Answer the following question given this paragraph: Pendulums are in common usage. Some have crucial uses, such as in clocks; some are for fun, such as a child's swing; and some are just there, such as the sinker on a fishing line. For small displacements, a pendulum is a simple harmonic oscillator. A simple pendulum is defined to have an object that has a small mass, also known as the pendulum bob, which is suspended from a light wire or string, such as shown in Figure 16.14. Exploring the simple pendulum a bit further, we can discover the conditions under which it performs simple harmonic motion, and we can derive an interesting expression for its period. Q: What is the common name for a simple harmonic oscillator, which basically consists of a small object suspended on a wire or string? Choices: - yo-yo - metronome - pendant - pendulum A:
pendulum

Answer the following question given this paragraph: Q: Chloroplasts are present only in cells of eukaryotes capable of what process? Choices: - hydrolysis - digestion - sexual reproduction - photosynthesis A:
(Answer)
photosynthesis
Ques: Answer the following question given this paragraph: The acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter (Figure 14.4). Q: The acidity of a solution is typically assessed experimentally by measurement of its what? Choices: - mass - density - color - ph A:
Ans: ph
(Q).
Answer the following question given this paragraph: Water is an example of a common chemical compound. As you can see in the Figure below , each water molecule consists of two atoms of hydrogen and one atom of oxygen. Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition. Q: What molecule consists of two atoms of hydrogen and one atom of oxygen? Choices: - carbon monoxide - hydrogen peroxide - air - water A:
(A).
water
Ques:Answer the following question given this paragraph: Ocean waves are energy traveling through water. They are caused mainly by wind blowing over the water. Q: What are ocean waves mainly caused by? Choices: - tides - gravity - humidity - wind A:

Ans:wind
Question: Answer the following question given this paragraph: thrombosis, can be caused by excessive numbers of platelets. A thrombus is a collection of fibrin, platelets, and erythrocytes that has accumulated along the lining of a blood vessel, whereas an embolus is a thrombus that has broken free from the vessel wall and is circulating in the bloodstream. Q: What is a collection of fibrin, platelets, and erythrocytes that has accumulated along the lining of a blood vessel called? Choices: - atherosclerosis - embolus - clots - thrombus A:
Answer:
thrombus
