G.com what is the mass of a gold bar that is 7.379 × 10–4 m3 in volume
tiny-mole [99]
<span>7.379 * 10^(-4) is measured, hence prone to error, either human error or via measuring device. In this case,
100 cm = 1 m is written in stone and is unquestionable.
 The density of the gold is 19.3 g/cm^3 and could be an approximation.
 The approximation is good to at least one night.</span>

A engineer measures the peak power output is 0.3227MW what is the peak power output in kilowatts ?
Lana71 [14]
<h3>Answer:</h3>

322.7 kW

<h3>Explanation:</h3>
  • Power refers to the rate at which work is done.
  • Therefore; Power = Work done ÷ time
  • It is measured in joules per seconds or Watts

In this case, we are required to convert 0.3227 MW to kilowatts

We need to know that;

  • 10^6 watts = 1 Megawatts(MW)
  • 10^3 Watts = 1 kilowatts (kW)

Therefore;

10^3 kW = 1 MW

Therefore, the suitable conversion factor is 10^3kW/MW

Hence;

0.3227 MW is equivalent to;

   = 0.3227 MW × 10^3kW/MW

   = 322.7 kW

Thus, the peak power output is 322.7 kW
