Asmall drone has a straight wing with the following characteristics: wingspan 62", tip chord 6.25" fuselage chord 11.75". the width of the aircraft along the wing is constant and equal to 9 inches assume the trailing edge angle is zero. assume the wing extends through the fuselage. calculate: the chord as a function of y, c(y) (10 points) a. (5 points) the reference area b. the aspect ratio (5 points) d. mean aerodynamic chord (5 points) the location of the mean c. aerodynamic chord (5 points) the pitching moment about the center of pressure.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ∆t. the resistance of the coil is r, and the total charge is q = i∆t, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly “swiped” past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be “swiped” through the reader at exactly the right speed? why or why not?
