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 dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j. suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon
