Answer the following question given this paragraph: Gravity has traditionally been defined as a force of attraction between things that have mass. According to this conception of gravity, anything that has mass, no matter how small, exerts gravity on other matter. Gravity can act between objects that are not even touching. In fact, gravity can act over very long distances. However, the farther two objects are from each other, the weaker is the force of gravity between them. Less massive objects also have less gravity than more massive objects. Q: What is the term for the force of attraction between things that have a mass? Choices: - weight - motion - magnetism - gravity A:
gravity
Answer the following question given this paragraph: Contour lines are lines of equal elevation. Contour intervals are the difference in elevation between two contour lines. Q: What is the term for the difference in elevation between two contour lines? Choices: - height - design interval - mapping interval - contour interval A:
contour interval
Q: Answer the following question given this paragraph: A hydrocarbon is an organic compound that is made up of only carbon and hydrogen. A hydrocarbon is the simplest kind of organic molecule and is the basis for all other more complex organic compounds. Hydrocarbons can be divided into two broad categories. Aliphatic hydrocarbons are hydrocarbons that do not contain the benzene group or a benzene ring . Aromatic hydrocarbons contain one or more benzene rings. In this concept, we will discuss the aliphatic hydrocarbons. Q: What is an organic compound that is made up of only carbon and hydrogen? Choices: - an acid - a catalyst - a component - a hydrocarbon A:
A: a hydrocarbon
Question: Answer the following question given this paragraph: Electric current is a continuous flow of electric charge. It is measured in amperes (A). Direct current (DC) flows in just one direction. Alternating current (AC) keeps reversing direction. Q: What is a continuous flow of electric charge called? Choices: - powered current - microwave current - magnetism - electric current A:
Answer: electric current

Answer the following question given this paragraph: To balance a nuclear reaction. The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements. The resulting daughter nuclei have a lower mass and are lower in energy (more stable) than the parent nucleus that decayed. In contrast, in anuclear transmutation reaction, a nucleus reacts with a subatomic particle or another nucleus to form a product nucleus that is more massive than the. Q: When an unstable nucleus emits radiation and is transformed into the nucleus of other elements this is called? Choices: - naturally decay - explosive decay - fusion decay - radioactive decay A:
**Answer**
radioactive decay

Answer the following question given this paragraph: Of the three basic types of emissions, gamma radiation has the highest penetrating power. Thick, high density materials (such as lead) are required to stop gamma emissions. The thickness of the shielding will determine the effectiveness of the protection offered by the lead. Q: Of the three basic types of emissions, which has the highest penetrating power? Choices: - ultraviolet radiation - fluid radiation - chemical radiation - gamma radiation A:
**Answer**
gamma radiation
