A cylindrical piece of wood of height H, radius r, and uniform density rhoc is bobbing up and down in still water with its axis aligned vertically. The density of the water is rhow. Gravity acts vertically downward on the wood with magnitude mg, where m is the wood’s mass. Neglecting friction, the motion of the bobbing wood about its equilibrium depth can be described by A cos (ωt + φ), a function of time t. What is ω?

The density of a liquid could be found by using

If the speed of a particle triples ,by what factor does its kinetic energy increase?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
