The answer would have to be 8.47 m/s/s because the backwards pull + the rate of speed it is going would have to be added to get the answer to compensate for the backwards pull
Answer:
1.7 × 10^11 Pa
Explanation:
Please see the attachments below
Answer:
23.99N
Explanation:
Given:
Pressure created by the heart = 120mm of hg
converting the pressure into the standard unit of N/m²
1mm of hg =
now, 120 mm of hg in N/m² will be
120mm of hg =
also
given effective area = 15.0 cm² = 15 × 10⁻⁴m²
Now,
Force = Pressure × Area
thus,
Force exerted will be = × 15 × 10⁻⁴m²
or
Force exerted will be = 23.99N
