Aforce fix).0x25.0x) n acts on a particle. how much work (in j) does the force do on the particle as it moves from x = 4.0 m to x = 6.0 m? 203.33 (a) (b) picking a convenient reference point of the potential energy to be zero at x0, find the potential energy for this force. (use the following as necessary: x. assume u(x) is in joules and x is in meters.

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.

An object weigh 40n in air ,weigh 20n when submerged in water,and 30n when submerged in a liquid of unknown liquid density.what is the density of unknown of liquid?
