WILL GIVE BRAINLIEST AND 50 POINTS!
It takes 63 W to power a ceiling fan. The energy output of the fan is 50 W. Calculate the efficiency of the fan. Round your answer to the nearest percentage.

_%

Correct  η = 79 %

Explanation:

The efficiency is calculated as the quotient of output and input power

η = (Pout / Pin) · 100 %

η = (50 / 63) · 100 = 0.7936 · 100 = 79.36 ≈ 79 %

η = 79.36 ≈ 79 %

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
