The heavily computational AP Physics B course served as the College Board's algebra-based offering for four decades. As part of the College Board's redesign of science courses, AP Physics B was discontinued; therefore, AP Physics 1 and 2 were created with guidance from the National Research Council and the National Science Foundation.

Hull speed can be calculated by the following formula: where is the length of the waterline in feet, and is the hull speed of the vessel in knots. If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m −½.
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
AN/UYQ-70 (Q-70) is the specification for a family of United States Navy display workstations.. Starting in 1991, it replaced the AN/UYA-4 and AN/UYQ-21 (series) displays and various submarine combat system displays: AN/BQQ-5(V) Control Display Console (CDC), Improved Control Display Console (ICDC), Mk 81 Mod(v) Combat Control System control and display consoles and various navigation and ...
Agrophysics – the study of physics applied to agroecosystems. Soil physics – the study of soil physical properties and processes. Cryogenics – cryogenics is the study of the production of very low temperature (below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures.
The first known outboard motor was a small 11 pound (5 kg) electric unit designed around 1870 by Gustave Trouvé, [9] and patented in May 1880 (Patent N° 136,560). [10] Later about 25 petrol powered outboards may have been produced in 1896 by American Motors Co [9] —but neither of these two pioneering efforts appear to have had much impact.
A United States Coast Guard Charter Boat Captain's Credential refers to the deck officer qualifications on a Merchant Mariners Credential which is a small book that looks similar to a passport and is issued by United States Coast Guard for professional mariners in the United States commanding commercial passenger vessels up to 100 gross tons as a Master, captain or skipper.
German submarine U-69 was the first Type VIIC U-boat of the German Navy (Kriegsmarine) during World War II.This meant that compared to previous U-boats, she could travel further afield for longer, with a payload of fourteen torpedoes, an 8.8 cm (3.5 in) deck gun for smaller vessels and a flak gun for use against aircraft.
