3.2.-Calcula el valor de la fuerza resultante de cuatro fuerzas perpendiculares entre sí:
F1 = 9N (Norte)
F2 = 8N (Este)
F3 = 6N (Sur)
F4 = 2N (Oeste)

Determine the maximum r-value of the polar equation r =3+3 cos 0

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?
