Apainter sits on a scaffold that is connected to a rope passing over a pulley. the other end of the rope rests in the hands of the painter who wants to lift the scaffold. she plans to pull downward on the loose end of the rope, thinking that the scaffold will then rise vertically with her along for the ride. the scaffold has a mass of 52 kg, and her mass is 63 kg. the painter pulls downward on the rope with a force of 600.0 n, while she and the scaffold are hanging from the other end above the ground. (a) what is the net acceleration on the system consisting of the painter and the scaffold

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
