Results The diameter of the cylinder (D) is 0.01m and the length of the heater (L) = 0.07m. The emissivity of the surface was 0.95 and the Stefan Boltzmann constant was 56.7x10-9 Wm-2K-4. The room temperature was assumed to be 25°C which is 298.15K. At a trendy east London bar‚ a group of body hackers are putting forward their reasons for human augmentation to a packed audience of mainly under-35s‚ many of whom are sporting piercings and tattoos.

In his book‚ Foucault identifies the roots of sexuality back to the 1600s‚ where Christian ideology resulted in an augmented interest in sexuality within families. As sexuality began to intensify throughout society‚ ruling classes began to regulate it by seeking guidance from mentors‚ doctors and pastors that resulted in a massive dissemination of discourse on sexuality. Over time‚ sexuality has become rather significant to individuals‚ something that defines them spiritually‚ physically and socially

In the famous poem‚ Root Cellar‚ author Theodore Roethke uses immensely visual and sensory images. The reader not only experiences going down into the cellar through the intense description‚ but also through the imagery‚ along with a few powerful similes that give life to the root cellar’s contents and creates a sense of awareness for the reader. In the first line‚ the words “dank as a ditch‚” are an example of a simile that brings some clarity to the cellar because now there is something to compare

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly
