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

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
