the force that attract any object to another =gravity
Answer:
F = -2527.35 N
Explanation:
Given,
mass per unit time = 58.1 Kg/s
Speed of the water = 43.5 m/s
Final momentum = 0 kg/s
Force = Change in momentum
F = Final momentum - initial momentum
F = 0 - initial momentum
F = -2527.35 N
Hence, the Force exerted is equal to F = -2527.35 N
Answer:
the paper ball falls faster and the unfolded paper falls at a slower rate
Explanation:
this is because gravity is pulling both objects down to the ground and hence they are falling. Both objects have the same mass and weight but the resultant force of the paper ball is smaller than that of the unfolded paper. The unfolded paper has a larger surface area and so a larger force is acted upon it, meaning there is more air resistance. This shows that the paper ball falls faster than the unfolded paper.
Answer:
The intralveolar pressure is 1 mmHg
Explanation:
The transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure. It is this gradient between pressures that allows the air to flow during human ventilation.
Writing this into an equation it means that, Ptp = Palv - Pip, so from there we have Palv = Ptp + Pip, or Palv = 5 mmHg - 4 mmHg = 1 mmHg.
Answer:
equal to the force of gravity, F= mg
