Part A If you place a charged object next to an uncharged object that is a conductor, If you place a charged object next to an uncharged object that is a conductor, There is an attractive force between the two objects. There is a repulsive force between the two objects. There is no force between the two objects. The force depends on whether the charge is positive or negative.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

We have a colorless transparent liquid. it looks like water. we seperated it into a solid and a liquid by evaporration and condention was this a chemichal or a physical seperation a. chemical seperation b. physical seperation

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.
