Where would a space elevator be built?
Space and AstronomyA space elevator on Earth or the moon could make space travel and cargo transport easier, cheaper, and more sustainable. Companies in China and Japan hope to build such elevators by , respectively. Japanese researchers have even tested miniature prototypes in space. Does a space elevator have to be on the equator? To support the
What are isomorphous substances?
Space and Astronomy(of a compound or mineral) capable of crystallizing in a form similar to that of another compound or mineral, used especially of substances so closely related that they form end members of a series of solid solutions. What are isomorphous crystals give example? Two crystals are said to be isomorphous if (a) both have the
What is the difference between total and annular eclipse?
Space and AstronomySolar eclipses may be classified as either total, in which the Moon completely covers the Sun, or annular, in which the Moon obscures all but an outer ring of the Sun. Whether an eclipse is total or annular depends on the distance between these three objects. What is the difference between a total solar eclipse
What does Hester do with the extra money she earns?
Space and AstronomyShe gives away all her spare money to the poor, on people who actually have more than she does. She also makes garments for the poor, and her charity is perhaps a form of penance for her sins. Besides using the money she earns as a seamstress to support herself and Pearl, Hester also uses
What causes a caliper to lock up?
Space and AstronomyEven though you may not have pressed on the brakes, residual hydraulic pressure can cause the brake calipers to activate and lock. This is the most common form of lock-up on the road today. Don’t ignore this problem as it can quickly lead to mechanical failure of other parts of your braking system. What causes
Are two vertical angles complementary?
Space and AstronomyVertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary. Is vertical angles supplementary or complementary? Lesson Summary You learned that complementary angles are two angles that add up to 90 degrees, supplementary angles are two angles that add up to 180 degrees, vertical angles are opposite angles at an
What is the cast rule?
Space and AstronomyThe CAST Rule. The CAST Rule says that in quadrant I all three of sinθ, cosθ, tanθ are positive. In quadrant II, only sinθ is positive, while cosθ, tanθ are negative. In quadrant III, only tanθ is positive, while sinθ, cosθ are negative. How do you
How do you tell if a molecule will rotate plane polarized light?
Space and AstronomyHow do you know if a compound rotates plane polarized light? The d/l (or +/-) indicate the direction in which an optical active compound rotates the plane of polarization of plan-polarized light, that has to be determined by experiment to measure the optical rotation. What molecules can rotate plane polarized light? As stated, chiral molecules
What is the radius of a circle with 5 cm?
Space and Astronomyr = 0796 is right answer. What is the radius of 5 cm? The radius of the circle is 5cm. => Radius of the circle = 56cm. 2. What is the area of radius 5cm? A=πr2=722×(5)2=722×25=7550 cm2. How do you make a 5 cm radius circle? Steps of construction: With O as the centre and
How do you measure Lwh of a box?
Space and AstronomyHow do you measure a box? The first dimension to measure is length. Length is always the longest side of the box that has a flap. The next dimension is width. The width side also has a flap, but is always the side shorter than the length. Measure the height of the package. Height is
