Answer the following question given this paragraph: Summary Nuclear reactions are accompanied by large changes in energy, which result in detectable changes in mass. The change in mass is related to the change in energy according to Einstein's equation: E = (m)c2. Large changes in energy are usually reported in kiloelectronvolts or megaelectronvolts (thousands or millions of electronvolts). With the exception of 1H, the experimentally determined mass of an atom is always less than the sum of the masses of the component particles (protons, neutrons, and electrons) by an amount called the mass defect of the nucleus. The energy corresponding to the mass defect is the nuclear binding energy, the amount of energy released when a nucleus forms from its component particles. In nuclear fission, nuclei split into lighter nuclei with an accompanying release of multiple neutrons and large amounts of energy. Thecritical mass is the minimum mass required to support a self-sustainingnuclear chain reaction. Nuclear fusion is a process in which two light nuclei combine to produce a heavier nucleus plus a great deal of energy. Q: In which process do two light nuclei combine to produce a heavier nucleus and great energy? Choices: - general fusion - light fusion - certain fusion - nuclear fusion A:
nuclear fusion

Answer the following question given this paragraph: Carbon is a nonmetal in group 14 of the periodic table. Like other group 14 elements, carbon has four valence electrons. Valence electrons are the electrons in the outer energy level of an atom that are involved in chemical bonds. The valence electrons of carbon are shown in the electron dot diagram in the Figure below . Q: What do you call the electrons in the outer energy level of an atom that are involved in chemical bonds? Choices: - force electrons - helium electrons - transitions electrons - valence electrons A:
valence electrons

Answer the following question given this paragraph: Wave energy does the work of erosion at the shore. Waves erode sediments from cliffs and shorelines. The sediment in ocean water acts like sandpaper. Over time, they erode the shore. The bigger the waves are and the more sediment they carry, the more erosion they cause ( Figure below ). Q: What type of energy causes erosion at the shore? Choices: - tidal - potential - kinetic - wave A:
wave
