What are the six circle theorems?
Space and AstronomySome of the important properties of the circle are as follows: The circles are said to be congruent if they have equal radii. The diameter of a circle is the longest chord of a circle. Equal chords of a circle subtend equal angles at the centre. The radius drawn perpendicular to the chord bisects the
What type of triangle is 180 degrees?
Space and AstronomyAngles of a Triangle A straight angle is just a straight line, which is where it gets its name. We’ve placed three points on it to represent the three angles of a triangle. The straight angle ABC is a 180-degree angle. Is 180 degrees a right triangle? The right triangle has one 90 degree angle
Are Hubble telescope pictures color enhanced?
Space and AstronomyThe Hubble Space Telescope only takes photos in black and white. To make those beautiful space photos you’ve probably seen, scientists add the color later, using a technique developed around the turn of the 20th century that imitates how our eyes naturally perceive color. Are the images from the Hubble telescope color enhanced? Though even
Is the Oort Cloud Real?
Space and AstronomyThe Oort Cloud is a spherical layer of icy objects surrounding our Sun, a star, and likely occupies space at a distance between about 2,000 and 100,000 astronomical units (AU) from the Sun. Has the Oort Cloud been proven? In 1950, the concept was resurrected by Jan Oort, who independently hypothesized its existence to explain
What is the theme of the rising of the moon?
Space and AstronomyThe main theme of the rising of the moon is the identity of colonialism. The theme also shows loyalty and betrayal where the police have been given difficult decisions whether to be loyal to England or to be an Irish republic. What is the plot of The Rising of the Moon? The play The Rising
Is optical rotation a physical property?
Space and AstronomySpecific rotation is a physical property like the boiling point of a sample and can be looked up in reference texts. Take a look at a problem. Enantiomers will rotate the plane of polarisation in exactly equal amounts (same magnitude) but in opposite directions. Is optical activity a chemical property? Generally, enantiomers have identical physical
How do you find pi with random numbers?
Space and AstronomyCircle and Square represent the area of the shapes. That is, we get pi by taking the number of points inside the circle divided by the number of points inside the square and multiplying by 4. How do you estimate pi with random numbers? estimate pi using random numbers make a unit circle enclosed within
What is a rhumb line sailing?
Space and AstronomyA Rhumb Line (also known as a loxodrome) is a line on the earth’s surface that crosses all meridians at the same angle. It is used as the standard method of plotting a ship’s course on a chart. This constant course or line of bearing appears as a straight line on a Mercator projection chart.
How do you find the slope of a horizontal line?
Space and AstronomyHorizontal lines have a slope of 0. Thus, in the slope-intercept equation y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept. What is the slope of a horizontal line? When two points have the same y-value, it means they lie on a
How is levenshtein distance calculated?
Space and AstronomyThe Levenshtein distance is usually calculated by preparing a matrix of size (M+1)x(N+1) —where M and N are the lengths of the 2 words—and looping through said matrix using 2 for loops, performing some calculations within each iteration. How does Levenshtein distance work? How Does the Levenshtein Distance Work? The Levenshtein distance is a similarity
