What would happen if the Earth was tilted like Uranus?
Space and AstronomyIf Earth’s axis was tilted like that of Uranus, the days and the seasons would be very different. On Earth only the poles have perpetual darkness during winter and perpetual daylight during summer. With an axial tilt like Uranus, the Equator and the Arctic / Antarctic circles are almost at the same latitude. What would
Do calla lilies come in purple?
Space and AstronomyMany hybrid purple calla lilies come in purple shades with strong pink or lavender overtones. “Amethyst” lives up to its name with a saturated, bright lavender hue. “Dark Eyes” has the same vivid lavender, but only on the top half of the flower, with the colors fading to cream on the lower half. Can calla
What is Cpctc geometry?
Space and AstronomyGeometry. CPCTC stands for “corresponding parts of congruent triangles are congruent” and tells us if two or more triangles are congruent, then their corresponding angles and sides are congruent as well. What is Cpctc and example? It means that if two trangles are known to be congruent , then all corresponding angles/sides are also congruent.
What is the reciprocal of cos?
Space and AstronomyThe secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle. What is the reciprocal of tan? cotangent Tan is the ratio of the opposite side to the Adjacent side. cotangent is the reciprocal of tan that is the
How do you know if a geometric series converges?
Space and AstronomyIn fact, we can tell if an infinite geometric series converges based simply on the value of r. When |r| < 1, the series converges. When |r| ≥ 1, the series diverges. How do you tell if a geometric series is convergent or divergent? Geometric series: A geometric series is an infinite sum of a
Why does the moon perfectly cover the sun?
Space and AstronomyEven though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. During a total solar eclipse, the Moon passes between Earth and the Sun. This completely blocks out the Sun’s light. Can moon fully cover
How many tails do comets have?
Space and AstronomyTwo TypesA Comet Has Two Types of Tail The plasma tail comprises electrons and ions that are ionized by the sun’s ultraviolet radiation. The dust tail consists of micrometer-scale particles. The dust tail is wide and slightly bent because of the pressure of the light from the sun and the orbital action of the comet’s
What is Mare made of?
Space and Astronomy(Together with the bright lunar highlands, they form the face of the “man in the moon.”) Samples of lunar rock and soil brought back by Apollo astronauts proved that the maria are composed of basalt formed from surface lava flows that later congealed. What is mare material? By definition, mare materials (1) form generally smooth
What is positive and negative zero error in screw gauge?
Space and AstronomyIf the zero on the circular scale is below the reference line then the error is positive. If the zero on the reference line is above the reference line then the error is negative. Zero correction can be done by adding the same number of the zero error but with the opposite sign. What is
