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. A:
OPTIONS:
- efficiency
- frame
- fulcrum
- torque
torque

Answer the following question given this paragraph: Scientists also collect rock and sediment samples from the seafloor. A dredge is a giant rectangular bucket that is dragged along behind a ship. The dredge picks up loose rocks lying on the seafloor. Gravity corers are metal tubes that fall to the seafloor. They slice into the sediments to collect a sample. The research vessel, the Joides Resolution , drills deep into the seafloor to collect samples of the sediment and ocean crust. Scientists analyze the samples for chemistry and their magnetic properties. Q: Behind a ship, what is the giant rectangular bucket that is dragged along from the behind called? A:
OPTIONS:
- prop
- trousers
- wig
- dredge

Answer: dredge

Question: Answer the following question given this paragraph: Sickle-Shaped and Normal Red Blood Cells. Sickle cell anemia is an autosomal recessive disorder. The mutation that causes the disorder affects just one amino acid in a single protein, but it has serious consequences for the affected person. This photo shows the sickle shape of red blood cells in people with sickle cell anemia. Q: Sickle cell anemia is what type of disorder? A:
OPTIONS:
- autosomal dominant disorder
- spontaneous mutation
- nongenetic disorder
- autosomal recessive disorder
Answer: autosomal recessive disorder

input with options: Answer the following question given this paragraph: Skin is made up of two layers, the epidermis on top and the dermis below. The tissue below the dermis is called the hypodermis, but it is not part of the skin. Q: What two layers is the skin made of? A:
OPTIONS:
- respiration and dermis
- layers and dermis
- Blood and dermis
- epidermis and dermis
output: epidermis and dermis

Q: Answer the following question given this paragraph: Even if Laura didn't try to stop the skateboard, it would stop sooner or later. That's because there's also friction between the wheels and the pavement. Friction is a force that counters all kinds of motion. It occurs whenever two surfaces come into contact. Q: What force occurs whenever two surfaces come into contact? A:

OPTIONS:
- tension
- vibration
- gravity
- friction

A: friction

Answer the following question given this paragraph: If only one atom of a specific type is present, no subscript is used. Q: If only one atom of a specific type is present what is not used? A:
OPTIONS:
- covalent bond
- consonant
- subset
- subscript
subscript
