input: OPTIONS:
- elastic energy
- residual energy
- viscosity energy
- kinetic energy Now, answer this question: Answer the following question given this paragraph: The behavior of the atoms, molecules, or ions that comprise the reactants is responsible for the rates of a given chemical reaction. Collision theory is a set of principles that states that the reacting particles can form products when they collide with one another provided those collisions have enough kinetic energy and the correct orientation. Particles that lack the necessary kinetic energy may collide, but the particles will simply bounce off one another unchanged. The figure below illustrates the difference. In the first collision, the particles bounce off one another and no rearrangement of atoms has occurred. The second collision occurs with greater kinetic energy, and so the bond between the two red atoms breaks. One red atom bonds with the other molecule as one product, while the single red atom is the other product. The first collision is called an ineffective collision , while the second collision is called an effective collision . Q: According to collision theory, particles that lack what kind of energy may collide, but the particles will simply bounce off one another unchanged? A:
A:
output: kinetic energy

Q: Answer the following question given this paragraph: Introduction to Particle Physics Following ideas remarkably similar to those of the ancient Greeks, we continue to look for smaller and smaller structures in nature, hoping ultimately to find and understand the most fundamental building blocks that exist. Atomic physics deals with the smallest units of elements and compounds. In its study, we have found a relatively small number of atoms with systematic properties that explained a tremendous range of phenomena. Nuclear physics is concerned with the nuclei of atoms and their substructures. Here, a smaller number of componentsthe proton and neutronmake up all nuclei. Exploring the systematic behavior of their interactions has revealed even more about matter, forces, and energy. Particle physics deals with the substructures of atoms and nuclei and is particularly aimed at finding those truly fundamental particles that have no further substructure. Just as in atomic and nuclear physics, we have found a complex array of particles and properties with systematic characteristics analogous to the periodic table and the chart of nuclides. An underlying structure is apparent, and there is some reason to think that we are finding particles that have no substructure. Of course, we have been in similar situations before. For example, atoms were once thought to be the ultimate substructure. Perhaps we will find deeper and deeper structures and never come to an ultimate substructure. We may never really know, as indicated in Figure 33.2. Q: What branch of physics deals with the smallest units of elements and compounds? A:
Answer: atomic

Problem:OPTIONS:
- core
- neutron
- nucleus
- atom

Answer the following question given this paragraph: The smallest particle of an element that still has the properties of that element is the atom . Atoms actually consist of smaller particles, including protons and electrons, but these smaller particles are the same for all elements. All the atoms of an element are like one another, and are different from the atoms of all other elements. For example, the atoms of each element have a unique number of protons. Q: What is the smallest part of an element called? A:
****
A: atom

Answer the following question given this paragraph: 28.2 Simultaneity And Time Dilation Two events are defined to be simultaneous if an observer measures them as occurring at the same time. They are not necessarily simultaneous to all observerssimultaneity is not absolute. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Observers moving at a relative velocity v do not measure the same elapsed time for an event. Proper time t 0 is the time measured by an observer at rest relative to the event being observed. Proper time is related to the time by an Earth-bound observer by the equation. Q: Two events are defined to be simultaneous if an observer measures them as occurring at what? A:
OPTIONS:
- midnight
- opposite times
- different times
- same time
same time

Answer the following question given this paragraph: Platelets ( Figure below ) are very small, but they are very important in blood clotting. Platelets are not cells. They are sticky little pieces of larger cells. Platelets bud off large cells that stay in the bone marrow. When a blood vessel gets cut, platelets stick to the injured areas. They release chemicals called clotting factors, which cause proteins to form over the wound. This web of proteins catches red blood cells and forms a clot. This clot stops more blood from leaving the body through the cut blood vessel. The clot also stops bacteria from entering the body. Platelets survive in the blood for ten days before they are removed by the liver and spleen. Q: What part of blood releases clotting factors? A:
OPTIONS:
- hemoglobin
- white blood cells
- erythrocytes
- platelets

Answer:
platelets
