When nonionizing radiation is absorbed by matter, it usually becomes which type of energy? A. Mechanical B. Chemical C. Thermal D. Electromagnetic

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

magnified images possible images can be real = projected onto a screen

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
