I. Choose the Correct Answer 1. A particle on a spring executes simple harmonic motion. If the mass of the particle and the amplitude are both doubled then the period of oscillation will change by a factor of

Earth's Internal Structure When a meteorite impacts a planet or moon, its energy of motion (called kinetic energy)is transformed into heat energy. As Earth grew larger and larger from continual impacts, its temperature increased. Radioactive decay of materials like uranium, thorium and potassium also added heat
