Answer the following question given this paragraph: When you use a machine, you apply force to the machine. This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force. The output force may or may not be the same as the input force. The force you apply to the machine is applied over a given distance, called the input distance. The force applied by the machine to the object is also applied over a distance, called the output distance. The output distance may or may not be the same as the input distance. Q: What do you call the force a machine applies to an object? Choices: - premium force - drop force - optimal force - output force A:
output force

Answer the following question given this paragraph: Metalloids are the smallest class of elements. (The other two classes of elements are metals and nonmetals). There are just six metalloids. In addition to silicon, they include boron, germanium, arsenic, antimony, and tellurium. Metalloids fall between metals and nonmetals in the periodic table. They also fall between metals and nonmetals in terms of their properties. Q: Metalloids, metals, and nonmetals are all classes of what? Choices: - compounds - protons - matter - elements A:
(Answer)
elements

The closer together the particles are, the greater the amplitude. Q: In a longitudinal wave, what term is a measure of how compressed particles of the medium become when the wave passes through? Choices: - magnitude - frequency - voltage - amplitude A:
Ans: amplitude

Ques:Answer the following question given this paragraph: Bacterial contamination of foods can lead to digestive problems, an illness known as food poisoning . Raw eggs and undercooked meats commonly carry the bacteria that can cause food poisoning. Food poisoning can be prevented by cooking meat thoroughly and washing surfaces that have been in contact with raw meat. Washing your hands before and after handling food also helps prevent contamination. Q: Bacterial contamination of foods can lead to digestive problems called what? Choices: - cancer - the flu - butterflies in your stomach - food poisoning A:

Ans:food poisoning
Answer the following question given this paragraph: Migration Migration is the long-range seasonal movement of animals. It is an evolved, adapted response to variation in resource availability, and it is a common phenomenon found in all major groups of animals. Birds fly south for the winter to get to warmer climates with sufficient food, and salmon migrate to their spawning grounds. The popular 2005 documentary March of the Penguins followed the 62-mile migration of emperor penguins through Antarctica to bring food back to their breeding site and to their young. Wildebeests (Figure 45.35) migrate over 1800 miles each year in search of new grasslands. Q: What evolved, adapted response to resource availability is the long-range seasonal movement of animals? Choices: - changing - Stagnation - regulating - migration A:
migration
