Physics Essay

Discuss the methods and technology used in damping buildings when resonance leads to SHM caused by the wind and earthquakes
Damping in tall buildings is mainly caused by intrinsic and supplementary sources. Intrinsic damping comes from connections, cladding, friction and seismic motion; in this case, this paper is interested in the seismic causes of the damping which is earthquakes. Supplementary damping is due to engineered devices such as friction devices, viscous and slosh dampers and tuned mass dampers (Katsuhiko, 2005). There are broad methods that have been largely used to control damping;When a building has

Debate Question
As Barney Frank said, space exploration is of immense significance. However, sending men to the Mars and back to Earth will cost Americans hundreds of billions of dollars yet bear little worth. In 2013, the government spent over 4 trillion dollars. While only 0.5% of this went into funding NASA, it disturbs the mind why so much money should be used on exploration of the space while a little less than that could influence so positively in making the lives of people better on earth. Spending

Digital Design Project
Students do mini-projects to understand better the functions of circuits. Treatment of data type’s hierarchies in hardware description of digital designs and formulations of the first order algebraic equations have been done is researches to understand logic synthesis. In another study by Sagarika Pal and Niladri Tripathy, remote angular position control system of stepper using DTMF technology as an optional means of communication for controlling means of communication was used to implement

Describe how the motion of a mass-spring system can be used to describe the oscillation of air molecules and longitudinal sound-wave propagation
The answers for this comparison of movement takes the structure where xm is the abundancy of the swaying, and φ is the stage steady of the wavering. Both xm and φ are constants dictated by the starting condition (intial uprooting and speed) at time t=0 when one starts watching the oscillatory movement.Longitudinal waves are waves whose energy transfer is in the same direction as the displacements in the medium in which they propagate. In addition, they can have one or many pulses. They have

Drugs binding
And development of new drugs is a complex and expensive enterprise, which requires the inter-play of several scientific facets through integrated multi-disciplinary teams. The key roles of the computational chemistry within this multi-disciplinary team have become firmly established. Metric points to the measurable effect of computer-aided medicine design across a discovery timeline. More recently, computational drug chemists have a wide range of chemical databases, informatics and silicon

Deep Sea Drilling: Should the US allow offshore/deep-sea drilling for oil?
For example, environmental specialists will be hired to ensure that drilling doesn’t upset the ecosystem balance (Zabanbark, 2009). Technical experts will be involved in the entire drilling process to increase its efficiency and cost effectiveness. Financial analyst will be required to analyse the logic of drilling and determine if the drilling costs exceed the benefits of drilling. In addition, increasing the oil reserves will increase the energy levels and increase industrialization. Growth

Development and new trend of holography
With a coherent light source and a definite geometry or a short pulse period, the interference pattern is at a stands till and, hence, can be recorded into the hologram’s photosensitive suspension. Afterwards, the hologram is chemically developed to a point where the suspension acquires a modulated density, which freezes the inference pattern into fringes. When observing the modulated structure under a microscope, it appears different in comparison to the image encoded within. The density

Discussion the physics of collisions
Since both vehicles were initially in motion, the Kinetic Energy approach will be used to determine the work done to bring the car to a stop. The Kinetic energy K due to the motion of the car of mass m and speed v is given by;Kinetic energy was converted to heat energy in the tires, the road, and the air when the car skidded to a stop. This conversion is as a result of the work of Friction W. Work done is given by force f times the distance d. In this case,The mass of the 1988 Chevrolet Cargo
