Two compact sources of sound oscillate in phase with a frequency of 100 hz. at a point 5.00m from one source and 5.85 m from the other, the amplitude of the sound from each source separately is a. (a) what is the phase difference of the two waves at that point? (b) what is the amplitude (in terms of a) of the resultant wave at that point?

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)
