Answer the following question given this paragraph: Many meteorites are remnants of the earliest material that formed in the solar system. Q: What astronomical phenomenon is often comprised of remnants of the earliest material that formed in the solar system? Choices: - asteroids - particles - comets - meteorites A:
meteorites

Answer the following question given this paragraph: Uranus is faint because it is very far away. Its distance from the Sun is 2.8 billion kilometers (1.8 billion miles). A photon from the Sun takes about 2 hours and 40 minutes to reach Uranus. Uranus orbits the Sun once about every 84 Earth years. Q: Why is uranus so faint? Choices: - polluted atmosphere - too small - too cold - far away A:
(Answer)
far away
Ques: Answer the following question given this paragraph: Fission is a type of radioactivity in which large nuclei spontaneously break apart into smaller nuclei. Q: Fission is a type of radioactivity in which large nuclei spontaneously break apart into what? Choices: - faster nuclei - light nuclei - active nuclei - smaller nuclei A:
Ans: smaller nuclei
(Q).
Answer the following question given this paragraph: A superheated liquid exists temporarily as liquid with a temperature above the normal boiling point of the liquid. When a supercooled liquid boils, the temperature drops as the liquid is converted to vapor. Conversely, a supercooled liquid exists temporarily as a liquid with a temperature lower than the normal melting point of the solid. As shown below, when a supercooled liquid crystallizes, the temperature increases as the liquid is converted to a solid. Q: When a supercooled liquid boils, the temperature drops as the liquid is converted to what? Choices: - carbon - solid - atoms - vapor A:
(A).
vapor
Ques:Answer the following question given this paragraph: Measurement of exposure to radioactivity is important for anyone who deals with radioactive materials on a regular basis. Perhaps the simplest device is a personal dosimeter a film badge that will fog up when exposed to radiation. The amount of fogging is proportional to the amount of radiation present. These devices are not very sensitive to low levels of radiation. More sensitive systems use crystals that respond in some way to radioactivity by registering the number of emissions in a given time. These systems tend to be more sensitive and more reliable than film badges. Q: What is used by sensitive systems to detect even low levels of radiation? Choices: - electrons - radars - ions - crystals A:

Ans:crystals
Question: Answer the following question given this paragraph: The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. Ironically, the deadly effects of gamma rays can be used to treat cancer. In this type of treatment, a medical device sends out focused gamma rays that target cancerous cells. The gamma rays kill the cells and destroy the cancer. Q: What enables gamma rays to pass through hard matters like bones, teeth, and just about anything? Choices: - Weight - Being Heavier - Density - their extremely high energy A:
Answer:
their extremely high energy
