Answer the following question given this paragraph: Early Accelerators An early accelerator is a relatively simple, large-scale version of the electron gun. The Van de Graaff (named after the Dutch physicist), which you have likely seen in physics demonstrations, is a small version of the ones used for nuclear research since their invention for that purpose in 1932. For more, see Figure 33.7. These machines are electrostatic, creating potentials as great as 50 MV, and are used to accelerate a variety of nuclei for a range of experiments. Energies produced by Van de Graaffs are insufficient to produce new particles, but they have been instrumental in exploring several aspects of the nucleus. Another, equally famous, early accelerator is the cyclotron, invented in 1930 by the American physicist, E. Lawrence (19011958). For a visual representation with more detail, see Figure 33.8. Cyclotrons use fixed-frequency alternating electric fields to accelerate particles. The particles spiral outward in a magnetic field, making increasingly larger radius orbits during acceleration. This clever arrangement allows the successive addition of electric potential energy and so greater particle energies are possible than in a Van de Graaff. Lawrence was involved in many early discoveries and in the promotion of physics programs in American. Q: Named after the dutch physicist, the van de graaff is a type of what device used for nuclear research? A:
OPTIONS:
- radiation detector
- electromagnetic
- barometer
- accelerator
accelerator

Answer the following question given this paragraph: Water is essential to life because chemical reactions within cells take place in water. Most people can survive only a few days without consuming water to replace their water losses. How do you lose water?. Q: What type of compound is essential to life? A:
OPTIONS:
- carbon
- oxygen
- nitrogen
- water

Answer: water

Question: Answer the following question given this paragraph: Facial Bones of the Skull The facial bones of the skull form the upper and lower jaws, the nose, nasal cavity and nasal septum, and the orbit. The facial bones include 14 bones, with six paired bones and two unpaired bones. The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones. Although classified with the brain-case bones, the ethmoid bone also contributes to the nasal septum and the walls of the nasal cavity and orbit. Q: The paired bones of the skull are the palatine, zygomatic, nasal, lacrimal, inferior nasal conchae bones, and what else? A:
OPTIONS:
- minilla
- ventral
- elongated
- maxilla
Answer: maxilla

input with options: Answer the following question given this paragraph: The basic unit of matter is an atom ( Figure below ). At the center of an atom is its nucleus . Protons are positively charged particles in the nucleus. Also in the nucleus are neutrons with no electrical charge. Orbiting the nucleus are tiny electrons. Electrons are negatively charged. An atom with the same number of protons and electrons is electrically neutral. If the atom has more or less electrons to protons it is called an ion . An ion will have positive charge if it has more protons than electrons. It will have negative charge if it has more electrons than protons. Q: What is the basic unit of matter? A:
OPTIONS:
- nucleus
- dark material
- neutron
- atom
output: atom

Problem: OPTIONS:
- as an equation
- as a percentage
- as a positive number
- as negative number
Q: Answer the following question given this paragraph: When energy is released in a chemical reaction or process, that energy is expressed as a negative number. Figure below shows electron affinities in kJ/mol for the main group elements. Q: How is energy expressed when it is released in a chemical reaction? A:
Answer:
as negative number
