Students are measuring the volume of an irregular solid using a graduated cylinder. They place the solid into the cylinder which already contains 50.2 mL of water, and the water levels rises to 75.4 ml Calculate the volume of the irregular solid to the nearest tenth of a mL.

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.
