A 700.0 N window washer is standing on a scaffold supported by ropes at each end. The scaffold weighs 200.0 N and is 3.00 m long. What is the force in each rope when the window washer stands 1.00 m from one end?

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
