Atypical flying insect applies an average force equal to twice its weight during each downward stroke while hovering. take the mass of the insect to be 10 g, and assume the wings move an average downward distance of 1.0 cm during each stroke. assuming 100 downward strokes per second, estimate the average power output of the insect.

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
