Answer the following question given this paragraph: The system is isolated from other masses. This allows us to neglect any small effects due to outside masses. The conditions are satisfied, to good approximation, by Earth's satellites (including the Moon), by objects orbiting the Sun, and by the satellites of other planets. Historically, planets were studied first, and there is a classical set of three laws, called Kepler's laws of planetary motion, that describe the orbits of all bodies satisfying the two previous conditions (not just planets in our solar system). These descriptive laws are named for the German astronomer Johannes Kepler (15711630), who devised them after careful study (over some 20 years) of a large amount of meticulously recorded observations of planetary motion done by Tycho Brahe (15461601). Such careful collection and detailed recording of methods and data are hallmarks of good science. Data constitute the evidence from which new interpretations and meanings can be constructed. Q: Kepler's laws relate to the motion of what? Choices: - continents - oceans - the sun - planets A:
planets

Answer the following question given this paragraph: For molecules with more than two atoms, the molecular geometry must also be taken into account when determining if the molecule is polar or nonpolar. The Figure below shows a comparison between carbon dioxide and water. Carbon dioxide (CO 2 ) is a linear molecule. The oxygen atoms are more electronegative than the carbon atom, so there are two individual dipoles pointing outward from the C atom to each O atom. However, since the dipoles are of equal strength and are oriented in this way, they cancel each other out and the overall molecular polarity of CO 2 is zero. Q: What type of molecule is carbon dioxide (co2)? Choices: - non-linear - planar - filter - linear A:
(Answer)
linear
Ques: Answer the following question given this paragraph: Figure 12.7 Statues made from carbonate compounds such as limestone and marble typically weather slowly over time due to the actions of water, and thermal expansion and contraction. However, pollutants like sulfur dioxide can accelerate weathering. As the concentration of air pollutants increases, deterioration of limestone occurs more rapidly. (credit: James P Fisher III). Q: Deterioration of limestone occurs more rapidly as the concentration of what increases? Choices: - ground pollutants - water pollutants - ocean pollutants - air pollutants A:
Ans: air pollutants
