2. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2] It is a type of polyphase system employing three wires (or ...

3. Mathematics of three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Mathematics_of_three-phase...

   Mathematics of three-phase electric power. One voltage cycle of a three-phase system, labeled 0 to 360° (2π radians) along the time axis. The plotted line represents the variation of instantaneous voltage (or current) with respect to time. This cycle repeats with a frequency that depends on the power system.

4. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   The power-to-weight ratio (specific power) formula for an engine (power plant) is the power generated by the engine divided by the mass. Weight in this context is a colloquial term for mass. To see this, note that what an engineer means by the power-to-weight ratio of an electric motor is not infinite in a zero gravity environment.

5. Exponentiation - Wikipedia

   en.wikipedia.org/wiki/Exponentiation

   The base 3 appears 5 times in the multiplication, because the exponent is 5. Here, 243 is the 5th power of 3, or 3 raised to the 5th power. The word "raised" is usually omitted, and sometimes "power" as well, so 3 5 can be simply read "3 to the 5th", or "3 to the 5".

6. Calories Burned Walking: 1 Mile, 1 Hour, Calculator - Healthline

   www.healthline.com/health/calories-burned-walking

   The equation is: calories burned = BMR x METs/24 x hour. For example: A 35-year-old woman who weighs 150 pounds, is 5 feet 5 inches tall (BMR = 1,437), and walks for 60 minutes at 3.0 mph (3.5 ...

7. Microsoft PowerToys - Wikipedia

   en.wikipedia.org/wiki/Microsoft_PowerToys

   Power Calculator could store and reuse pre-defined functions, of any arity. For example, a function could be set by cube(x) = x * x * x, and later it could be used in an expression like 5 + cube(4). It did not evaluate every time an operator was entered. Rather, the entire expression must be entered for calculation.

8. Intensity (physics) - Wikipedia

   en.wikipedia.org/wiki/Intensity_(physics)

   Intensity (physics) In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m 2 ), or kg ⋅ s −3 in base units. Intensity is used most frequently ...

9. Fourth power - Wikipedia

   en.wikipedia.org/wiki/Fourth_power

   In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n4 = n × n × n × n. Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares. Some people refer to n4 as n “ tesseracted ”, “ hypercubed ”, “ zenzizenzic ...
