Eratosthenes of Cyrene [born ca. 276 BCE, Cyrene, Libya-died ca. 194 BCE, Alexandria, Egypt] made the first measurement of the size of Earth for which any details are known. His method is illustrated. On the first day of summer he observed that the sun was directly overhead at noon in Cyrene. At the same time the sun was 7.2° from overhead in Alexandria, which is distance d north of Cyrene. From the data, estimate

Graph below represents the force on a 12 kg air mass as it passes through a jet engine. Immediately after entering the engine, the force is 9,039 N, and the force tapers linearly to zero once the air reaches the back of the engine 2.3 m later. If the air enters the engine with velocity 252 m/s, what is its exit velocity? (Please answer to the fourth decimal place - i.e 14.3225)
Two points, A & B, are 3,134.50 meters apart. From a third point, C, on the line between A and B, and 1,992.25 meters from A, the measured vertical angle to A is +35°28' and that to B is -15°14'. Determine the difference in elevation between A and B making due allowance for the effects of curvature and atmospheric refraction
