What are the properties of solid figures?
Space and AstronomyProperties of Solid Shapes: Solid figures are basically three-dimensional objects, which means that they have length, height and width. Because solid figures have three dimensions, they have depth and take up space in our universe. What is solid figure? A figure that has three dimensions: length, width and height. What are the properties of plane
What is the area of an arc?
Space and AstronomySo, if l is the length of the arc, r is the radius of the circle and θ is the angle subtended at the centre, then; θ = l/r, where θ is in radians. When the angle of the sector is 2π, then the area of the sector (whole sector) is πr2. When the angle
How do you prove that a rectangle is a parallelogram?
Space and AstronomyEach pair of co-interior angles are supplementary, because two right angles add to a straight angle, so the opposite sides of a rectangle are parallel. This means that a rectangle is a parallelogram, so: Its opposite sides are equal and parallel. Its diagonals bisect each other. How do you prove that it is a parallelogram?
What is Secant over tangent?
Space and AstronomyExplanation: Use tanx=sinxcosx. And secx=1cosx. So, secxtanx=1cosx⋅cosxsinx=1sinx=cscx. What is Secx by TANX? Hence, the integration of sec x tan x is mathematically, written as ∫sec x tan x dx = sec x + C. Integral of sec x tan x is nothing but its anti-derivative only. What is SEC Times tan? tanxsecx. =(tanx)(cosx) =(sinx)(cosx)cosx. =sinx.
What is the union of two opposite rays?
Space and AstronomyAn angle is the union of two rays with a common endpoint. The common endpoint of the rays is called the vertex of the angle, and the rays themselves are called the sides of the angle. Is the union of two opposite rays a line? Answer. A pair ofopposite rays are two rays that have
How many faces does a cylinder have?
Space and Astronomy2 faces2 faces and 1 curved surface. Do cylinders have 2 or 3 faces? A cylinder has 3 faces – 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It
What do Saturn’s rings really look like?
Space and AstronomyThe ring particles mostly range from tiny, dust-sized icy grains to chunks as big as a house. A few particles are as large as mountains. The rings would look mostly white if you looked at them from the cloud tops of Saturn, and interestingly, each ring orbits at a different speed around the planet. Can
How many light hours away is Pluto?
Space and Astronomy5 1/2 hours Object Time for the Light to Reach Us Jupiter 35 to 52 minutes Pluto 5 1/2 hours (on average) Alpha Centauri (nearest star system) 4.3 years Sirius (brightest star in our sky) 9 years How far is Pluto in light hours? It took 10 years to reach Pluto, and Pluto is currently
What are the 4 operations of sets?
Space and AstronomyThere are four main set operations which include set union, set intersection, set complement, and set difference. What are the 5 operations of sets? Set Operations include Set Union, Set Intersection, Set Difference, Complement of Set, and Cartesian Product. What are the types of set operations? Set Operations Union of sets (∪) Intersection of sets
How far up is space?
Space and AstronomyThe Kármán line, an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping. The framework for international space law was established by the Outer Space Treaty, which entered into force on 10 October 1967. How far up does
