Q: What particles are formed from a neutron in beta decay? Read this paragraph and choose the correct option from the provided answers: In beta decay, an electron and a proton form from a neutron (another unusual particle, called an antineutrino, is also produced). Only the electron is emitted from the nucleus. How does this change the atomic number and atomic mass of the atom?. Choices: - rust and proton - mucus and a proton - atom and proton - electron and a proton A:
electron and a proton

Q: What action, performed multiple times daily, is the single biggest use of water in the home? Read this paragraph and choose the correct option from the provided answers: It's easy to save water at home. If you save even a few gallons a day you can make a big difference over the long run. The best place to start saving water is in the bathroom. Toilet flushing is the single biggest use of water in the home. Showers and baths are the next biggest use. Follow the tips below to save water at home. Choices: - taking showers - watering plants - washing clothes - flushing the toilet A:
flushing the toilet

Q: What happens to energy in a closed system? Read this paragraph and choose the correct option from the provided answers: Energy is conserved in a closed system. That is, if you add up all the energy of an object(s) at one time it will equal all the energy of said object(s) at a later time. A closed system is a system where no energy is transferred in or out. The total energy of the universe is a constant (i. e. it does not change). The problems below do not consider the situation of energy transfer (called work). So friction and other sources where energy leaves the system are not present. Thus, one simply adds up all the potential energy and kinetic energy before and sets it equal to the addition of the total potential energy and kinetic energy after . Choices: - is replicated - is destroyed - is wasted - is conserved A:
is conserved
