Answer the following question given this paragraph: An atom's protons and electrons carry electrical charges. Protons, with their positive charge, are designated p+. Electrons, which have a negative charge, are designated e. An atom's neutrons have no charge: they are electrically neutral. Just as a magnet sticks to a steel refrigerator because their opposite charges attract, the positively charged protons attract the negatively charged electrons. This mutual attraction gives the atom some structural stability. The attraction by the positively charged nucleus helps keep electrons from straying far. The number of protons and electrons within a neutral atom are equal, thus, the atom's overall charge is balanced. Q: What part of an atom is electrically neutral? Choices: - protons - electrons - newtons - neutrons A:
neutrons

Answer the following question given this paragraph: 7. You look through a telescope at Rigel. Rigel is the brightest star in the Orion constellation. Rigel is around 800 light years from Earth. What are you looking at when you look through that telescope? What does Rigel look like today?. Q: What is the brightest star in the orion constellation? Choices: - natel - omicron - sol - rigel A:
(Answer)
rigel
Ques: Answer the following question given this paragraph: of pivot point, and so we choose the pivot point to simplify the solution of the problem. Second, the acceleration due to gravity canceled in this problem, and we were left with a ratio of masses. This will not always be the case. Always enter the correct forcesdo not jump ahead to enter some ratio of masses. Third, the weight of each child is distributed over an area of the seesaw, yet we treated the weights as if each force were exerted at a single point. This is not an approximationthe distances r 1 and r 2 are the distances to points directly below the center of gravity of each child. As we shall see in the next section, the mass and weight of a system can act as if they are located at a single point. Finally, note that the concept of torque has an importance beyond static equilibrium. Torque plays the same role in rotational motion that force plays in linear motion. We will examine this in the next chapter. Take-Home Experiment Take a piece of modeling clay and put it on a table, then mash a cylinder down into it so that a ruler can balance on the round side of the cylinder while everything remains still. Put a penny 8 cm away from the pivot. Where would you need to put two pennies to balance? Three pennies?. Q: What plays the same role in rotational motion that force plays in linear motion. Choices: - efficiency - frame - fulcrum - torque A:
Ans: torque

Answer the following question given this paragraph: Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis :. Q: Which process acts as a natural complement for cellular respiration? Choices: - glycolysis - atherosclerosis - absorption - photosynthesis A:
(A).
photosynthesis
