Why is Spica so bright?
Space and AstronomyWhy is Spica brighter than the sun? The light from Spica’s two stars, taken together, is on average more than 2,200 times brighter than our sun’s light. Their diameters are estimated to be 7.8 and 4 times our sun’s diameter. Spica is one of several bright stars that the moon can occult (eclipse). Is Spica
What are the properties of parallelograms?
Space and AstronomyThere are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. What are the 7 properties
How do Saturn’s moons affect the Rings?
Space and AstronomyCassini watched some of Saturn’s moons steal ring particles, and other moons contribute particles to the rings. Cassini found that much of the material for Saturn’s E-ring—a diffuse ring outside the bright, main rings—comes from the moon Enceladus, which is venting icy particles and gas into space as it orbits Saturn. How do Saturn’s moons
What is the complement of probability?
Space and AstronomyThe complement of an event is the event not occuring. The probability that Event A will notoccur is denoted by P(A’). The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩
What does the nebular theory predict?
Space and AstronomyThe nebular theory predicted the existence of the Kuiper belt 40 years before it was discovered! There were many more leftover planetesimals than we see today. Most of them collided with the newly-formed planets & moons during the first few 108 years of the Solar System. We call this the heavy bombardment period. What does
What is the effect of the tidal coupling between Earth and the moon?
Space and AstronomyThe Earth raises tidal bulges on the moon. As the moon rotated through these bulges, internal friction slowed the moon’s rotation until it achieved tidal coupling. What do the vesicular basalts tell you about the lunar surface? What do the features of vesicular basalts tell us about the evolution of the lunar surface? The holes
Where is the crater that killed the dinosaurs?
Space and AstronomyHidden below the waters of the Gulf of Mexico, the Chicxulub crater marks the impact site of an asteroid that struck Earth 66 million years ago. The most consequential outcome of this cataclysmic event was the fifth mass extinction, which wiped out about 80% of all animal species, including the nonavian dinosaurs. Where is the
Is firebase a tool?
Space and AstronomyGoogle Firebase is a Google-backed application development software that enables developers to develop iOS, Android and Web apps. Firebase provides tools for tracking analytics, reporting and fixing app crashes, creating marketing and product experiment. Is Firebase a backend tool? Firebase is a Backend-as-a-Service (Baas). It provides developers with a variety of tools and services to
What is five less than twice a number?
Space and AstronomyWhat is 5 less than a number? Video quote: The 5 5 less than to subtract. 5 from a number since we don't know what that number is we put in a variable. So 5 less than a number is n minus five. What does 5 more than twice a number mean? Next, “twice a
Do neap tides occur during a full moon?
Space and AstronomyNeap tides occur halfway between each new and full moon – at the first quarter and last quarter moon phase – when the sun and moon are at right angles as seen from Earth. What tides occur during a full moon? Spring tides always happen when the Moon is at the full or new phase,
