Why are metals conductive and polymers not conductive? Why are metals better conductors than polymers? These electrons are known as delocalised and so are ‘free to move’ across the surface of the metal. These free movement of electrons allows electricity to pass across a metal. In polymers, no such situation arrises and so electricity cannot […]

What is km in Lineweaver-Burk plot? The y-intercept of the Lineweaver- Burk plot is the reciprocal of maximum velocity. KM: Michaelis-Menten constant or enzyme affinity. The lower the KM the higher the affinity. Graphically the x-intercept of the line is -1/KM. Kcat: turnover number, or reactions per unit time. What happens when there is a […]

What is a monomer What is a polymer? All monomers have the capacity to form chemical bonds to at least two other monomer molecules. monomers. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units. How do monomers form polymers? […]

Why does my dog keep looking back at me when walking? Possible reasons why your dog looks back at you when you walk are that it wants to make sure you’re still with it, it’s looking to you for direction, to see that you’re ok or it might want to go faster. There are actually […]

How do you calculate the mechanical load of a motor? In our example input electrical power of the motor is 0.22 A x 6 V = 1.32 W, output mechanical power is 1000 rpm x 2 x 3.14 x 0.00126 N•m /60 = 0.132 W. Motor torque changes with the speed. At no load you […]

What is the best definition of automation? What is the best definition of automation? The use of robotic equipment in a manufacturing process. The application of scientific knowledge to find answers and fix problems. The use of resources to manufacture goods more efficiently. the hiring of workers from all over the world to manufacture goods. […]

Does it say EA Sports to the game? Originally Answered: In the FIFA game opening does it say “EA Sports”: “To the game” or “It’s in the game”? It’s in the game. It’s part of EA Sports’s motto: “If it’s in the game, It’s in the game.” Is EA the worst gaming company? In early […]

How is math used in origami? There are many aspects to the mathematics of origami, or paper folding. One may study combinatorial properties that emerge from folded paper. One can study origami as mappings from the Euclidean plane into three-dimensional space that have certain properties. Then we unfold the paper and make another crease line. […]

What are the disadvantages of air-cooled engines? What are the disadvantages of an air-cooled engine? Air-cooled engines are more likely to overheat. They can also be more expensive to build and the large fans used to cool the engine can take away a lot of power. How are aircraft engines cooled? Reciprocating engines are cooled […]
