What is first angle projection method?
Space and AstronomyFirst angle projection is one of the methods used for orthographic projection drawings and is approved internationally except the United States. In this projection method, the object is placed in the first quadrant and is positioned in front of the vertical plane and above the horizontal plane. What is the first angle of projection? In

What are the 5 properties of real numbers?
Space and AstronomyDid you know there were so many kinds of properties for real numbers? You should now be familiar with closure, commutative, associative, distributive, identity, and inverse properties. What are the 5 properties in math? Commutative Property, Associative Property, Distributive Property, Identity Property of Multiplication, And Identity Property of Addition. What are the 5 different types

What does DF mean in maths?
Space and AstronomyThe differential of a function f(x) of a single real variable x is the function df of two independent real variables x and Δx given by. One or both of the arguments may be suppressed, i.e., one may see df(x) or simply df. If y = f(x), the differential may also be written as dy.

What is the orbital path of the sun?
Space and AstronomyEarth orbits the Sun in a slightly flattened circle called an “ellipse.” In geometry, the ellipse is a curve that loops around two points called “foci.” The distance from the center to the longest ends of the ellipse is called the “semi-major axis,” while the distance to the flattened “sides” of the ellipse is called

When did Galileo publish his findings?
Space and AstronomyBy the end of 1609 Galileo had turned his telescope on the night sky and began to make remarkable discoveries which he described in a short book called the Starry Messenger, published in Venice in May 1610. When did Galileo publish his theory? Galileo continued his study of astronomy and became more and more convinced

How many types of elliptical galaxy are there?
Space and AstronomyIt is sometimes said that there are two physical types of ellipticals: the giant ellipticals with slightly “boxy”-shaped isophotes, whose shapes result from random motion which is greater in some directions than in others (anisotropic random motion); and the “disky” normal and dwarf ellipticals, which contain disks. Are there any elliptical galaxies? M87, identified as

How does a water rocket work?
Space and AstronomyThe way a water rocket works is by filling it up partially with water and then pressurizing the inside with air. When the bottom nozzle is opened the internal air pressure forces the water out of this nozzle at high speed causing the rocket to shoot straight up at high speed. How does a water

What does continuity mean in math?
Space and Astronomycontinuity, in mathematics, rigorous formulation of the intuitive concept of a function that varies with no abrupt breaks or jumps. A function is a relationship in which every value of an independent variable—say x—is associated with a value of a dependent variable—say y. What does continuity mean in calculus? A function is said to be

What did Penzias and Wilson win the Nobel Prize for?
Space and Astronomyof cosmic microwave background radiationtheir discovery of cosmic microwave background radiation.” What did Penzias and Wilson discover? This cosmic radiation initially appeared to become weaker as wavelengths of the radiation became shorter. However, when Arno Penzias and Robert Wilson studied cosmic radiation in 1964, they discovered that microwaves with a wavelength of about 7 centimeters
