What is heat of the sun?
Space and AstronomyThe temperature of the sun varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) at the core to only about 10,000 degrees F (5,500 degrees C) at the surface, according to NASA. What’s the heat of the sun? The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The
What is long radius and short radius elbow?
Space and AstronomyThe long radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to 1.5 times, that is, R = 1.5D. A short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = D. What is a short elbow? Long
How did Wally Schirra die?
Space and Astronomynatural causesnatural causes. Why did Wally Schirra leave NASA? Schirra, a 45-year-old former Gemini astronaut and a Navy test pilot, was at the center of the disputes. He had already decided to leave NASA when he was selected for the Apollo 7 mission. “He had very little at stake,” Muir-Harmony says. “That might have something
Can you spray paint brake pads?
Space and AstronomySome people use spray-on paint rather than brush-on paint. That can work too, but make sure it’s paint designed to endure high temperatures, such as engine block paint. Don’t use normal spray paint, which will flake off. You may also want to buy a can of clear, high-temperature finishing spray. Is it OK to paint
What are the stages of a rocket going into space?
Space and AstronomyThe first stage is ignited at launch and burns through the powered ascent until its propellants are exhausted. The first stage engine is then extinguished, the second stage separates from the first stage, and the second stage engine is ignited. The payload is carried atop the second stage into orbit. What are the 3 stages
How are eyebrow windows measured?
Space and AstronomySimple measure the width across the bottom and the height in the center. Arch rests directly on sill. Note: Factory adds about 1” offset around sides and top of arch to allow arch to overlap the window opening. For example: window width=34”, actual arch width=36”. How do you measure your eyebrow arch? Video quote: Hold
How do you keep calla lilies alive in a vase?
Space and AstronomyEvery day, add fresh water to the vase to keep the calla lilies hydrated and to reduce the growth of bacteria. If you see the stems start to split or if they become slick due to bacteria buildup, recut them under water to keep them healthy. How long do calla lilies last in a vase?
What does HL theorem mean?
Space and AstronomyWhat is the HL Postulate? The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent. What is an example of HL Theorem? Video quote: So consider the two triangles let's call the first one
What did WMAP reveal about the universe?
Space and AstronomyWMAP determined the age of the universe to be 13.8 billion years. WMAP also measured the composition of the early, dense universe, showing that it started at 63 percent dark matter, 12 percent atoms, 15 percent photons, and 10 percent neutrinos. What does the WMAP data show? WMAP measures anisotropy* with much finer detail and
Do caliper covers reduce brake dust?
Space and AstronomyThey help keep brakes clean – Caliper covers redirect the dust that comes off of your brake pads toward the rear of the vehicle, meaning less dust flies onto the outside surface of your wheels. What is the purpose of caliper covers? The caliper covers redirect the dust that comes off your brake pads toward
