This lab primarily aims at investigating Newton’s laws of motion. It involves the experiment on mass, velocity, time, and the acceleration of a cart. The experimental values of acceleration are compared with those of the theoretical ones. Theory The lab involves experimenting with a cart that is self-propelled using a fan. Other...

a) A thermometer is a temperature measuring device and even though there are various types such as the mercury and alcohol they all have the same basic features. A liquid-in-glass thermometer is made up of a bulb, capillary, scale, and an expansion chamber. The scale of...

-totalitarianism, holocaust, holodomor, atom bomb, allied or axis powers, Manhattan project, zyclon B Materials: http://www.radiolab.org/story/180132-how-do-you-solve-problem-fritz-haber/ Aim/Objective/Teaching Point: -To determine the extent in which technological advances changed the course of WWII. Motivation: -Showing students the visual aids or images of what took place in both...

Hooke’s law refers to a physics principle which states that “the extension of a spring is in direct proportion with the load (force) applied to it.” The law is used to approximate the elasticity of a string or response of elastic bodies. Hooke’s experiment also illustrates the relationship between the...

The purpose of this experiment was to investigate the spring constants of springs in parallel and series configurations. First, the spring constant for a single spring was investigated then spring constants for springs in parallel and series arrangements was also investigated and analyzed. The experiment was based on the Hooke’s...

The following paper aims at describing the pathophysiology of Addison’s disease (ADD) which occurs due to insufficient production of steroid hormones. The paper will utilise an article titled “Autoimmune Addison’s disease- An update on pathogenesis” authored by Hellesen, Bratland, and Husebye (2018). The title is based on the pathogenesis of...

Cooling fans are supposed to bring fresh air into the room. They are designed to rotate using a motor. However, this fan uses electricity to function. Cooling fans can be more useful if they are used to light our rooms by converting the mechanical energy produced by the motor to...

Hollywood is notorious for movies that stretch the laws of physics for the sake entertainment and commercial purposes. To illustrate how these laws are defied, for example in the fictional film The Matrix several scenes defied these laws especially the first law of Newton s motion. This is a science...

Hooke’s Law explains the behaviour of the spring and other linearly elastic objects. According to the Hooke’s Law, the stress is always directly proportional to the strain. The aim of the Hooke’s Law experiment was to investigate and verify Hooke’s Law and the acceleration due to gravity with a linearly...

Geometry is important in engineering science and mathematics. In order for students with prospects in such fields to have a better understanding of their career content, a solid background is needed in mathematical modules and units such as geometry. In this subject,...

Several researchers, scientists, as well as the engineers are expressing inner interest concerning changes of the entire earth climate. Fossils gases are being continuously utilized for the manufacture of electricity. Gases such as carbon dioxide, nitrous oxides, and methane that are produced through the burning of these fuels may lead...

When a circuit is closed, the potential difference causes charges to move within the circuit thus constituting current passing through various appliances to perform designated functions. The electrical power generated from the power source is not all utilized as desired as some of the power is lost in the form...
