How many curves does an oval have?
Space and Astronomyone flat curved faceone flat curved face. An oval shape does not have a common distance from the center (radius) like the circle. Does an oval have curved lines? The definition of a side or edge is a line connecting two vertices or points. An oval does not have any straight lines, only curves so
What is a net of a 3d object?
Space and AstronomyThe net of a 3D shape is what it looks like if it is opened out flat. A net can be folded up to make a 3D shape. There may be several possible nets for one 3D shape. You can draw a net on paper, then fold it into the shape. The net of a
How does the armillary sphere work?
Space and AstronomyHow does an armillary sphere work? Held stationary at the centre is a small brass sphere representing the Earth. About it rotate a set of rings representing the heavens – the celestial sphere – one complete revolution approximating to a day or 24 hours. How is the armillary sphere used? An armillary sphere is basically
Are Vanishing points always on the horizon?
Space and AstronomyYour vanishing point will always occur on the horizon line. The road and buildings around you will direct you to your vanishing point. Follow the slants of their roofs up or down. Your vanishing point is where those lines converge. When can a vanishing point not be on the horizon? If one axis of a
What is the official name of the Milky Way galaxy?
Space and AstronomyThe term “Milky Way”, a term which emerged in Classical Antiquity to describe the band of light in the night sky, has since gone on to become the name for our galaxy. Like many others in the known Universe, the Milky Way is a barred, spiral galaxy that is part of the Local Group –
Are the moon phases the same in the northern and southern hemisphere?
Space and AstronomyYes, everyone sees the same phases of the Moon. People north and south of the equator do see the Moon’s current phase from different angles, though. If you traveled to the other hemisphere, the Moon would be in the same phase as it is at home, but it would appear upside down compared to what
What is the perimeter of composite figure?
Space and AstronomyPerimeter of Composite Figures To find the perimeter of a composite two-dimensional figure, add the lengths of the sides. How do you find the perimeter and area of a composite figure? Add up the length of all the sides to get the perimeter. Calculate the area of the composite figure by adding up the areas
Why is the umbra so small?
Space and Astronomy“Why is the shadow of an eclipse a lot smaller than the Moon?” Because the Sun is larger than the Moon, so the Moon’s umbra gets smaller as it falls away from the Moon, like a cone shape. The penumbra gets bigger, just like you would expect, but the umbra gets smaller. You can see
What was discovered with the refracting telescope?
Space and AstronomyGalileo Galilei’s discovered the Galilean satellites of Jupiter in 1610 with a refracting telescope. What other things were developed using the refracting telescope design? The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses. What was
