Abstract The interesting rheological behaviour of the Casson magnetohydrodynamic fluid has sparked the recent emergence of various hypotheses. While the connection between shear stress and shear rate in Newtonian fluids is linear, it is nonlinear in Casson fluids. Some well-known examples of Casson fluid are “jelly, tomato sauce, honey, soup, concentrated fruit liquids, and even human blood”. Casson MHD fluids exhibit higher viscosity compared to Newtonian fluids, allowing for better

Newton in his masterpiece Principia explained the reason why planets revolving in orbits are not circles in their structures but ellipses for which he developed three important “laws of motion”. These “three laws of classical mechanics” have revolutionized the physical world as they describe the motion of a body or an object and its relationship with the force that acts on a certain object. This paper explores these three laws

Introduction The word comet is derived from cometa. The outer space is filled with a great number of surprises and mysteries. The comets are also one of the great mysteries. Uncountable comets are rotating around the sun and are part of the solar system. The most successful comet discovery of all time is of Jean-Louis Pons. He claims that he had discovered almost thirty-seven comets. The second most high-volume was

Cohesiveness means a tendency of a given group to come together and agree to be united, at the same time working towards their objectives or to satisfy their emotional needs. The togetherness of a group might be caused by internal factors such as group pride, threats from other groups, influence, and the intensity of the individual’s interaction. Cohesiveness in a group plays a very important role; first, cohesiveness reflects the

Introduction The main aim of this experiment is to compare the difference in sound inputs. Sound is to be input to a speaker, and the sound produced by the speaker is detected by a microphone. The sounds injected into the speaker and those detected by the microphone are to be compared. An oscilloscope is to be used to measure the levels of the two and compare them. A tube is

Introduction This laboratory investigates direct-current series and parallel circuits using theoretical calculations and the PhET Circuit Construction Kit. The purpose is to apply Ohm’s law, equivalent-resistance rules, Kirchhoff’s laws, and electrical-power equations, then compare calculated values with simulated measurements. Four resistor networks are examined: two series circuits and two parallel circuits. A simulation is valuable because it allows voltage and current to be measured without the component tolerances, wire resistance,

Q1: (60 marks) A piston-cylinder device initially contains air at 200 kPa and 127 0C. At this stage, the piston rests on a pair of stops, as shown in the figure below, and the enclosed volume is 200 liters. The mass of the cylinder is such that a 300 kPa inside pressure is required to move it. The air is now heated until its volume has doubled. Determine (a) the

Radiation is the transmission or emission of energy from a source through the movement of particles or waves. This energy may travel through a material medium or through empty space. Radiation is present everywhere in the environment, and human beings are exposed to it every day from both natural and human-made sources. Although the word radiation often creates fear, not all radiation is harmful. Some forms of radiation are part

In numerous ways, Burke’s thesis is more related to the grade principles theory of chaos in quantum physics. (Burke, 1966; Lorenz, 1963) The reason how we are able to understand, interpret and explain what we want to define and measure directly changes what we intend to define and measure. This is time and again referred to as the ‘Uncertainty Principle’ attributed to the German physicist Weiner Heisenberg. (Heisenberg, 1927/1983) In

Introduction Classical mechanics is the framework used to describe the motion of macroscopic bodies when speeds are much lower than the speed of light and quantum effects are negligible. It is often called Newtonian mechanics, but it was not created by Isaac Newton alone. Its development depended on ancient debates about motion, medieval mathematical work, Renaissance astronomy, Galileo’s experiments and idealizations, Kepler’s planetary laws, Descartes’ and Huygens’ studies of impact,

Balancing a ruler appears simple, but the explanation depends on the orientation of the ruler and on what “balancing faster” means. A ruler resting horizontally on a finger is a problem of static equilibrium: it remains level when the support is directly below its center of mass, so the net torque about the finger is zero. A ruler held upright on a fingertip is a different problem of dynamic stability:

Introduction This laboratory exercise compares a ruler, outside micrometer, vernier caliper, and digital measuring instrument. The original report correctly recognizes that instruments differ in resolution and that parallax can affect ruler readings. It also records several sample measurements. However, it confuses resolution with accuracy, treats the vernier scale as a percentage-error scale, gives results without consistent units, and states that digital instruments are automatically 99% accurate.

CHAPTER 4 ANALYSIS AND DISCUSSION 4.1 Component Design The micrometer is a precise measuring instrument, mostly used by engineers each part of the micrometer was designed with the ideas and variables that were set forth at concept design.  The interchangeable micrometer was developed in order to reach the goal of improving the older models of micrometers in order to make it more efficient and affordable.  The dimensions of the tools
