Answer the following question given this paragraph: 27.5 Single Slit Diffraction Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings. Figure 27.21 shows a single slit diffraction pattern. Note that the central maximum is larger than those on either side, and that the intensity decreases rapidly on either side. In contrast, a diffraction grating produces evenly spaced lines that dim slowly on either side of center. Q: What kind of lines does a diffraction grating produce? Choices: - nearly spaced lines - properly spaced lines - randomly spaced lines - evenly spaced lines A:
evenly spaced lines

Answer the following question given this paragraph: Nuclear energy is produced by carefully controlling the speed of a fission reaction. Q: Carefully controlling the speed of a fission reaction produces what kind of energy? Choices: - chemical - atomic - thermal - nuclear A:
nuclear

Answer the following question given this paragraph: Starch is a large, complex carbohydrate made of thousands of glucose units (monomers) joined together. Starches are found in foods such as vegetables and grains. Starches are broken down by the body into sugars that provide energy. Breads and pasta are good sources of complex carbohydrates. Q: Starch is a large, complex carbohydrate made of thousands of _____ joined together? Choices: - glucose partitions ( monomers ) - glucose orders ( monomers ) - glucose divisions ( monomers ) - glucose units (monomers) A:
glucose units (monomers)
