Are all solids polyhedrons?
Space and AstronomyNevertheless, there is general agreement that a polyhedron is a solid or surface that can be described by its vertices (corner points), edges (line segments connecting certain pairs of vertices), faces (two-dimensional polygons), and that it sometimes can be said to have a particular three-dimensional interior volume. Is every solid a polyhedron? The polyhedrons are
How do you remove old paint from brake calipers?
Space and AstronomyPaint stripper, or you can sand blast them, i would actually use soda blast as it is not abrasive, you just have to make sure to clean them really well after basting as it leaves a coating on the parts. How about brake fluid? It eats through paint like crazy, and calipers are immune to
Is the sky blue or white?
Space and AstronomyThe sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. What is the real color of the sky? The Short Answer: Gases and particles in Earth’s atmosphere scatter sunlight in all directions.
How much would you weigh on Jupiter compared to Earth?
Space and AstronomyAlthough Jupiter is a great deal larger in size, its surface gravity is just 2.4 times that of the surface gravity of Earth. This is because Jupiter is mostly made up of gases. If you weigh 100 pounds on Earth, you would weigh 240 pounds on Jupiter (assuming you could find someplace to, well, stand).
How do you differentiate conics?
Space and AstronomyWhat is considered the best comic book of all time? The Best Comics Of All Time Watchmen. The Sandman. Bone. Jonathan Hickman’s Marvel-verse, . Doom Patrol by Grant Morrison & Richard Case. Mister Miracle. Mind MGMT. Maus. What is the #1 comic book? According to the most recently available data, the best-selling American single-issue comic
What is convergence and divergence series?
Space and AstronomyA convergent series is a series whose partial sums tend to a specific number, also called a limit. A divergent series is a series whose partial sums, by contrast, don’t approach a limit. Divergent series typically go to ∞, go to −∞, or don’t approach one specific number. What is convergence of series means? A
What is hysteresis in image edge detection?
Space and AstronomyWhat is hysteresis in edge detection? The thresholder used in the Canny operator uses a method called “hysteresis”. Most thresholders used a single threshold limit, which means if the edge values fluctuate above and below this value the line will appear broken (commonly referred to as “streaking”). What is hysteresis in image processing? In image
What is a circumscribed shape?
Space and AstronomyA circumscribed figure is a shape drawn outside another shape. For a polygon to be inscribed inside a circle, all of its corners, also known as vertices, must touch the circle. What is circumscribed in a circle? In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the
What happens when a blue supergiant dies?
Space and AstronomyThe Death of Blue Supergiants As we mentioned above, supergiants will eventually die as supernovae. When they do, the final stage of their evolution can be as a neutron star (pulsar) or black hole. Supernova explosions also leave behind beautiful clouds of gas and dust, called supernova remnants. What do blue supergiants turn into? Blue
Why did NASA choose Florida as the location for space exploration?
Space and AstronomyFrom a fuel efficiency and expense perspective, with the amount of energy needed to launch an object, that 0.3 percent savings goes a long way. Cape Canaveral was also chosen because of how close it is to the Atlantic Ocean. Why is NASA located in Florida? Cape Canaveral is located along the East Coast of
