Ques: 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:
Ans: angular velocity

Ques: Answer the following question given this paragraph: The process in which a solid changes directly to a gas is called sublimation . It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO 2 ) is an example of a solid that undergoes sublimation. Figure below shows a chunk of dry ice changing directly to carbon dioxide gas. Sometimes snow undergoes sublimation as well. This is most likely to occur on sunny winter days when the air is very dry. What gas does snow become?. Q: What is the process in which a solid changes directly to a gas called? Choices: - condensation - solidification - vaporization - sublimation A:
Ans: sublimation

Ques: Answer the following question given this paragraph: The autonomic nervous system serves as the relay between the CNS and the internal organs. It controls the lungs, the heart, smooth muscle, and exocrine and endocrine glands. The autonomic nervous system controls these organs largely without conscious control; it can continuously monitor the conditions of these different systems and implement changes as needed. Signaling to the target tissue usually involves two synapses: a preganglionic neuron (originating in the CNS) synapses to a neuron in a ganglion that, in turn, synapses on the target organ (Figure 16.24). There are two divisions of the autonomic nervous system that often have opposing effects: the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system is responsible for the immediate responses an animal makes when it encounters a dangerous situation. One way to remember this is to think of the "fight-or-flight" response a person feels when encountering a snake ("snake" and "sympathetic" both begin with "s"). Examples of functions controlled by the sympathetic nervous system include an accelerated heart rate and inhibited digestion. These functions help prepare an organism's body for the physical strain required to escape a potentially dangerous situation or to fend off a predator. Q: The autonomic nervous system serves as the relay between what and the internal organs? Choices: - hormones - somatic system - peripheral nervous system - central nervous system A:
Ans: central nervous system

Ques: Answer the following question given this paragraph: A: With greater reflection off the ionosphere, AM waves can travel even farther at night than they can during the day. Radio receivers can often pick up radio broadcasts at night from cities that are hundreds of miles away. Q: Greater reflection off what atmospheric layer allows am radio waves to travel even farther at night than they can during the day? Choices: - stratosphere - exosphere - troposphere - ionosphere A:
Ans:
ionosphere
