What is the length of arc AB?
Space and Astronomy10π5/18 of the circumference of the circle, which equals 2πr, according to the formula for circumference. length of arc AB = (5/18)(2πr) = (5/18)(2π(18)) = 10π. Thus, the length of arc AB is 10π. How do you find the length of arc AB? How do you calculate arc length without the angle? Divide the chord
What is C in concave mirror?
Space and AstronomyThe centre of curvature (C) is the centre of the circle (sphere) of which the mirror is an arc. What is C and F in concave mirror? Properties of image: Positions of Object and Image in Concave Mirror Position of Object Position of Image Size of Image Between C and F Beyond C Enlarged At
What happens in the accretion disk?
Space and Astronomyaccretion disk, a disklike flow of gas, plasma, dust, or particles around any astronomical object in which the material orbiting in the gravitational field of the object loses energy and angular momentum as it slowly spirals inward. What happens when accretion occurs? In planetary science, accretion is the process in which solids agglomerate to form
What planet can we live on?
Space and AstronomyAmong the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability. What planets can humans live on? Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation
What is plane of projection in engineering drawing?
Space and AstronomyDefinition of plane of projection : a plane that is intersected by imaginary lines drawn from the eye to every point on the object and that is therefore the plane on which the pictorial representation in perspective is formed. What are the 3 planes of projection? Figure 5-4 shows the three principal (or primary) planes
Does a rectangle have 4 sides of equal length?
Space and AstronomyWhat is a rectangle? A rectangle is a quadrilateral with 4 right angles. A shape with four sides of equal length. The shape has two sets of parallel sides and has four right angles. Does a rectangle have all sides the same length? Definition: A rectangle is a quadrilateral with all four angles right angles.
Which type of telescope is more expensive?
Space and AstronomyWhich type of telescope is more expensive? With limited funds, which type of telescope would be your choice? A reflector, because it is less expensive than the same size refractor, and can be made larger than a refractor. What is the most expensive type of telescope? The James Webb Space Telescope (JWST) is the most
What is annular area?
Space and AstronomyAn annulus or the annular region can basically be defined as a shape that is made out of two circles. It is a plane figure that is formed by two concentric circles. The region covered between two concentric circles is known to be the annulus or the annular region. How do you find annular area?
How long does it take for the Space Needle to rotate?
Space and AstronomyThe Loupe is made of 37 tons of glass and powered by 12 motors, which can adjust in speed. The floor can make a full rotation in 20 minutes at its fastest, but when the Loupe opens to visitors, the floor will be moving at 45 minutes per full rotation. How often does the Space
What is the sign of the leading coefficient of F?
Space and AstronomyThe limiting behavior of a function describes what happens to the function as x → ±∞. The degree of a polynomial and the sign of its leading coefficient dictates its limiting behavior.…Polynomial Functions. Degree of the polynomial Leading coefficient + – Even f(x) → ∞ as x → ±∞ f(x) → -∞ as x →
