Answer the following question given this paragraph: Electrons are negatively charged particles in atoms. Moving electrons have a form of kinetic energy called electrical energy . If you've ever experienced an electric outage, then you know how hard it is to get by without electrical energy. Most of the electrical energy we use is produced by power plants and arrives in our homes through wires. Two other sources of electrical energy are pictured in Figure below . Q: Moving electrons have a form of kinetic energy called what? Choices: - potential energy - electromagnetism - deformed energy - electrical energy A:
(Answer)
electrical energy
Ques: Answer the following question given this paragraph: Amphibians! In order for water-dwelling animals to adapt to life on land, many new adaptations had to take place. First, they needed to be able to breathe air instead of obtaining oxygen from water. And fins don't work well as legs! They needed to be able to move around well on land. Q: What broad category of animals shows adaptations from water-dwelling to land-dweller, including the ability to breathe air and legs to move on land? Choices: - reptiles - birds - herbivores - amphibians A:
Ans: amphibians
(Q).
Answer the following question given this paragraph: When electrons are removed from an atom, that process requires energy to pull the electron away from the nucleus. Addition of an electron releases energy from the process. Q: What is required when electrons are removed from an atom, and released from the process when an electron is added? Choices: - nuclear - proton - fuel - energy A:
(A).
energy
Ques:Answer the following question given this paragraph: Radiation fog forms at night. Skies are clear, and the relative humidity is high. The ground cools as temperature goes down. Air near the ground cools below its dew point. Tule fog is an extreme form of radiation fog. This type of fog strikes the Central Valley of California in winter. Q: What is the name of an extreme form of radiation fog? Choices: - smelt fog - aura fog - cedar fog - tule fog A:

Ans:tule fog
Question: Answer the following question given this paragraph: There are several other examples of objects that increase their rate of spin because something reduced their moment of inertia. Tornadoes are one example. Storm systems that create tornadoes are slowly rotating. When the radius of rotation narrows, even in a local region, angular velocity increases, sometimes to the furious level of a tornado. Earth is another example. Our planet was born from a huge cloud of gas and dust, the rotation of which came from turbulence in an even larger cloud. Gravitational forces caused the cloud to contract, and the rotation rate increased as a result. (See Figure 10.24. Q: What is said about the speed of rotation in systems that create tornadoes? Choices: - it is magnetic - it is unchanged - it is fast - it is slow A:
Answer:
it is slow
