Answer the following question given this paragraph: Archimedes' law explains why some objects float in fluids even though they are very heavy. It all depends on how much fluid they displace. The cruise ship pictured in the opening image is extremely heavy, yet it stays afloat. If a steel ball with the same weight as the ship were placed in water, it would sink to the bottom. This is modeled in the Figure below . The reason the ball sinks is that its shape is very compact, so it displaces relatively little water. The volume of water displaced by the steel ball weighs less than the ball itself, so the buoyant force is not as great as the force of gravity pulling down on the ball. Thus, the ball sinks. Q: What law explains why some objects float and some sink. Choices: - newton's law - montenegrins ' law - flanges ' law - archimedes' law A:
(Answer)
archimedes' law
Ques: Answer the following question given this paragraph: Monatomic ions form when a single atom gains or loses electrons. For the main group elements, cations are generally formed by removing all of the valence electrons from the atom. Since the numbers of valence electrons for the representative elements are constant within a particular group, all we need is the group number of a given element to know its charge when it becomes a cation. Group 1 elements form ions with a 1+ charge, Group 2 metal ions have a 2+ charge, and the ions of Group 13 elements tend to have a 3+ charge. Heavier p-block metals such as tin and lead are special cases and will be discussed with the transition metal ions. The name of a monatomic cation is the same as the name of the neutral element. For example, the sodium atom (Na) loses a single electron to form the sodium ion (Na + ), while Al 3+ is an aluminum ion. Q: What form when a single atom gains or loses electrons? Choices: - fusional ions - vacuoles ions - carbon atoms - monatomic ions A:
Ans: monatomic ions

Answer the following question given this paragraph: Flaps of tissue called valves separate the heart's chambers. Valves keep blood flowing in just one direction through the heart. For example, a valve at the bottom of the right atrium opens to let blood flow from the right atrium to the right ventricle. Then the valve closes so the blood can't flow back into the right atrium. Q: What is the largest artery in the body called? Choices: - ventricular - carotid - radial - aorta A:
(A).
aorta
