The two forces shown act in the x-y plane of the t-beam cross section. if it is known that the resultant r of the two forces has a magnitude of 2.9 kn and a line of action that lies 17° above the negative x-axis, determine the magnitude of f1 and the orientation θ of f2.

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?
