Which of the following is transition curve?
Which of the following is transition curve? Explanation: A clothoid is an ideal transition curve in which, length is inversely proportional to the radius of the curve. It is also known as Glover’s spiral. Explanation: Cubic parabola is also known as Froude’s transition curve. Which is best for Valley curve? For gradually introducing and increasing […]
Why do s block elements not act as catalysts?
Why do s block elements not act as catalysts? State how a catalyst speeds up a chemical reaction. Suggest why ions from s block elements do not usually act as catalysts. Because only exist in one oxidation state. Give one reason why, in the absence of a catalyst, the activation energy for the reaction between […]
Will a magnet stick to real silver?
Will a magnet stick to real silver? “Silver is not noticeably magnetic, and exhibits only weak magnetic effects unlike iron, nickel, cobalt, and the like,” says Martin. “If your magnet sticks strongly to the piece, it has a ferromagnetic core and is not silver.” Fake silver or silver-plated items are generally made of other metals. […]

What happens to the carbon and oxygen from CO2 after it has been removed from the air by the plant? Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. The carbon dioxide enters the leaves of the plant through small pores called stomata. Once the process is […]
What is static and dynamic multiplier?
What is static and dynamic multiplier? As the name suggests, static multiplier is based on assumptions, while dynamic multiplier considers all the economic variables as realistic, and therefore movable and changeable. What is a static multiplier? The concept of static multiplier implies that changes in investment causes change in income instantaneously. It means that there […]
What is one of the benefits of using a higher kVp?
What is one of the benefits of using a higher kVp? One advantage of using high kV technique is shorter exposure time [1]. The higher the energy, the more photons will penetrate the body, the less that are absorbed. Although this reduces patient dose, image quality is compromised due to reduced contrast of a preferentially […]
