Q: Gas particles are constantly colliding with each other and the walls of a container, and these collisions are elastic, so there is no net loss of what? Read this paragraph and choose the correct option from the provided answers: A N SW E R S 1. Gases consist of tiny particles of matter that are in constant motion. Gas particles are constantly colliding with each other and the walls of a container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are separated by large distances, with the size of a gas particle tiny compared to the distances that separate them. There are no interactive forces (i. , attraction or repulsion) between the particles of a gas. The average speed of gas particles is dependent on the temperature of the gas. Choices: - velocity - heat - temperature - energy A:
**Answer**
energy

Q: Life probably began where? Read this paragraph and choose the correct option from the provided answers: Life probably began in the oceans. No one knows exactly how or when. Life may have originated more than once. If life began before the Moon formed, that impact would have wiped it out. Then life would have had to originate again. Eventually conditions on Earth became less violent. The planet could support life. Choices: - rocks - the Sun - caves - oceans A:
**Answer**
oceans

Q: Colliding-beam accelerators create matter from what? Read this paragraph and choose the correct option from the provided answers: Conceptual Questions 33.3 Accelerators Create Matter from Energy 1. The total energy in the beam of an accelerator is far greater than the energy of the individual beam particles. Why isn't this total energy available to create a single extremely massive particle? 2. Synchrotron radiation takes energy from an accelerator beam and is related to acceleration. Why would you expect the problem to be more severe for electron accelerators than proton accelerators? 3. What two major limitations prevent us from building high-energy accelerators that are physically small? 4. What are the advantages of colliding-beam accelerators? What are the disadvantages?. Choices: - magnetism - sound - minerals - energy A:
**Answer**
energy

Q: The collision of what is responsible for massive earthquakes? Read this paragraph and choose the correct option from the provided answers: The collision of two continents also creates massive earthquakes. Many earthquakes happen in the region in and around the Himalayan Mountains. The 2001 Gujarat, India earthquake is responsible for about 20,000 deaths, with many more people injured or made homeless ( Figure below ). Choices: - weather fronts - tidal currents - fault lines - two continents A:
**Answer**
two continents
