What is an example of one to one correspondence?
Space and Astronomy1 to 1 correspondence is the skill of counting one object as you say one number. For example, if you are counting objects, you point at the first item and say ‘1’, then point to the second and say ‘2’ and so on. Sounds simple! Which of the following is an example of one-to-one correspondence?

How long is a solar cycle?
Space and Astronomyapproximately 11-year11-year cycle experienced by the Sun. During the solar cycle, the Sun’s stormy behavior builds to a maximum, and its magnetic field reverses. What is the length of a solar cycle? about 11 years solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences

How do you find the postulate?
Space and AstronomyIf you have a line segment with endpoints A and B, and point C is between points A and B, then AC + CB = AB. The Angle Addition Postulate: This postulates states that if you divide one angle into two smaller angles, then the sum of those two angles must be equal to the

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

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
