Answer the following question given this paragraph: The force that a magnet exerts is called magnetic force. The force is exerted over a distance and includes forces of attraction and repulsion. A magnet can exert force over a distance because the magnet is surrounded by a magnetic field. Q: What force includes forces of attraction and repulsion? Choices: - centripetal force - gravitational force - molecular force - magnetic force A:
magnetic force

Answer the following question given this paragraph: Nuclear power is clean. It does not pollute the air. However, the use of nuclear energy does create other environmental problems. Uranium must be mined ( Figure below ). The process of splitting atoms creates radioactive waste. This waste may be dangerous for thousands or hundreds of thousands of years. As yet, there is no long-term solution for storing the radioactive waste. Q: The process of splitting atoms creates what kind of waste? Choices: - recyclable - inert - safe - radioactive A:
(A).
radioactive
