Y Part C What is the density of seawater at this pressure?

Calculate the absolute pressure at an ocean depth of 1.0 km. Assume that the density of Water Pwater is 1.025 x 103 kg / m3 and the atmospheric pressure, Patmosphere = 1.01 X 10Pa. (Use: Acceleration due to gravity, g = 9.8 m / s2) elect one: a. 1.01 x 107 Pa b. 1.02 x 106 Pa c. 1.11 X10 Pa

Sharks are generally negatively buoyant; the upward buoyant force is less than the weight force. This is one reason sharks tend to swim continuously; water moving past their fins causes a lift force that keeps sharks from sinking. A 92 kg bull shark has a density of 1040 kg/m3.a. What lift force must the shark’s fins provide if the shark is swimming in seawater?b. Bull sharks often swim into freshwater rivers. What lift force is required in a river?

B h A The picture shows a section of pipe within a closed system (not open at the ends). Water (density 1000 kg/m³) flows from left to right in the system. At point A, the pipe diameter is 60 cm, the speed of the water is 24 m/s, and the pressure is 1.3 atm. At point B, the pipe diameter is 2.4 m. The height difference h is 3.5m. What is the pressure at point B? (Hint, use continuity to determine the speed at point B, then use the Bernoulli equation.) O1.9 atm 1.3 atm 0.85 atm 3.8 atm 2.9 atm

Nail tips exert tremendous pressures when they are hit by hammers because they exert a large force over a small area. a. What force, in newtons, must be exerted on a nail with a circular tip of a diameter 1.25 mm to create a pressure of 3.1 × 109 N/m2? (This high pressure is possible because the hammer striking the nail is brought to rest in such a short distance.)  b. How many people of mass 72 kg would have to stand on this nail to exert this force? Round to the nearest integer.

You can chew through very tough objects with your incisors because they exert a large force on the small area equal to that of a pointed tooth. a. What pressure, in pascals, can you create by exerting a force of 520 N with your tooth on an area of 0.95 mm2?

A ball with a radius (25 cm) and mass (2 kg) is partially submerged beneath the surface of a fluid with a density of (1.5 g/cm3). If half the volume of the ball is beneath the fluid’s surface, what is the buoyancy force on the ball due to the fluid?

What is the force due to atmospheric pressure on the outside of a 0.5m × 0.25m window? N. Why doesn't this force break the window due to this force?

You can chew through very tough objects with your incisors because they exert a large force on the small area equal to that of a pointed tooth. a. What pressure, in pascals, can you create by exerting a force of 520 N with your tooth on an area of 0.95 mm2?
