Which observation supports a model of the nature of light in which light acts as a wave?
A. Constructive interference B. Temperature change C. Blackbody radiation D. Photoelectric effect
There are three possible ways to solve this problem: The first one is: 0.70*[(12*9.81) - |F|*sin 30] = |F|*cos 30 or The second one is: |F|*[{0.70*(sin 30)}+(cos 30)] = 0.70*(12*9.81) or The third one is|F| = [{0.70*(12*9.81)}/{0.35 + cos 30}]
But this will all result to= 67.77 N
