Light of a given wavelength is used to illuminate the surfacce of a metal, however, no photoelectrons are emitted. In order to c
ause electrons to be ejected from the surface of this metal you shouldA. use light of the same wavelength but increase its intensity.B. use light of a shorter wavelength.C. use light of the same wavelength but decrease its intensity.D. use light of a longer wavelength.
The piece of paper has less mass and will glide down the window, whereas the textbook will go straight to the ground. Since the textbook has more mass and less ways of it being able to 'glide' the textbook will hit the ground first.
