Answer :
1968.75x10^-4 w is the power output of the device at ultrasound of intensity 175 w/m2 is produced by the rectangular head of a medical imaging device measuring 3.00 cm by 6.00 cm.
let given,
ultrasound of Intensity = 175 W/m²
Area ,A = 4.572.5x10^-4 m²
power, p = ?
Intensity = power / Area
power = Intensity x Area
P = IXA
P = 175 W/m² X 4.572.5x10^-4 m²
P = 1968.75x10^-4 w
the power output will be 1968.75x10^-4 w
