Answer the following question given this paragraph: Today, remote-control vehicles, called remotely operated vehicles (ROVs) go to the deepest ocean floor. They don't have any people on board. However, they carry devices that record many measurements. They also collect sediments and take photos. Q: What type of vehicles is able to go to the deepest ocean floor? Choices: - off road vehicles - all-terrain vehicles - autonomous controlled airplanes - remote-control vehicles A:
remote-control vehicles
Answer the following question given this paragraph: treat genetic disorders. For example, copies of a normal gene might be inserted into a patient with a defective gene. This is called gene therapy . Ideally, it can cure a genetic disorder. Q: Inserting copies of normal genes into a patient with defective genes is known as? Choices: - pattern therapy - cloning - chromosome treatment - gene therapy A:
gene therapy

A: outer
Question: Answer the following question given this paragraph: The nitrogen atom of a primary amine is bonded to two hydrogen atoms and one carbon. The nitrogen atom of a secondary amine is bonded to one hydrogen and two carbons. The nitrogen atom of a tertiary amine is bonded to three carbon atoms. Amines are typically named by a common system rather than by IUPAC guidelines. The common system for naming amines along with several examples is shown below. Q: How many hydrogen atoms does a nitrogen atom of a primary amine have? Choices: - four - six - ten - two A:
Answer: two

Answer the following question given this paragraph: 8.4 Elastic Collisions in One Dimension Let us consider various types of two-object collisions. These collisions are the easiest to analyze, and they illustrate many of the physical principles involved in collisions. The conservation of momentum principle is very useful here, and it can be used whenever the net external force on a system is zero. We start with the elastic collision of two objects moving along the same linea one-dimensional problem. An elastic collision is one that also conserves internal kinetic energy. Internal kinetic energy is the sum of the kinetic energies of the objects in the system. Figure 8.6 illustrates an elastic collision in which internal kinetic energy and momentum are conserved. Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elasticsome kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. One macroscopic collision that is nearly elastic is that of two steel blocks on ice. Another nearly elastic collision is that between two carts with spring bumpers on an air track. Icy surfaces and air tracks are nearly frictionless, more readily allowing nearly elastic collisions on them. Elastic Collision An elastic collision is one that conserves internal kinetic energy. Internal Kinetic Energy Internal kinetic energy is the sum of the kinetic energies of the objects in the system. Q: An elastic collision is one that conserves internal energy of what type? Choices: - thermal - seismic - potential - kinetic A:
(Answer)
kinetic
