Notice that all the initial spring potential energy was transformed into gravitational potential energy. if you compressed the spring to a distance of 0.200 m , how far up the slope will an identical ice cube travel before reversing directions? note that the spring is compressed twice as much as in the original problem.

The masses of the objects and their densities

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then   

Well it depends on the object or substance
