What is the length of line segment AC?
Space and AstronomyThe length of line segment AC in the Triangle ABC is 14. What is the length of AC? Find the length of AC. c2 = a2 + b2 142 = 32 + b2 196 = 9+ b2 b2 = 196 − 9 = 187 b = √187 = 13.67 (2dp.) The length of AC is
Which mirror is used in solar furnace?
Space and Astronomyconcave mirrorconcave mirror is used in the design of solar furnaces because they converge the parallel sun rays at a point. This helps to increase the temperature of the furnace. Which mirror is used in the solar furnace and why? concave mirror The solar furnace is kept practically at the focal point of the broad
Does Gator Grip work on rounded bolts?
Space and AstronomyGator Grip did the job on the bolt… worn down and all. The secret is the 30 retractable steel pins inside. “You push the little pins in, and when you push it in, whatever’s rounded, the pins fall into place,” Florey says. Does Gator Grip socket work on stripped bolts? Although they work ok for
What are non coplanar points in geometry?
Space and AstronomyNon-coplanar points: A group of points that don’t all lie in the same plane are non-coplanar. In the above figure, points P, Q, X, and Y are non-coplanar. The top of the box contains Q, X, and Y, and the left side contains P, Q, and X, but no flat surface contains all four points.
What was the first successful mission to Mars?
Space and AstronomyMariner 4First success and more attempts,1964 – 1971 NASA’s Mariner 4 was the first craft to finally reach Mars. The spacecraft launched on Nov. 28, 1964, and was the first to fly by the planet on July 14, 1965. It sent 21 photos of its target back to Earth. What was the first mission that
Is a simple graph connected?
Space and AstronomyA simple graph may be either connected or disconnected. Unless stated otherwise, the unqualified term “graph” usually refers to a simple graph. A simple graph with multiple edges is sometimes called a multigraph (Skiena 1990, p. 89). Does simple graph need to be connected? A simple graph doesn’t need to be connected. If a vertex
Where is most of the water on Mars?
Space and Astronomypolar ice capsfrozen deep below the surface, within polar ice caps and in permafrost. Where is the most water found on Mars? While water is known to exist on Mars, most is found in the planet’s cold polar regions as ice. Water ice is not found exposed at the surface near the equator, as temperatures
How are large distances in space measured?
Space and AstronomyBecause space is so big, many astronomers do not like to say how far away things are using miles or kilometers. Instead, we use a measurement that we call a parsec. Remember Alpha Centauri, the closest star? It is 1.347 parsecs, or 41,560,000,000,000 (or 41.56 trillion) kilometers away. What is used to measure large distances
What is a trapezoid 1st grade?
Space and AstronomyTrapezoids are an exciting and challenging new shape that your student will start to learn about around first grade. Trapezoids are defined as 4-sided flat shapes with straight sides where at least one pair of those opposite sides are parallel. What is a trapezoid simple definition? : a flat geometric figure with four sides but
How do you find the actual size of a specimen?
Space and AstronomyCalculation of Actual Size: To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification. How do you find the actual size of a specimen microscope? Estimating the Size of the Specimen Under Observation To estimate the size of an object seen with
