What does NASA say before takeoff?
Space and AstronomyWhat does NASA say before lift off? The term ‘T-minus‘ is generally used during countdowns to space launches. During a NASA countdown to a rocket launch, ‘T-minus’ translates to ‘Time minus’; the ‘T’ stands for the exact time at which the rocket is scheduled to be launched. What does NASA say before lift off? NASA’s
How do you find the distance between two parallel lines in 3d?
Space and AstronomyFinding the (shortest) distance between two parallel lines is the same as finding the distance between a line and point. Let the line l going through the point P with position vector p in the direction of u have equation r=p+λu . How do you find the distance between parallel lines in 3D? Video quote:
What is a constant term in algebra?
Space and AstronomyIn mathematics, a constant term is a term in an algebraic expression that does not contain any variables and therefore is constant. For example, in the quadratic polynomial. the 3 is a constant term. After like terms are combined, an algebraic expression will have at most one constant term. What is a constant term example?
How do you solve Arccos?
Space and AstronomyTry this Drag any vertex of the triangle and see how the angle C is calculated using the arccos() function. Means: The angle whose cosine is 0.866 is 30 degrees. Use arccos when you know the cosine of an angle and want to know the actual angle.…For y = arccos x : Range 0 ≤
Who discovered orbits of planets?
Space and AstronomyKeplerKepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Who discovered planets first? The discovery of Uranus is credited to an astronomer called William Herschel. He was looking for comets in his back garden
What is a midline in geometry?
Space and AstronomyIn a triangle, a midline (or a midsegment) is any of the three lines joining the midpoints of any pair of the sides of the triangle. In a triangle, the midline joining the midpoints of two sides is parallel to the third side and half as long. What is a midline of a triangle? Each
How do you graph CSC?
Space and AstronomyDrawing the cosecant curve by using the sine as a guide. The cosecant goes down to the top of the sine curve and up to the bottom of the sine curve. After using the asymptotes and reciprocal as guides to sketch the cosecant curve, you can erase those extra lines, leaving just y = csc
Who hypothesized the existence of dark stars?
Space and AstronomyDark star theory history During 1783 geologist John Michell wrote a letter to Henry Cavendish outlining the expected properties of dark stars, published by The Royal Society in their 1784 volume. Who was the first person to theorize the black hole? A black hole is a volume of space where gravity is so strong that
How is the side splitter Theorem the same as the triangle Midsegment Theorem?
Space and AstronomyWhat is the difference between the triangle Midsegment theorem and the triangle side splitter Theorem? Video quote: Where you have the midpoints that are being connected. Then. The situation is that the the segment is half the size of the parallel side so in other words if I double the mid segment. Are side splitter
What is the unit of Parsec?
Space and AstronomyWhich is the unit of parsec? parsec, unit for expressing distances to stars and galaxies, used by professional astronomers. It represents the distance at which the radius of Earth’s orbit subtends an angle of one second of arc. Is a parsec a unit of time? Unfortunately, like the similarly misused ‘light-year’, the parsec is a
