Q: Why do players with more mass often have a larger impact in football? Read this paragraph and choose the correct option from the provided answers: Figure 28.18 Momentum is an important concept for these football players from the University of California at Berkeley and the University of California at Davis. Players with more mass often have a larger impact because their momentum is larger. For objects moving at relativistic speeds, the effect is even greater. (credit: John Martinez Pavliga). Choices: - potential energy is lower - kinetic energy is lower - Velocity is larger - momentum is larger A:
(Answer)
momentum is larger

Ques: Q: Animals that do not have internal control of their body temperature are called what? Read this paragraph and choose the correct option from the provided answers: Thermoregulation Animals can be divided into two groups: those that maintain a constant body temperature in the face of differing environmental temperatures, and those that have a body temperature that is the same as their environment and thus varies with the environmental temperature. Animals that do not have internal control of their body temperature are called ectotherms. The body temperature of these organisms is generally similar to the temperature of the environment, although the individual organisms may do things that keep their bodies slightly below or above the environmental temperature. This can include burrowing underground on a hot day or resting in the sunlight on a cold day. The ectotherms have been called cold-blooded, a term that may not apply to an animal in the desert with a very warm body temperature. An animal that maintains a constant body temperature in the face of environmental changes is called an endotherm. These animals are able to maintain a level of activity that an ectothermic animal cannot because they generate internal heat that keeps their cellular processes operating optimally even when the environment is cold. Choices: - athermal - photophores - cold-blooded - ectotherms A:
Ans: ectotherms

Q: When fuel is burned, most of the energy is released in what form? Read this paragraph and choose the correct option from the provided answers: When fuel is burned, most of the energy is released as heat. Some of this heat can be used to do work. Heat cooks food or warms your house. Sometimes the heat is just waste heat. It still heats the environment, though. Choices: - precipitation - carbon dioxide - humidity - heat A:

Ques:Q: When blood vessels in the head dilate, what kind of severe headache can occur? Read this paragraph and choose the correct option from the provided answers: A migraine is a more severe type of headache. It occurs when blood vessels in the head dilate, or expand. This may be triggered by certain foods, bright lights, weather changes, or other factors. People with migraines may also have nausea or other symptoms. Fortunately, migraines can often be relieved with prescription drugs. Choices: - malignant - chronic headache - tension headache - migraine A:

Ans:migraine

Ques: Q: A globe is the best way to make a map of what? Read this paragraph and choose the correct option from the provided answers: Earth is a sphere and so is a globe. A globe is the best way to make a map of the whole Earth. Because both the planet and a globe have curved surfaces, the sizes and shapes of countries are not distorted. Distances are true to scale. ( Figure below ). Choices: - a continent - solar system - a city - whole earth A:
Ans:
whole earth
