Students rolled a glass marble and a baseball down an inclined plane, as shown below, and made observations.
what is the relationship between the potential and kinetic energy as the objects rolled down the inclined plane? question 7 options: when the potential energy remained the same, the kinetic energy increased. as the potential energy decreases, the kinetic energy increases. when the kinetic energy remained the same, the potential energy increased. as the kinetic energy decreases, the potential energy decrease.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
