A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
It has a nearly round shape with the diameter varying between 11 and 18 km (6.8 and 11.2 mi) and giving an average value of 15 km (9.3 mi). [ 5 ] [ 14 ] The shores are winding and contain many small bays; there are many small sandy islands ( noko ), rocks and coral reefs off the coast with the size up to 600 m (2,000 ft). [ 3 ]
At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of approximately 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft 3. The following table illustrates the air density–temperature relationship at 1 atm or 101. ...
The iPad (5th generation) [3] (also referred to as the iPad 9.7-inch [4]) is a tablet computer developed and marketed by Apple Inc. After its announcement on March 21, 2017, conflicting naming conventions spawned a number of different names, including "fifth-generation iPad" or "iPad (2017)".
where θ 1 is the angle between the ray and the surface normal in the first medium, θ 2 is the angle between the ray and the surface normal in the second medium and n 1 and n 2 are the indices of refraction, n = 1 in a vacuum and n > 1 in a transparent substance.
The ninth-generation iPad was discontinued on May 7, 2024, with the announcement of the iPad Air (6th generation) and the iPad Pro (7th generation). It was the last iPad model to have a home button, Lightning port and headphone jack. [5] The iPad 9th generation was later replaced with the 10th generation in October 2022.
The original delta flowed into the Madura Strait, [12] but in 1890 a 12-km canal was made by the Dutch East Indies authority to redirect the Solo River into the Java Sea. [ 12 ] [ 13 ] This was done to prevent sedimentation of mud from filling the Madura Strait and thereby preventing sea access to the important port city of Surabaya .
