National Diploma in Mechanical Engineering Section A: COMPULSORY Answer ALL questions 1-12 1. A resistance temperature device has a resistance R0 = 100 Ω at 0o C. If the resistance RT = 197.7 Ω in an oil bath‚ what is the temperature of the oil in the bath‚ given that RT = R0(1+αT)? Take R0 = 100 Ω R0 = resistance at 0o C α = 3.9083 x 10-3 /o C (2 marks) NDE Thermodynamics and Heat Transfer Exam 2008 Name: _______________________________________ Read all the instructions before starting Do

The current understanding of knowledge and the universe by man today stems from many centuries ago when philosophers attempted to understand the seemingly chaotic world around them. The Greek philosophers Plato and Aristotle are responsible for some of these major early discoveries and are a big reason as to where we are today due to their endeavors to understand various philosophical topics. In this essay‚ I am going to explain Plato’s views on knowledge and science‚ Aristotle’s views on change

Just because of your 50 years old‚ doesn’t mean that you don’t like the same thing as let’s say a 29 year old. Or because you have a dark color of skin‚ or a white skin‚ we all are the same on the inside‚ and that’s all that matters. The only way we define ourselves is the way you act in life‚ if

functions. They both serve as mechanisms for cell division. However‚ quite significantly‚ they are very much different in fact and occur in different situations. Mitosis and meiosis take place in different places. This is one of the first major differences between the two. Mitosis takes place within somatic cells (cells that make up the body)‚ while meiosis takes place within gamete cells (sex cells). As such‚ meiosis produces more gamete cells‚ and mitosis produces somatic cells. Mitosis is the process

Love and Marriage are Separate Love and marriage are hot topics in all ages‚ let alone in modern society‚ for they concern every individual. In recent years‚ the relationship between them is becoming increasingly complicated. Marriage or love means differently to different people.
