Answer:
0.139 rad
Explanation:
We use Snell's law , where if is the <em>refractive index</em> of the medium containing the <em>incident ray</em>, would be the <em>incident angle</em>, and if is the <em>refractive index</em> of the medium containing the <em>refracted ray</em>, would be the <em>refraction angle</em>, which we want, so we do:
And finally:
We then insert our values:
Answer:
400
Explanation:
can you help me with my question The surface of the Gilded Age was of great prosperity, while the interior was corrupt; the "gilding" or good exterior of the Gilded Age came from which of the following? A. Rebuilding the nation from the left over money from the War B. The technological advancements of the industrial revolution C. The mass movement of people from the country into the cities D. New monuments and buildings built in honor of the war heroes
Given: Weight W = 100 lbs convert to Kg = 45.36 Kg
Height h = 8 Ft convert to meter = 2.44 m
Time t =10 s
Required: Power output
Formula: P = W/t Work = Force x distance or Work = mgh
P = mgh/t
P = (45.36 Kg)(9.8 m/s²)(2.44 m)/10 s
P = 108.46 J/s
P = 0.15 Horsepower
Torque will produce rotation
