Why is the moon important?
Space and AstronomyThe Latest. The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet’s wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. What would happen without moon? It
Does every solar system have an asteroid belt?
Space and AstronomyFull image and caption New observations from NASA’s Spitzer Space Telescope indicate that the nearest planetary system to our own has two asteroid belts. Our own solar system has just one. Do most solar systems have asteroid belts? The vast majority of asteroids in the solar system are found in a region of the solar
What kind of galaxy is the oldest?
Space and AstronomyThe oldest known galaxy in existence remains GN-z11, which formed around 400 million years after the Big Bang, as previously reported by Live Science’s sister site Space.com. Researchers discovered the ancient galaxy after finding a photo of it in the ALMA archive. Which type of galaxy is the oldest? Elliptical galaxies, such as M87, are
Can three angles be complementary?
Space and AstronomyThree or more angles cannot be complementary even if their sum is 90 degrees. If two angles are complementary, each angle is called “complement” or “complement angle” of the other angle. Two acute angles of a right-angled triangle are complementary. What does it mean when three angles are complementary? Three angles or more angles whose
What are the relationships between the segments in circles?
Space and AstronomyThe first scenario is when you have two secant segments that intersect each other inside the circle. When you have intersecting segments such as these, the relationship is that the product of the segment pieces of one segment is equal to the product of the segment pieces of the other. What is the relationship between
What is the difference between direct variation and inverse variation?
Space and AstronomyDirect variation occurs when an increase in one variable is results with an increase in value of the other variable. Inverse variation occurs when an increase in one variable is results with a decrease in value of the other variable. How do you tell the difference between direct and inverse variation? For direct variation, use
What are space tethers made of?
Space and AstronomyTethers are usually made of thin strands of high-strength fibers such as Spectra or Kevlar. Any space tethered system is intimately connected to the gravitational force field. Conducting tethers offer the additional capability to interact with the magnetic and electrical force fields. Are space tethers real? Space tethers are long cables which can be used
How do you find the balance point of a triangle?
Space and AstronomyThe three medians of a triangle intersect at its centroid. The centroid is the triangle’s balance point, or center of gravity. (In other words, if you made the triangle out of cardboard, and put its centroid on your finger, it would balance.) Which center is the balancing point of the triangle? Video quote: Now the
Why is my finder scope upside down?
Space and AstronomyThere is nothing wrong with your finder scope or your telescope. The images will appear upside down and reversed left to right. This is normal. You can use a correct image diagonal to make the field of view appear the way you would see it with your naked eye, but it’s really not necessary. How
Which trig functions are continuous?
Space and AstronomyThe function sin(x) is continuous everywhere. The function cos(x) is continuous everywhere. How many trigonometric functions are continuous? six basic trigonometric Theorem 1.6. 1 implies that the six basic trigonometric functions are continuous on their domains. In particular, sin x and cos x are continuous everywhere. Is Secant function continuous? The cosecant; secant and cotangent
