I remember having this question on a quiz a while back
Answer:
The absolute uncertainty is 10%.
Explanation:
The absolute uncertainty, sometimes referred to as absolute error, is the size of the possible range of values where by the actual or true value of a measurement probably lies.
The uncertainty of the 50 mL beaker is given as ± 10%. This implies that the volume recorded using the beaker will either be 10 % above or below the actual volume.
The absolute uncertainty ignores the direction of the error, whether above or below, and is mostly concerned with the magnitude of the error. We simply ignore the signs of the uncertainty and this will give the value of the absolute uncertainty.
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
