structure causes the proteins themselves to be different; due to the original different primary structure the haemoglobin protein is soluble in water whereas the collagen protein is not. Secondary structure; Formed when the chain of amino acid coils or folds to form an alpha helix or beta pleated sheet. Haemoglobin is comprised of four polypeptide subunits‚ two with alpha helix secondary structure and two with beta pleated sheet form. All four components carry a heme group that

Diesel engines and unleaded fuel engines better known as gasoline engines are actually very similar. They are both internal combustion engines which is to convert the chemical energy in fuel into mechanical energy. This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft‚ and the up-and-down motion of the pistons‚ known as linear motion‚ creates a force to the flywheel the from the flywheel to the transmission. The working principle of diesel engines

Circular motion‚ gravitational field‚ and oscillation 1.Define gravitational field strength: Force per unit mass 2. Explain why there is a point between two point masses at which the gravitational field strength is zero. Because gravitational fields of two masses are in opposite directions‚ so there is a point where it is zero What is meant by angular velocity The rate of change of the angular displacement of an object as it moves along curved path. Generally when asked to test

Procedure: 1. The compass was placed on the lab table with no magnets nearby to identify what direction was north relative to the classroom. 2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular

101 BASICS SERIES LEARNING MODULE 19: STARTERS AND CONTACTORS Cutler-Hammer STARTERS WELCOME Welcome to Module 19‚ which is about starters‚ devices that control the use of electrical power to equipment‚ usually a motor. As the name implies‚ starters “start” motors. They can also stop them‚ reverse them‚ accelerate them‚ and protect them. Starters are made from two building blocks‚ contactors and overload protection: • Contactors control the electric current to the motor. Their function is

current from a wall outlet) is placed into a primary coil which is capacitively loaded‚ the coil will ’ring’‚ and form an oscillating magnetic field. The energy will transfer back and forth between the magnetic field in the inductor and the electric field across the capacitor at the resonant frequency. This oscillation will die away at a rate determined by the Q factor‚ mainly due to resistive and radiative losses. However‚ provided the secondary coil cuts enough of the field that it absorbs more energy

rarely used for logic. A relay is a simple device that uses a magnetic field to control a switch‚ as pictured in . When a voltage is applied to the input coil‚ the resulting current creates a magnetic field. The magnetic field pulls a metal switch (or reed) towards it and the contacts touch‚ closing the switch. The contact that closes when the coil is energized is called normally open. The normally closed contacts touch

Jamie Oliver Jamie Oliver is a chef who has made a number of television programmes for Channel 4; in most of these programmes he is cooking and instructing the audience‚ although he is sometimes part of documentaries about food‚ for example in schools. His style of speech is very different to many of his contemporaries: he uses his distinctive style to present himself as a down to earth‚ friendly TV chef. Oliver is the only person talking in this transcript because he is cooking and explaining
