Calculate the minimum frequency of ultrasound that will allow you to see details as small as 0.250 mm in human tissue. (The average propagation speed for sound in body tissue is 1540 m/s) Group of answer choices 9.00 X 10^6 Hz 6.16 X 10^6 Hz 8.26 X 10^6 Hz 5.26 X 10^6 Hz

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)
