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 […]
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 are 4 ways to reduce friction?
What are 4 ways to reduce friction? Methods for decreasing friction: Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction. Lubrication is another way to make a surface smoother. Make the object more streamlined. Reduce the forces acting on the surfaces. Reduce the contact between the surfaces. Which has greatest […]
Do transistors amplify voltage?
Do transistors amplify voltage? A transistor can amplify current and it can amplify voltage and it can do BOTH at the same time. A transistor can also amplify the voltage is “sees” on the base. It does this in common-emitter mode where the emitter is connected to the 0v rail and the collector has a […]
What are the 2 main characters used for matching the pattern?
What are the 2 main characters used for matching the pattern? In SQL, the LIKE keyword is used to search for patterns. Pattern matching employs wildcard characters to match different combinations of characters. The LIKE keyword indicates that the following character string is a matching pattern. Is used for pattern matching? Generally, the REGEXP_LIKE(column_name, ‘regex’) […]
Which best describes the protection efforts for coral reefs?
Which best describes the protection efforts for coral reefs? Answer. Answer: Minimize use of fertilizers. Can the coral reefs be saved? Active and targeted restoration by creating new ways to outplants many corals at once and other interventions will reduce the decline of coral populations and support coral reef ecosystems in changing environmental conditions. Monitoring, […]
Is a sinkhole a natural hazard?
Is a sinkhole a natural hazard? Sinkholes can form on both land masses and ocean ground surfaces. They can have both, natural and anthropogenic (human made) causes. Most natural sink holes are often caused by erosion which can either be physical or chemical. Human made sink holes are often a result of underground development such […]
Why do blue objects look blue?
Why do blue objects look blue? Objects that appear blue do so because they reflect blue light but absorb all other colors, so our eyes only see the blue light remaining. When a blue object absorbs the energy from non-blue light, it heats up. What Colour does a blue object appear in blue light? A […]
Can you kill a fly by slapping it?
What is acceleration at the highest point?
What is acceleration at the highest point? At a projectile’s highest point, its acceleration is zero. What is acceleration at maximum height? The acceleration is always −9.8m/s as long as the ball is in the air, and the velocity at the top is zero. Why is acceleration at 0 highest? Answer: 0 m/s. The instantaneous […]
