One way to monitor global warming is to measure the average temperature of the ocean. researchers are doing this by measuring the time it takes sound pulses to travel underwater over large distances. at a depth of 1000 m, where ocean temperatures hold steady near 4°c, the average sound speed is 1480 m/s. it's known from laboratory measurements that the sound speed increases 4.0 m/s for every 1.0°c increase in temperature in one experiment, where sounds generated near california if the smallest time change that can be reliably detected is 1.0 s, what is the smallest change in average temperature that can be measured? express your answer with the appropriate units. ?
