The components of the resultant will be: (18, 12)
In order to find the magnitude you have to apply the Pythagorean theorem:
√(18² + 12²) = √468 = 21.6
Therefore, the magnitude of the resultant vector is 21.6
The direction is given by the formula:
α = tan⁻¹(v_y / v_x)
   = <span>tan⁻¹(12/18)
   = 33.7°
Therefore, the direction will be 33.7° from the x-axis.</span>
        
             
        
        
        
 E = hf = hc/λ
 = (6.6 x 10^-34) × (3 × 10^8) ÷ (3.1 × 10^-7)
 =6.138 × 10^-32 J
