What do ripple marks tell us?
Space and AstronomyRipple marks are sedimentary structures and indicate agitation by water (current or waves) or wind. Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment. What do ripple marks indicate? In geology, ripple marks are sedimentary structures (i.e., bedforms of the lower flow regime) and indicate agitation
How many enantiomers are there?
Space and Astronomytwo pairstwo pairs of enantiomers. Any given molecule has its enantiomer; the two other molecules are its diastereomers. How do you know how many enantiomers? If ‘n’ is even (here n is the number of chiral centres): Number of enantiomers=2n−1. Number of meso compounds=2n/2−1. Total number of optical isomers=2n−1+2n/2−1. If ‘n’ is odd: Number of
What is the full meaning of galaxy?
Space and AstronomyWhat is the real meaning of galaxy? A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system. What is a galaxy in one word answer? A galaxy is a
How did Mars get its scar?
Space and AstronomyBut the initial culprits in this case were giant meteorites smacking the planet. The first meteorite, which delivered a head-on blow to Mars about 3.4 billion years ago, created a 30 km (18.6 mi) impact scar while catapulting waves hundreds of meters high across vast distances. What are Mars scars? Mars is covered in intriguing
What is the formula of tan 90 Theta?
Space and Astronomytan (90° + θ) = – cot θ. How do you find tan 90 Theta? Video quote: And tan 90 plus theta will be equal to y coordinate of this point divided by x coordinate of this point that is cos theta divided. By minus sine theta. And this will be equal to minus cot
What is view matrix?
Space and AstronomyThe View Matrix. Like the model matrix, the view matrix can contain translation and rotation components – but instead of transforming an individual object, it transforms everything! It moves your geometry from world space to view space – that is, a coordinate system with your desired viewpoint at the origin. What is a camera view
What is the use of sundial?
Space and Astronomysundial, the earliest type of timekeeping device, which indicates the time of day by the position of the shadow of some object exposed to the sun’s rays. As the day progresses, the sun moves across the sky, causing the shadow of the object to move and indicating the passage of time. Where was the sundial
What is a light year quizlet?
Space and AstronomyLight Year. A unit that equals the distance light travels through space in one year; a way to measure extremely vast distances; it equals 9.46 trillion kilometers or 9.49 x 1012 km. What is light-year short answer? A light-year is a measurement of distance and not time (as the name might imply). A light-year is
What is D sugar and L sugar?
Space and AstronomyWhat is D and L form of sugar? D-Glucose: D-Glucose is a sugar molecule that is abundant in nature. L-Glucose: L-Glucose is a sugar molecule that is less abundant in nature. What is difference between D-sugar and L-sugar? Summary – D vs L Glucose The difference between D and L glucose is that in D-glucose,
What are the four angle types formed by parallel lines cut by a transversal?
Space and AstronomyWhen parallel lines are cut by a transversal, there are 4 special types of angles that are formed – corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles. What are the four angles formed by Transversals? It intersects two lines at distinct points. Intersection caused by transversal forms several angles. These are
