Do all galaxies move at the same speed?
Space and AstronomyIt’s distance dependent – further away = faster moving. So not the same speed, but from every viewpoint in the universe the same pattern of faster when further away. Do some galaxies move faster than others? Video quote: Space is expanding by roughly 70 kilometers per second per megaparsec. So these other galaxies are moving
What forces act on a satellite in orbit?
Space and AstronomyWhen a satellite is in circular orbit, gravity is the only force acting on it, which means that the centripetal force and gravity must be equal: Fc = Fg . What forces act on an object in orbit? In the case of an orbiting planet, the force is gravity. The situation is illustrated in Figure
What is isosceles triangle example?
Space and AstronomySome popular examples of an isosceles triangle in real life are a slice of pizza, a pair of earrings. The equal sides of an isosceles triangle are known as the ‘legs. ‘ The third and unequal side of an isosceles triangle is known as the ‘base. What is an isosceles triangle? An isosceles triangle therefore
What is the function of the chromosphere?
Space and AstronomyThe chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona. What happens in chromosphere? The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. At these higher temperatures hydrogen emits light that gives off a reddish
What does MRAM stand for in calculus?
Space and AstronomyMidpoint Rectangular Approximation Method (MRAM) Areas are: x=1 to 2: ln(1.5) × 1 = 0.405465… How do you calculate MRAM in calculus? Video quote: Okay. So I want two rectangles of equal width using MRAM MRAM is midpoint area approximation so the mid the midway point then would be at negative one point 5. And
How far is the closest solar system to Earth?
Space and Astronomyabout 4.35 light-years4.35 light-years from Earth, according to NASA. How long would it take to get to our nearest solar system? If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity,
How do you find the length of a circle?
Space and AstronomyHow do you calculate the length of a circle? Video quote: The length of the circumference equals twice the radius. By pi. Or in other words the diameter of the circumference. How do you find the unknown length of a circle? Video quote: To figure out what the length of the diameter is we can
Why are radio telescopes so large?
Space and AstronomyRadio telescopes have to be much larger than optical telescopes because the wavelengths of radio waves are so much larger than the wavelengths of visible light. Why do radio telescopes have to be very large quizlet? Why are Radio Telescopes larger than than optical telescopes? Radio wavelengths are much longer thus low energy. Dish must
What do alternate interior angles equal?
Space and AstronomyThese angles are congruent. The sum of the angles formed on the same side of the transversal which are inside the two parallel lines is always equal to 180°. In the case of non – parallel lines, alternate interior angles don’t have any specific properties. Do alternate interior angles add up to 180? Unless the
Which Quadrilaterals can always be inscribed in a circle?
Space and AstronomyCyclic QuadrilateralsA cyclic quadrilateral is a quadrilateral that can be inscribed in a circle. Which quadrilateral Cannot be inscribed in a circle? All triangles have a circumcircle, but not all quadrilaterals do. An example of a quadrilateral that cannot be cyclic is a non-square rhombus. The section characterizations below states what necessary and sufficient conditions
