A milliradian (SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). ). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol ′, is a unit of angular measurement equal to 1 / 60 of one degree. [1] Since one degree is 1 / 360 of a turn, or complete rotation, one arcminute is 1 / 21 600 of a turn.
It may be in plural form as appropriate (for example, "it is 283 kelvins outside", as for "it is 50 degrees Fahrenheit" and "10 degrees Celsius").

Velocity is the speed in combination with the direction of motion of an object.Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.
For a sample motorcycle moving at 22 m/s (50 mph) that has a front wheel with a moment of inertia of 0.6 kg·m 2, turning the front wheel one degree in half a second generates a roll moment of 3.5 N·m. In comparison, the lateral force on the front tire as it tracks out from under the motorcycle reaches a maximum of 50 N.

Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The end product was shipped out of the valley 165 miles (266 km) to the Mojave railhead in 10-ton-capacity wagons pulled by "twenty-mule teams" that were actually teams of 18 mules and two horses each. [35] A twenty-mule team in Death Valley. The teams averaged two miles (3.2 km) an hour and required about 30 days to complete a round trip. [33]
Map of the earthquake and aftershocks at 12 May, showing location of major historical earthquakes. The earthquake occurred on 25 April 2015 at 11:56 am NST (06:11:25 UTC) at a depth of approximately 8.2 km (5.1 mi) (which is considered shallow and therefore more damaging than quakes that originate deeper in the ground), [28] with its epicentre approximately 34 km (21 mi) southeast of Lamjung ...
