Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

Surface Waves: Understanding its movements I. Introduction We treat here an important wave phenomenon‚ the surface wave. It occurs in many physical systems both mechanical and electromagnetic. Mechanical surface waves can exist at the interface between two media with different densities such as the oceans and air. Ordinary sea waves and tsunamis are surface waves. Seismic events can produce both longitudinal and shear waves at the earth’s surface‚ resulting in earthquakes. Electromagnetic surface

causing a catabolic reaction. Or two or more substrates are bonded to make one product causing an anabolic reaction. There are five factors that effect enzyme activity. They are: ·Temperature ·pH ·Inhibitors ·Substrate Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because

Causes and Effects of Advertising of Water Pollution in Lake Huron Luis Paredes Dr. Wallace ENG 115 Water Quality is very much in the news these days and it is also a growing public concern. Water is one of the most important resources on the planet and affects nearly every aspect of life. The Great Lakes watershed contains a large percentage of the world’s fresh surface water. The Lakes support the water needs‚ and jobs of millions of people and poor water quality is an increasing frustration

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy

Water Pollution and Its Effects on the Environment Water is probably the most important resource we as people have. Humans can survive without food for several weeks‚ but without water we would die in less than a week. On a slightly less dramatic note‚ millions of liters of water are needed every day worldwide for washing‚ irrigating crops‚ and cooling industrial processes‚ not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water‚ we use

Microsoft’s Surface Pro laptop-in-disguise1 tablet is no different‚ a “flawed”2 device which has seen improvements to its design and structure over the past few years making it slowly approach perfection. Microsoft’s Surface Pro is one of the newer innovative devices that was initially introduced in February 20133 and has seen a much shorter succession cycle than that of any other popular tablet manufacturer‚ namely Apple. Adoption rate was not at its best with the initial introduction of the Surface Pro

Arrangements of cells and atoms‚ their repeating patterns‚ the rhythms of their form forces architects to question the building components‚ just as Otto did by the inspiration of radiolarians. In a way to continue in the search of the effect of these self-generated dynamic forms‚ Hensel‚ Menges and Weinstock provides information about the methods that can be followed to apply the inspirations from biology to architecture in the intro of the book Emergent Technologies and design: Towards
