Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior

The rock cycle is very important to us because it explains the way the different types of rocks are formed on earth. Geologists classify rocks in three groups‚ depending on the Earth processes that made them. Some rocks are formed by heat and pressure. Other rocks are formed by weathering and erosion. The three rock groups are igneous‚ sedimentary‚ and metamorphic rocks. Igneous rocks are formed from melted rock that has cooled and solidified. They can form underground or above ground. Underground

by Dr. Wendelin Wiedeking. They may simply agree with current leadership and therefore remain quietly complicit. What this means for minority shareholders is that they do participate in the distributed profits and any and all capital gains (losses) which the traded preference shares provide‚ but they have no voting rights and therefore no ability to act as owners in whole. It also explains in part the company’s relatively uncooperative response to the requests of analysts and stock exchanges for more

Hot tap operation is a combination of many variables‚ welding is only one of them‚though it’s critical for any hot tapping operation. Note Hot Tap could lead to serious fatalities if not done properly. Since you mentioned about Shell’s DEP‚ please note these DEP’s are well respected in the industry. That does not mean what’s written is absolutely unquestionable‚ but there’re good rationale on what’s written in the DEP’s.

enter the real life and competitive world of industries where there is cut throat competition. In order to exist in the competitive world one has to be fully aware of all the aspects of industrial life. My summer training for 45 days at Milan granite was an eye opening experience for me. During the course of my training I have learnt to correlate the practical problems and situations to the possible theory knowledge. It is a proven fact that bookish knowledge is not sufficient because the thing

Nowadays‚ Australia is the most attractive‚ exotic and vibrant tourism destination. Thousands of tourists explore the wonder attractions and experience an extreme climate in Australia. This essay will contrast the Australia’s weather and natural features with a different fascinating continent such as South America. Firstly‚ the Australia’s weather shares similar conditions with South America. “ Australia experiences temperate weather for most of the year but the climate can vary due to the size

The question being addressed in this lab is which ingredient will produce the most bubbles? If baking powder‚ baking soda‚ and salt are added to different test tubes of sugar water‚ then baking soda will have the most effect on the rate of fermentation (create the most bubbles). This hypothesis is rejected. Based off of data‚ the hypothesis was rejected. The ingredient that produced the most bubbles was baking powder. In the experiment finishing at 20 min.‚ the control had 2.5 cm of bubbles produced

A joint is defined as a fracture in a rock between the sides of which there is no observable relative movement. They are present is most consolidated rocks of igneous‚ metamorphic and sedimentary origin. Joints may form as a result of either diastrophism or contraction. Description: (i) A series of parallel joints is called a ’joint set’. (ii) Two or more joint sets intersecting each other produce a ’joint system’. (iii) Two sets of joints nearly at right angles to one another‚ produced by the

Which pressure groups are the most powerful? Some pressure groups are clearly more powerful than others. Some succeed while others fail. But what does ‘success’ mean? How can we weigh up pressure-group power or influence? These are difficult questions because ‘success’ may be measured in different ways. Success may mean: * Affecting government policy – policy-making power. * Pushing an issue up the political agenda – agenda-setting power. * Changing people’s values‚ perceptions and
