During the research, there will be some demonstrations to prove that traveling waves propagate. Though, the particles of the medium are stagnant. Various properties of waves will be studied. Among the main properties of waves is the speed at which waves travel through a given medium. Wavelength is also another property of the waves that will be considered in depth and lastly the wave frequency.
Another area of research will be determining the different types of waves. The distinct properties of waves will be considered in order to identify and classify various types of waves in existence. Waves make particles of the medium in which they are travelling to be displaced. This displacement of particles affects their equilibrium positions in the medium. For a string, the particles to be displaced are either small segments of the string or its sections. Wave displacement forms a crucial while discussing about formation of harmonic oscillations commonly referred to as sinusoidal waves.
Wave speed: Taking a look at travelling waves, it becomes clear that waves have a source. A laboratory practical to analyses the source and behavior of waves will be carried out. During the laboratory experiment, a metal wire, sensor, pulley and a hanging mass will be connected as shown in the set up below.
The hanging mass is attached at the end of the string to provide tension. When a horizontal pick is used to pluck the string just at the pulley, a pulse is created in the string and travels along it in form of a disturbance. A timer is started by the pulse created in the wire by the plucking effect. The timer continues recording the time until the traveling pulse reaches the sensor, which stops it. When the mass attached to the other end of the string is changed, the ...Download file to see next pagesRead More

...Physics Introduction This paper seeks to answer a number of questions relating to physics.The areas covered include amount of wasted heat, average temperature of exhaust gas, design, amount of energy generated, and finally and estimation of the installation and maintenance costs, size, and weight of your design. 1. Estimate the amount of heat wasted on each mile from a typical car (30 MPG) Heat from any automobile is produced by burning of oxygen. The gas that is produced is carbon dioxide that is usually a product of combustion. Although there are other by-products of combustion, the main by-product is carbon dioxide (CO2). The heat that is produced will be calculated from the amount of carbon dioxide that is produced....

...? Physics Phy 1 The Law of Momentum Conservation s that without any external forces acting on a system, the moment of the system would not change (Serway & Jewett, 2009). But moving objects encounter opposing external forces and lose momentum to zero thus stopping. 2. When jumping from a tree to the ground, the person moves at constant acceleration hence constant force. On hitting the ground, the person experiences an opposing force from the ground causing the body to lose momentum within a short time interval, hence need for more force leading to pain. 3. The balloon would initially be at rest with zero momentum. On release, the gases initially inflated move in one direction and the balloon would move in the opposite...

...? Physics The universe is so large and enormous that it cannot be explained in words nor can be imagined by any one. Our earth which feels and seems to us very large is in actual equivalent to a small dust particle in comparison to the enormous universe. Universe consists of a number of different elements. The universe comprises of millions of super clusters. These super clusters consist of hundreds of different sized galaxies. Of such a super cluster is our earth a part of. The super cluster consists of galaxies in the form of groups. The galaxy in which earth is situated is called Milky Way and is situated in a group called the local group which comprises of more than 30 galaxies (Caprara & Harris, 2003). The Milky Way is made... ...

### Built environment assignment (Physics equations)

...FV2003 FIREAND THE BUILT Assignment Part One common thing about builders, developers and commercial property owners is their dread of a devastating fire. Indeed, it is very simple for a fire to start. All that is needed is a 'heat source or spark, some flammable material, and a few minutes of inattention for livelihoods-and lives-to go up in smoke'.1 The kitchen is where fires usually start, either in homes, hotels or restaurants. But no matter where a fire commence, it is very important to do some fire preventive measures starting from the construction of a house or a building. To start off, building construction methods and materials to be used are selected wisely and sensibly. Let us imagine that we are to design an...

### Physics

...INTRODUCTION TO PHYSICS The word "physics" is derived from "physis" which means natural development. However physics is the science that studies therelation between matter and energy, thereby gives an integrated outlook to physical phenomena. Even as early as 16th century, the concept of physics inspired many great scientists like Galileo, Newton. But it gained an independent identity in 19th century. New discoveries constantly open new outlook for learning about nature. It is a way of looking at nature from the ground up, and has inspired the philosophies of the twentieth century. Today, the scope of physics is expanding through...

...Physics (PART A) Question A particle moves with uniform speed v = 2.0 m s along a circular path of radius 5.0 m. Figure shows two points A and B on the circle. The angle subtended by the arc AB at the centre O is π/3 radians. Also shown are the velocity vectors of the particle, vA and vB, when it passes through A and B, respectively. (a) Determine the length of arc from A to B and the time Δt taken for the particle to travel along this arc. (2 marks) length of arc (S) = r · θ = 5.0 * (π / 3) = 5π/3 m. ≈ 5.24 m.
