Answer the following question given this paragraph: Neutron stars are the corpses of stars left over after supernova explosions. They are the size of a small city, but can spin several times per second. (Try to imagine this in your head. ) Consider a neutron star of radius 10 km that spins with a period of 0.8 seconds. Imagine a person is standing at the equator of this neutron star. Calculate the centripetal acceleration of this person and compare it to the acceleration due to gravity on Earth. Q: Neutron stars are the corpses of left over what? Choices: - planet explosions - gravitational explosions - stellar explosions - supernova explosions A:
supernova explosions
Q: Answer the following question given this paragraph: When a fluorine atom gains an electron, it becomes a negative fluoride ion. Q: When a fluorine atom gains an electron, it becomes a negative what? Choices: - hydrogen ion - sulfide ion - potassium ion - fluoride ion A:
A: fluoride ion
Question: Answer the following question given this paragraph: Milk and other dairy foods are not the only sources of calcium. This important nutrient is also found in green leafy vegetables, broccoli, and intact salmon and canned sardines with their soft bones. Nuts, beans, seeds, and shellfish provide calcium in smaller quantities. Except for fatty fish like salmon and tuna, or fortified milk or cereal, vitamin D is not found naturally in many foods. The action of sunlight on the skin triggers the body to produce its own vitamin D (Figure 6.22), but many people, especially those of darker complexion and those living in northern latitudes where the sun's rays are not as strong, are deficient in vitamin D. In cases of deficiency, a doctor can prescribe a vitamin D supplement. Q: The action of sunlight on the skin triggers the body to produce what vitamin? Choices: - Vitamin A - metabolic d - tissue d - vitamin d A:
Answer: vitamin d
*Question*
Answer the following question given this paragraph: Lipids are biochemical compounds such as fats and oils. They consist of fatty acids, which may saturated or unsaturated. Lipids are used to store energy. They also make up cell membranes. Q: What are biochemical compounds, such as fats and oils, that consist of fatty acids and store energy? Choices: - proteins - oils - tissues - lipids A:
**Answer**
lipids
Q: Answer the following question given this paragraph: Scientists create models with computers. Computers can handle enormous amounts of data. This can more accurately represent the real situation. For example, Earth's climate depends on an enormous number of factors. Climate models can predict how climate will change as certain gases are added to the atmosphere. To test how good a model is, scientists might start a test run at a time in the past. If the model can predict the present it is probably a good model. It is more likely to be accurate when predicting the future. Q: What technology do scientists use to create models? Choices: - calculators - patterns - microscopes - computers A:
A: computers
