decrease will…

activity increase. Both sides accelerate the cathode reduction and crystallization of metal ions. Considering the change on interfacial energy, the most conducive shape to form the two-dimensional nucleus is the cylinder. Suppose that the cylinder nucleus, radius r and height h, is the same high to an atomic, then the variation of critical free energy that formed the two-dimensional crystal nucleus of the metal atoms and stably existed is ∆G_c. If the cathode overpotential is very serious, ∆G_c…

Experiment. The outcome of this experiment was JJ’s discovery of the electron. CRT is an acronym for Cathode Ray Tube, this gives a broad concept of what the experiment is about. The basic components of the experiment include, a glass cylindrical tube with most of the air inside vacuumed out of it, and inside the tube is Electrode for each side. One of the Electrodes is negative and entitled the Cathode, while the other one is positive and entitled the Anode. For the experiment to work the two…

A Battery (Electricity) is a device that makes electric current through motion of cells which are the components of the battery. They are devices that convert their inner chemical energy into electrical energy. A battery has of two or more cells which are connected together in order to give out electricity. Batteries are commonly used in single cells such as the ones used to power radios, watches and small electrical appliances that are used in everyday life. They are also used to supply energy…

removes material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The current is passing through the system of arrangements will cause the dissolution of anode. This process of…

This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…
