A 60-kg person's two feet cover an area of A=146 cm2. Assume the person is at rest. If the person stands on one foot, what is the pressure under that foot (Pa)?. Consider g 10 m/s?. A. 328767 B. 493151 C. None D. 164384 E. 82192

1. Suppose a person is 182 cm tall. A typical blood pressure is often given as 110/70 mm Hg, with a mean pressure of 80 mm Hg. A. Do you think this is the gauge pressure or absolute pressure? Why? If the pressure at the top of the head is about 39 mm Hg, how far away is this person's head from the heart? Assume the density of blood is about 6% higher than that of water. t, What then would be the blood pressure.of this 6, person at their feet? b. Suppose this person suffers a puncture wound around the same height as the heart where the opening is about 3 mm in diameter. How far could blood shoot from their body assuming it comes out horizontally with 0 m/s initial horizontal velocity? %3D = 0.754 Since horizontal velocity is zero it will not go eny for than body Please explain the variábles used in the equation to solve for F= P.A in partad of this question.

A ball with a mass of 2000 g is floating on the surface of a pool of water. What is the minimum volume that the ball could have without sinking below the surface of the water? (Note that water has a density of 1.00 g/cm³.) A. 2 cm³ B. 1000 cm³ C. 2000 cm³ D. 9.8 cm³ 4

A child is playing with a 0.5 kg ball in the swimming pool. The ball is made of a stiff rubber and has a radius of .25 m. Assume the volume of the ball does not change when held under water. What downward force must the child exert on the ball to hold it in equilibrium just below the surface of the water? a. b. How does this answer change if the child was holding the ball near the bottom of the pool (1.5 m down)?

4. A raft is made of 12 logs lashed together. Each is 30.5 cm in diameter and has a length of 6,00 m. How many people (whole number) can the raft hold before they start getting their feet wet, assuming the average person has a mass of 66.0 kg? Do not neglect the weight of the logs. Assume the density of wood is 600 kg/m3 People (whole number) 741 n na741 na

Some jellyfish can eject stingers with remarkable force and speed. One species does this by building up a 15 MPa gauge pressure that pushes against the base of a 2.0-μm-diameter stylet, forcing it outward.a. What force does the excess pressure exert on the stylet?b. The mass set into motion is a tiny 1.0 × 10-12 kg. What is the resulting acceleration?

5. DETAILS 777777.78 Pa MY NOTES A 70.00kg ballroom dancer wearing high heels accidentally steps on her partner's foot. If her entire weight was momentarily supported by the heel of her shoe, which has a surface area of 0.90 cm², what amount of pressure does this apply to her partner's foot? 762.22 Pa 76222.22 Pa 7622222.22 Pa ASK YOUR TEACHER Suppose she instead stepped on her partner's foot with her forefoot instead of her heel (i.e., larger surface area). Would the pressure on her partner's foot be greater, less than, or equal to if she stepped on her partner with her heel? The pressure from the forefoot would be greater than the pressure from her heel. The pressure from the forefoot would be equal to the pressure from her heel. The pressure from the forefoot would be less than the pressure from her heel.

When water freezes, it expands by about 9.00%. What would be the pressure increase inside your automobile's engine block if the water in it froze? (The bulk modulus of ice is 2.00 x 109 N/m2.) a. 1.8 x 10^8 N b. 1.8 x 10^8 Pa c. 2.22 x 10^10 N d. 2.22 x 10^10 Pa
