Answer the following question given this paragraph: This equation for kinetic energy shows that velocity affects kinetic energy more than mass does. For example, if mass doubles, kinetic energy also doubles. But if velocity doubles, kinetic energy increases by a factor of four. That's because velocity is squared in the equation. You can see for yourself how mass and velocity affect kinetic energy by working through the problems below. Q: Velocity affects what type of energy more than mass does? Choices: - magnetic energy - harmonic energy - mechanical energy - kinetic energy A:
kinetic energy

Answer the following question given this paragraph: Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force. For orbiting satellites, such as the moon orbiting the earth or the earth orbiting the sun, the centripetal force is produced by gravity. When an Olympic hammer thrower whirls a massive ball on a chain, the centripetal force is created by the athlete and transmitted by the chain. Q: What produces the centripetal force to keep the earth orbiting the sun? Choices: - heat - motion - weight - gravity A:
(Answer)
gravity
Ques: Answer the following question given this paragraph: Viruses , like the one depicted in Figure below , are tiny particles that may cause disease. Human diseases caused by viruses include the common cold and flu. Do you think viruses are prokaryotes or eukaryotes? The answer may surprise you. Viruses are not cells at all, so they are neither prokaryotes nor eukaryotes. Q: The common cold and flu are examples of human diseases caused by what tiny particles? Choices: - infections - parasites - bacteria - viruses A:
Ans: viruses
(Q).
Answer the following question given this paragraph: Average global temperature has risen since 1900. Q: What has the average global temperature done since the 1900s? Choices: - stayed constant - changed randomly - decreased - risen A:
(A).
risen
Ques:Answer the following question given this paragraph: Vertebrates have one of three reproductive strategies, known as ovipary, ovovivipary, or vivipary. Q: In vertebrates, ovipary, ovovivipary, and vivipary are different strategies for what vital process? Choices: - respiration - absorption - circulation - reproduction A:

Ans:reproduction
Answer the following question given this paragraph: Neural Control of Thermoregulation The nervous system is important to thermoregulation, as illustrated in Figure 33.22. The processes of homeostasis and temperature control are centered in the hypothalamus of the advanced animal brain. Q: The processes of homeostasis and temperature control are centered in the hypothalamus of the advanced animal brain, thus thermoregulation depends on what organ system? Choices: - circulatory system - digestive system - cardiovascular system - nervous system A:
nervous system
