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:
far away

Answer the following question given this paragraph: Weather stations contain many instruments for measuring weather conditions. The weather balloon ( Figure above ) will rise into the atmosphere until it bursts. As it rises, it will gather weather data and send it to the surface. Many weather satellites orbit Earth. They constantly collect and transmit weather data from high above the surface. A radar device sends out radio waves in all directions. The waves bounce off water in the atmosphere and then return to the sender. The radar data shows where precipitation is falling. It's raining in the orange-shaded area shown above. Q: When do weather balloons return to earth? Choices: - when the air heats up - when the timer runs out - when the air cools - when it bursts A:
(Answer)
when it bursts

Pluto and its moon, Charon, are actually two objects . Public Domain. Q: Fungus-like protists are what kind of feeders? Choices: - demonstrative - refractive - reverse - absorptive A:
Ans: absorptive

Answer the following question given this paragraph: Next, we identify the least precise measurement: 13.7 kg. This measurement is expressed to the 0.1 decimal place, so our final answer must also be expressed to the 0.1 decimal place. Thus, the answer is rounded to the tenths place, giving us 15.2 kg. Significant Figures in this Text In this text, most numbers are assumed to have three significant figures. Furthermore, consistent numbers of significant figures are used in all worked examples. You will note that an answer given to three digits is based on input good to at least three digits, for example. If the input has fewer significant figures, the answer will also have fewer significant figures. Care is also taken that the number of significant figures is reasonable for the situation posed. In some topics, particularly in optics, more accurate numbers are needed and more than three significant figures will be used. Finally, if a number is exact, such as the two in the formula for the circumference of a circle, c = 2r , it does not affect the number of significant figures in a calculation. Q: What type of numerical figure is important in considering the precision and accuracy of a number? Choices: - component - insignificant - exponent - significant A:
(A).
significant
Ques:Answer the following question given this paragraph: This is a strombolian eruption. This type of eruption was named for Mt. Stromboli in Italy. Strombolian eruptions spew lava into the air. But these eruptions do not have a massive explosion. They create lava flows. Q: What is a strombolian eruption named for? Choices: - an ice cleaner - a country - mt. st. helens - mt. stromboli A:

Ans:mt. stromboli
