Please help me A man pulls a crate on a horizontal floor with the help of a rope (figure 7.7). The pulling force of the rope is 200N at the 30 "angle with the horizontal.
Calculate the work done to move the crate by 5.0m.​

Which of the following is an example of units for speed

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)
