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

Astronomers have made significant strides in understanding the planetary systems of other stars, known as exoplanetary systems. Currently, more than a thousand other worlds have been discovered using various techniques such as direct imaging, transit photometry, and radial velocity measurements (NASA). The exoplanets have different characteristics, such as rocky planets similar to Earth, exotic worlds, and gas giants similar to Jupiter. Moreover, through studies of planets’ formation, evolution, and dynamics

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

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 litres. 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

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

Procedure PheT Sims Play Electricity, Magnets, and Circuits Circuit Construction Kit (AC+DCy) To add elements to your circuits, simply drag an item into the work area. To remove an item or change it, right-click the item you wish to change. To uncouple two circuit elements, right-click on the circular junction and choose “split junction.” To measure voltage and current, click on the boxes to the left. Remember, voltage is read

The transmission or emission of energy from a source through the propagation of particles or waves via a medium (whether material or space) is known as radiation. This radiation may be categorized as either ionizing, with an energy of more than ten eV, or non-ionizing, with an energy of less than 10 eV. Radiation may be generated from a variety of sources, both natural and human-made. The most important natural

In numerous ways, Burke’s thesis is more related to the grade principles theory of chaos in quantum physics. 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. In the simplest form, the principle states

The term Classical Mechanics, also known as Newtonian Mechanics is one of the major fields of physics which is the collection of research done by Isaac Newton and Gottfried Wilhelm Leibniz. This term originated in the twentieth century to describe the principles of physics as described by Newton. It includes the astronomical theories presented by Johannes Kepler and projectile motion concepts as given by Galileo. However, many scientists consider the

Objectives The primary objectives of this lab are: To generate digital signals with the addition of noise To build a zero-crossing threshold detector Abstract This experiment is about generating digital signals with noise content added to them and making a digital threshold detector. Thus, this lab will help us understand the concept of noisy signals and assist in comprehending the underlying design of digital threshold detectors. This report, however, caters

From the observations after balancing the two rulers (one shorter and another one longer), it is observed that a shorter ruler balances faster than a longer ruler. This is due to the effects of the force of gravity on the rulers, plus other factors, including the effort and load distance.  Effort distance can be considered from the fulcrum or the turning point (the finger) to one end of the ruler.
