disadvantage is that these types of cookers are the least safe out of all the cookers. Radiant coil cookers are the most common of all the cookers. They are also the cheapest cookers to purchase initially. These types of cookers are heated by electrical resistance. These cookers are more efficient than solid disc cookers and ceramic top cookers. Solid disc cookers are similar to radiant coil cookers. They are just solid and fixed to the cooker. They do not need to be removed for cleaning. These elements have

LESSON 1: History of Electronics The introduction of vacuum tubes at the beginning of the 20th century was the starting point of the rapid growth of modern electronics. With the vacuum tubes the manipulation signals became possible, which could not be done with the early telegraph and telephone circuit or with the early transmitters using high voltage sparks to create radio waves. Example: weak radio and audio signals can be amplified, audio signals such as music or voice can be superimposed

transportation, cars are leading the way when it comes to electric use. In not so distant future, I expect cars to use more than half of their energy consumption from electricity. Right now, electric cars for propulsion, they use the energy stored in a battery. Just like anything in the world, there are many pros and cons when it comes to electric cars, for example even if electric cars produce no exhaust but they also require long

What is the difference between speed and velocity? * Speed is how fast you’re going * Velocity is how fast you’re going but you need to add direction of the way you’re going in. What are different parts of a distance-time graph? * Flat sections up – steady speed * Flat line – stopped * Curved line up – accelerating * Line curving off – decelerating * Straight line down – steady speed in other direction How do you calculate speed from a distance time graph?

become an indispensable piece of equipment in manufacturing and warehousing operations. The middle 19th century through the early 20th century saw the developments that led to today's modern forklifts. The Pennsylvania Railroad in 1906 introduced battery powered platform trucks for moving luggage at their Altoona, Pennsylvania train station. World War I saw the development of different types of material handling equipment in the United Kingdom by Ransomes, Sims and Jeffries of Ipswich. This was in
