Where are reflecting telescopes used?
Space and AstronomyReflectors are used not only to examine the visible region of the electromagnetic spectrum but also to explore both the shorter- and longer-wavelength regions adjacent to it (i.e., the ultraviolet and the infrared). Where do we use reflecting telescopes? The late 20th century has seen the development of adaptive optics and lucky imaging to overcome

How big is Mars compared to the Earth?
Space and AstronomySize and Distance With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry. From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the

How is cork harvested?
Space and AstronomyThe plank is then separated from the tree, by inserting the edge of the axe between the strip and the inner bark. The axe is twisted between the trunk and the cork strip to be extracted. A horizontal cut defines the size of the cork plank to be removed and what is to remain on

Is Cotangent an odd or even function?
Space and AstronomyCosine and secant are even; sine, tangent, cosecant, and cotangent are odd. Even and odd properties can be used to evaluate trigonometric functions. Why is cot an odd function? We can determine whether each of the other basic trigonometric functions is even, odd, or neither, with just these two facts and the reciprocal identities. Thus

Is the sun in the middle of the Milky Way?
Space and AstronomyYes, the Sun – in fact, our whole solar system – orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way! The Milky
