Ayuda Al componer el vector a = [ 15 x – 12 y ] con los vectores b = [ b x – 17 y ], c =[ – 10x + c y] , d = [ 8 x – 10 y ], resulta un vector que solo tiene coordenada en el eje de las
abscisas, y su valor es de – 12. Determinar el módulo y dirección de los vectores b y c.

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?
