Ablock oscillating on a spring has period t = 2.8 s . (note: you do not know values for either m or k. do not assume any particular values for them. the required analysis involves thinking about ) what is the period if the block's mass is doubled? (b) what is the period if the value of the spring constant is doubled? (c) what is the period if the oscillation amplitude is halved while m and k are unchanged?

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)
