Answer the following question given this paragraph: Introduction to Dynamics: Newton's Laws of Motion Motion draws our attention. Motion itself can be beautiful, causing us to marvel at the forces needed to achieve spectacular motion, such as that of a dolphin jumping out of the water, or a pole vaulter, or the flight of a bird, or the orbit of a satellite. The study of motion is kinematics, but kinematics only describes the way objects movetheir velocity and their acceleration. Dynamics considers the forces that affect the motion of moving objects and systems. Newton's laws of motion are the foundation of dynamics. These laws provide an example of the breadth and simplicity of principles under which nature functions. They are also universal laws in that they apply to similar situations on Earth as well as in space. Isaac Newton's (16421727) laws of motion were just one part of the monumental work that has made him legendary. The development of Newton's laws marks the transition from the Renaissance into the modern era. This transition was characterized by a revolutionary change in the way people thought about the physical universe. For many centuries natural philosophers had debated the nature of the universe based largely on certain rules of logic with great weight given to the thoughts of earlier classical philosophers such as Aristotle (384322 BC). Among the many great thinkers who contributed to this change were Newton and Galileo. Q: Whose laws of motion are the foundation of dynamics? Choices: - aristotle - einstein - bell - newton A:
newton
Answer the following question given this paragraph: Like bacteria, reproduction in archaea is asexual. Archaea can reproduce through binary fission , where a parent cell divides into two genetically identical daughter cells. Archaea can also reproduce asexually through budding and fragmentation, where pieces of the cell break off and form a new cell, also producing genetically identical organisms. Q: Pieces of the cell break off and form a new cell in what type of reproduction that produces genetically identical organisms? Choices: - Meiosis - Mitosis - Fusion - fragmentation A:
fragmentation
Q: Answer the following question given this paragraph: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. Q: Chlorine and bromine gases released into the atmosphere have helped damage what layer of the atmosphere? Choices: - stratospheric layer - carbon layer - polluted layer - ozone layer A:
A: ozone layer
Question: Answer the following question given this paragraph: Tropical climates are found at or near the Equator. Because warm air rises at the Equator, there is a lot of rain. Q: What kind of climates are found at or near the equator? Choices: - dry grasslands - tundra - arctic climates - tropical climates A:
Answer: tropical climates

Answer the following question given this paragraph: A flood occurs when so much water enters a stream or river that it overflows its banks. Flood waters from a river are shown in Figure below . Like this flood, many floods are caused by very heavy rains. Floods may also occur when deep snow melts quickly in the spring. Q: What occurs when so much water enters a stream or river that it overflows its banks or when deep snow melts very quickly in spring? Choices: - drought - avalanche - storm - flooding A:
**Answer**
flooding

Answer the following question given this paragraph: When using measuring devices, we often use a technique called calibration to increase the accuracy of our measurements. Calibration is a method of setting or correcting a measuring device by matching it to known measurement standards. To better understand calibration, we will look at the example of calibrating a thermometer. All thermometers are slightly different in their temperature readings. One way to calibrate a thermometer is by using the freezing point and boiling point of water ( Figure below ). If we know that water freezes at 0C and boils at 100C, we can calibrate our thermometer by measuring the temperature of ice water and of boiling water. We place the thermometer in ice water and wait for the thermometer liquid to reach a stable height, then place a mark at this height which represents 0C. Then we place the thermometer in boiling water, and after waiting for the thermometer liquid to reach a stable height, we place a mark at this height which represents 100C. We can then place 100 equally spaced divisions between our 0 and 100C marks to each represent 1C. Our thermometer has now been calibrated using the known values for the freezing point and boiling point of water, and can be used to measure temperatures of objects between 0 and 100C. Q: What is the method of setting or correcting a measuring device by matching it to known measurement standards called? Choices: - parallax - distortion - precision - calibration A:
(Answer)
calibration
