A 3.15kg piece of wood (SG= .50) floats on water. What minimum mass of lead, hung from it by a string, will cause it to sink?
*note- please explain this in the simplest way possible if you can! thank you :)
A solid cube of unknown composition is seen floating upright in water with 30% of it above the surface. What is the density of the material?
I believe the answer is 0.70 g/cm^3.
A radiator contains 10 quarts of fluid, 30% of which is antifreeze. How much fluid should be drained and replaced with pure antifreeze so that the new mixture is 40% antifreeze?
Consider an object with height h, mass M, and uniform cross sectional area A floating upright in a liquid with density p.
a.) Calculate the vertical distance from the surface of the liquid to the bottom of the floating object at equilibrium.
b.) A downward force of magnitude F is applied to the top of the object. At the
