If a telescope with an objective lens of ten feet focal length is used with an eye piece of one quarter inch focal length what would the resulting magnification be?

The magnification (MA) equals the focal length of the objective lens (fo) divided by the focal length of the eyepiece (fe), which is this: MA = fo / fe = 10 feet / .25 inches = 120 inches / .25 inches = 480 A link to the Wikipedia article on magnification is included.

Who invented the reflective telescope?
Isaac Newton invented it, as he understood from his study of optics that a large lens, or mirro, gathered more light than a small one, and the objective lens of the best telescopes of the time rarely exceeded about 30mm (inch and a quarter). The principal worked, allowing him to see many more celestial bodies than the telescopes of the time, though usually with a smaller image, overall.
Why did they invented the telescope?
The telescope was introduced to astronomy in 1609 by the great Italian scientistGalileo Galilee, who became the first man to see the craters of the moon, and who went on to discover sunspots, the four large moons of Jupiter, and the rings of Saturn. Galileo's telescope was similar to a pair of opera glasses in that it used an arrangement of glass lenses to magnify objects. This arrangement provided limited magnifications to 30 times for Galileo and a narrow field of view; Galileo could see no more than a quarter of the moon's face without repositioning his telescope.
How Many fat quarters are in a yard of fabric?
There are 4 fat quarters in a yard of fabric.When fabric comes off the bolt it is stored on, it is folded in half so that the selvedge ends are touching. To cut a fat quarter, a half yard is cut from the bolt of fabric. This half yard is then cut in half along the fold, resulting in a quarter yard of fabric (half of a half is a quarter).The fat quarter is used often in quilting because it provides more usable space for quilters than a standard quarter yard cut. A standard quarter yard is 9 inches wide, by the width of fabric on the bolt (anywhere between 40-44 inches is standard width of fabric). A fat quarter is wider, but less long at 18 inches wide by 20-22 inches long.Even though the fat quarter has a different length and width than a standard quarter yard cut, it still represents a quarter yard of fabric. Since four quarters make a whole, each yard of fabric can be cut into exactly 4 fat quarters.

What is the value of a two headed quarter?
A two headed quarter is not something that was done at the mint, it is a novelty item, generally with high enough magnification you can see the seam that the two coins were joined together. They aren't rare and really aren't worth any more than a quarter.

That would be the equivalent of a half note. In other words, a sound lasting two beats (assuming a quarter note gets a beat).
