A (cube, with a calculable volume of dimensions Xm=7 x Ym=7 x Zm=7), having density rho=80 kg/m³, is 80% (less than 100%) submerged in a fluid having density rho_fluid=1500 kg/m³. Find a) the tension in a string holding the object to the bottom of container holding the fluid (aside; this only makes sense if the buoyancy force exceeds the object's weight force), and b) the numerical value of the pressure at the top and the bottom of the object, including atmospheric pressure. Remember that: a) the buoyancy force depends only on the submerged volume, rather than the total volume of the object, and b) atmospheric pressure is 101325 pascal (Pa).

A spherical mylar balloon filled with Hydrogen gas, with density 0.0899 kg/m3 and having radius 7 meters is immersed in a gas having density X1=1.205 for the first 10 km and X2=2.489 for the second 10 km (with the upper atmosphere density smaller than the lower atmosphere density). Determine how long it takes the balloon to reach the top of the second layer. To do this, you will have to: a) find the net force on the balloon (assume the...

A box has a bottom with one edge 7 times as long as the other. If the box has no top and the volume is fixed at ?V, what dimensions minimize the surface area? dimensions = ________________Enter the dimensions as a comma-separated list, e.g., 3,sqrt(12),8. (Your answer may involve V.) The top and bottom margins of a poster are 2 cm and the side margins are each 6 cm. If the area of printed material on the poster is fixed at...
