In radio astronomy, the unit of electromagnetic flux is the jansky (symbol Jy), equivalent to 10 −26 watts per square metre per hertz (= 10 −26 kg/s 2 in base units, about 8.8×10 −31 BTU/ft 2). It is named after the pioneering radio astronomer Karl Jansky. The brightest natural radio sources have flux densities of the order of one to one ...

Alaska is the least densely populated state, and one of the most sparsely populated areas in the world, at 1.2 inhabitants per square mile (0.46/km 2), with the next state, Wyoming, at 5.8 inhabitants per square mile (2.2/km 2). [76] Alaska is by far the largest U.S. state by area, and the tenth wealthiest (per capita income). [77]
Using an interval of 30 mi (50 km), the length is about 2,100 mi (3,400 km). The coastline paradox states that a coastline does not have a well-defined length. Measurements of the length of a coastline behave like a fractal , being different at different scale intervals (distance between points on the coastline at which measurements are taken).
At 26,338 square kilometres (10,169 sq mi), Rwanda is the world's 149th-largest country. [2] It is comparable in size to Haiti or the state of Massachusetts in the United States. [ 3 ] [ 4 ] The entire country is at a high altitude: the lowest point is the Rusizi River at 950 metres (3,117 ft) above sea level.

According to the United States Census Bureau, the city has a total area of 10.3 square miles (27 km 2), of which, 5.3 square miles (14 km 2) of it is land and 5.0 square miles (13 km 2) of it (48.63%) is water.
Nominal horsepower = 7 × area of piston in square inches × equivalent piston speed in feet per minute/33,000. For paddle ships, the Admiralty rule was that the piston speed in feet per minute was taken as 129.7 × (stroke) 1/3.38. [28] [29] For screw steamers, the intended piston speed was used. [29]
