What is its power output? Number 22.5 here is a hint availablet w the hint by clicking on the om divider der bar again to hide the hint. on the Close Previous-) Give Up & View Solution Check Answer ONext Exit

Explanation / Answer

here,

intensity , I = 150 W/m^2

the area of measuring device , A = 0.035 * 0.04 m^2

the power output , P = I * A

P = 150 * 0.035 * 0.04 W

P = 0.21 W

the power output is 0.21 W
