One imperial horsepower lifts 550 pounds (250 kg) by 1 foot (30 cm) in 1 second. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
The navigation message contains corrections for these errors and estimates of the accuracy of the atomic clock. However, they are based on observations and may not indicate the clock's current state. These problems tend to be very small, but may add up to a few meters (tens of feet) of inaccuracy. [7]
UTC-8 (AKDT) Point Barrow or Nuvuk is a headland on the Arctic coast in the U.S. state of Alaska, 9 miles (14 km) northeast of Utqiagvik (formerly Barrow). It is the northernmost point of all the territory of the United States, at 71°23′20″N 156°28′45″W, 1,122 nautical miles (1,291 mi; 2,078 km) south of the North Pole.
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. On the other hand, the penultimate equation becomes grossly inaccurate at great distances. If an object fell 10 000 m to Earth, then the results of both ...
Human power is the rate of work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans. World records of power performance by humans are of interest to work planners ...
Alaska historian Terrence Cole Since the completion of the Trans-Alaska Pipeline System in 1977, the government of the state of Alaska has been reliant on taxes paid by oil producers and shippers. Prior to 1976, Alaska's personal income tax rate was 14.5 percent—the highest in the United States. The gross state product was $8 billion, and Alaskans earned $5 billion in personal income. Thirty ...
The original Naismith 's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent. [1][4] It is included in the last sentence of his report from a trip. [1][8] Today it is formulated in many ways. Naismith's 1 h / 3 mi + 1 h / 2000 ft can be replaced by:
Other units are based on customary units, but use power-of-ten factors and metric prefixes. For example, distance to target for a U.S. submarine is expressed in kiloyards (kyd) rather than some combination of miles, yards, and feet. [70] Telephone transmission line length and loop distances are measured in kilofeet. [117]
