Is it possible for a solid metal ball to float in mercury? Is it possible for a solid metal ball to float in mercury? No, the mass of the solid metal ball is greater than that of the mercury so it will not float. Why the ships can float on the sea but a small […]
What colors absorb light the most?
What colors absorb light the most? Obviously the black strip absorbed the most. But the red, blue, and green ones did not absorb much. Interestingly, the dark gray and purple ones absorbed absorbed more than I would imagine. What color does blue pigment subtract from white light? When blue is subtracted from white light, the […]
What are two types of chemical reactions?
What are two types of chemical reactions? Types of Chemical Reactions Synthesis reactions. Two or more reactants combine to make 1 new product. Decomposition reactions. A single reactant breaks down to form 2 or more products. Single-replacement reactions. A single element replaces a similar element of an adjacent reactant compound. Double-replacement reactions. Combustion reactions. How […]
Which line is parallel to Y 2×2?
What is the principle of Maldi-Tof?
What is the principle of Maldi-Tof? MALDI is the abbreviation for “Matrix Assisted Laser Desorption/Ionization.” The sample for MALDI is uniformly mixed in a large quantity of matrix. The matrix absorbs the ultraviolet light (nitrogen laser light, wavelength 337 nm) and converts it to heat energy. What is the role of Reflectron in Maldi-Tof? A […]
How do you find cosine 300 degrees?
How do you find cosine 300 degrees? Since cos(60∘)=12 , we know that cos(300∘)=12 as well since cos(θ)>0 in the fourth quadrant. Which of the following is equal to COS 300? Important Angle Summary θ° θradians cos(θ) 225° 5π/4 -√2/2 240° 4π/3 -1/2 270° 3π/2 0 300° 5π/3 1/2 Which of the following is equivalent […]
What is driving reaction distance?
What is driving reaction distance? Reaction distance is the distance the vehicle travels from the point a driver perceives or decides that something is a hazard, until braking. Braking Distance: Braking is what the driver does to slow a vehicle. How do you calculate reaction time and distance? We can use the distance the meter […]
What is wave size and energy influenced by?
What is wave size and energy influenced by? Waves are generated by wind blowing over the sea. The characteristics of waves are determined by the strength of the wind, its duration and fetch (distance a wave travels). The stronger the wind the greater the friction on the surface of the sea and therefore the bigger […]
How many tons of coal are in one train car?
How many tons of coal are in one train car? 120 tons What is a railroad dump? Center Dump Car. A car which will discharge its entire load between the rails. How are hopper cars unloaded? Hoppers are used to haul bulk freight such as coal, gravel, and grain; they have either several discharge hatches […]
What controls how much sediment a river can carry?
What controls how much sediment a river can carry? The two main flow factors in sediment transport are the settling rate and the boundary layer shear stress 27. What property of flowing water determines how much sediment it can carry? Sediments carried as solids as the stream flows are called a suspended load. The size […]
