- The specific gravity of honey is 1.44. A cylindrical container of honey 10 feet [ft] deep is inside a dome pressurized to a surface pressure of 0.06 atmospheres [atm] on the surface of Pluto. The total pressure at the bottom of the container is 65 millimeters of mercury [mm Hg]. What is the gravitational acceleration of Pluto, in units of meters per second squared m/s2?You are preparing some apparatus for a visit to a newly discovered planet Caasi having oceans of glycerine and a surface acceleration due to gravity of 5.40 m/s2. If your apparatus floats in the oceans on earth with 30.0 % of its volume submerged, what percentage will be submerged in the glycerine oceans of Caasi?james cameron piloted a submersible craft to the bottom of the challenger deep, the deepest point on the oceans floor, 11,000m below the surface. what was the total inward force on the 1.1-m-diameter pilot sphere in which cameron sat?
- Drag Force: A spherical particle of radius 5.9 cm and a mass of 226 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) The position of the particle is given by x (t) 1 In (1+ bvot), where x is its position and t is the elapsed time. The initial speed vo is 27.8 m/s, and the constant b is 0.3 m-1. (b) What is the velocity of the particle after 3.3 seconds? (c) What is the acceleration of the particle after 3.3 seconds?A diver has a mass of 91 kg and a volume of 0.04 m^3. What is the downwards acceleration, in m/s^2, experienced by the diver while he is in the ocean?While workers spray paint the ceiling of a room, numerous small paint aerosols are dispersed into the air. Eventually, these particles will settle out and fall to the floor or other surfaces. Consider small spherical paint particles of diameter D = 10 μm and specific gravity of 1.2. Determine the time it would take this particle to fall 2.4 m from near the ceiling to the floor. Assume that the air within the room is motionless.
