These P waves are able to travel through both solid rock, such as granite mountains, and liquid material, such as volcanic magma or the water of the oceans. The slower wave through the body of rock is called the secondary or S wave. As an S wave propagates, it shears the rock sideways at right angles to the direction of travel. If a liquid is sheared sideways or twisted, it will not spring back, hence S waves cannot propagate in the liquid parts of the earth, such as oceans and lakes. The actual speed of P and S seismic waves depends on the density and elastic properties of the rocks and soil through which they pass.
The insulation and the water heaters of those times was called inadequate by today’s standards. The homes and building of the present times have better insulation, the windows are sealed better and also last way longer then the windows that were around in the 50’s. The homes of today have better technology to keep the house either hotter or colder. The outside doors of the structure are now made of steel which is less drafty and also is easy to lock and secure. The homes from the 50’s had plastic and copper that would fall apart or break easier and more often, and the materials that are used today have a better
A material with a higher modulus would be able to handle forces better than a material with a lower modulus. It also means that a material that has a higher modulus of elasticity has the ability to take more stresses without permanent damage (contains more elastic properties). E = Modulus of Elasticity 3) Compressive strain is the ratio of decomposition caused by compressive load per unit length measured along the longitudal axis. It is measured when the length of a structure changes because of a compressive force. B) Torque 1) NB.
It was also because we had to take two measurements (one for diameter another for height)...which could possibly create more mistakes. Furthermore, you need to multiply diameter and height to get to the volume, so any one of those reading had a mistake, the error would compound and get worse. The same is not true with measuring with graduated cylinder, which is just a one shot reading. If that reading is off a bit, it won't impact the density as much 2- Did you find that density was intensive or extensive? Explain A- It was intensive.
Aerated concrete is also commonly known as a cellular concrete (Neville and Brooks, 2010). It can be divided into two main types according to the method of production. They are foamed concrete (non-autoclaved aerated concrete (NAAC)) and autoclaved aerated concrete (AAC). Foamed concrete is produced by injecting preformed stable foam or by adding a special air-entraining admixture known as a foaming agent into a base mix of cement paste or mortar (cement+water or cement+sand+water). The AAC is produced by adding a predetermined amount of aluminum powder and other additives into slurry of ground high silica sand, cement or lime and water.
The red colour shows basalt or whin sill. This rock is a hard igneous rock. An igneous rock is a rock formed by the result of volcanic eruption, basalt is a form of igneous rock caused by lava cooling quickly. The only reason why the waterfall is here is because of this rock. Without this rock the waterfall would not have occurred because there would have only been a less resistant rock type meaning that a waterfall wouldn’t be able to hold itself from erosion.
The reasons are multiple: technically pure metals are difficult to obtain in purified state, they are expensive, generally have low damping capacity and strength levels, unfavorable chemical and physical properties, are often difficult to handle with standard processing methods and many more. Composites are formed from composite materials, e.g. by casting, laminating or extruding. Composite material is a type of material consisting of a combination of two or more simple (monolithic) materials and in which the individual components retain their distinctive identity. The composite material has properties different from the properties of its components - the simple
This has seriously jeopardized the food supply, leaving millions in danger of starvation. “(-fao.org/news/global/GW0105.) “Not only is food scarce, but each day children as young as six are sent to collect water from taps or wells up to three hours away. Villagers say that up to 50 children have died this year due to a lack of nutrition. The drought also hit hard in the south part of the country, where British troops are fighting an insurgency.
| 1 in 5 people lost their jobs because many buildings were destroyed, Haiti’s large industry clothing was one of the worst affected, and were a lot of people lost their jobs. | 250,000 homes, 30,000 other building were either destroyed or badly damaged this included the presidents palace and around 60% of the government buildings. | Because of the large number of deaths the hospitals reached their capacity and bodies had to be piled up out on the streets. | Transport and communication links were badly damaged and destroyed, things like bridges. | The amount of bodies out on the street caused a lot of diseases to spread, diseases like, cholera.
As these two plates attempt to pass one another friction causes them to get stuck and over a period of time, pressure builds up, this pressure is released as one plate suddenly jerks past the other, with the resultant force sending shockwaves to the earth’s surface. The earthquake was caused by a slip along an existing fault in this area, the Enriquillo-Plaintain Garden fault. As a direct result of the Haiti earthquake 220,000 people were killed, while 300,000 others were injured and 1.8 million Haitian became displaced. However it was hard to treat those injured as 8 hospitals and healthcare centres in Port-au-Prince had been badly damaged or completely collapsed sue to the earthquake, as well as 200,000 homes in Port-au-Prince having been damaged. As well as this 100,000 homes were completely destroyed along with many government buildings and the presidential palace itself.
