Answer the following question given this paragraph: The angular velocity tells you how quickly the angle changes. In more formal language, the rate of change of , the angular position, is called the angular velocity . The direction of angular velocity is either clockwise or counterclockwise. Analogously, the rate of change of is the angular acceleration . Q: What term tells you how quickly the angle changes and can occur in either clockwise or counterclockwise directions? Choices: - emit velocity - shift velocity - turning velocity - angular velocity A:
(Answer)
angular velocity
Ques: Answer the following question given this paragraph: Hearing loss caused by loud sounds is permanent. However, this type of hearing loss can be prevented by protecting the ears from loud sounds. Q: What do the ears have to be protected from in order to avoid hearing loss? Choices: - Cold weather - Water - Storms - loud sounds A:
Ans: loud sounds
(Q).
Answer the following question given this paragraph: When Earth first formed, it was a fiery hot, barren ball. It had no oceans or atmosphere. Rivers of melted rock flowed over its surface. Gradually, the planet cooled and formed a solid crust. Gases from volcanoes formed an atmosphere, although it contained only a trace of oxygen. As the planet continued to cool, clouds formed and rain fell. Rainwater helped form oceans. The ancient atmosphere and oceans would be toxic to modern life, but they set the stage for life to begin. Q: What did volcanic gases help to form on earth? Choices: - water - plants - rocks - atmosphere A:
(A).
atmosphere
Ques:Answer the following question given this paragraph: Every surface has microscopic bumps, lumps, and imperfections, emphasized as in the image above. If we try to slide the top block over the lower block, there will be numerous collisions as the bumps impact each other. The forward motion causes the collisions with bumps which then exert a force in opposite way the block is moving. The force of friction always opposes whatever motion is causing the friction. Q: What force is caused by microscopic bumps, lumps, and imperfections colliding? Choices: - gravitational - motion - tension - friction A:

Ans:friction
Answer the following question given this paragraph: Fatty Acids. Saturated fatty acids have straight chains, like the three fatty acids shown on the left. Unsaturated fatty acids have bent chains, like all the other fatty acids in the figure. Q: What type of fatty acids have bent chains? Choices: - cholesterol - saturated fatty acids - lipids - unsaturated fatty acids A:
unsaturated fatty acids
