Answer:

159.01 mmHg

Explanation:

position of Heart = 2m  below the top of the head  given that the neck is fully extended

<u>Determine the minimum diastolic pressure </u>

Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m

                                               = 21200 kg/m^2

convert the value to Pa

21200 kg/m^2 = 21200 Pa

( 1 pa = 0.00750062 mmHg )

Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg
