Answer the following question given this paragraph: Solid-state radiation detectors convert ionization produced in a semiconductor (like those found in computer chips) directly into an electrical signal. Semiconductors can be constructed that do not conduct current in one particular direction. When a voltage is applied in that direction, current flows only when ionization is produced by radiation, similar to what happens in a Geiger tube. Further, the amount of current in a solid-state detector is closely related to the energy deposited and, since the detector is solid, it can have a high efficiency (since ionizing radiation is stopped in a shorter distance in solids fewer particles escape detection). As with scintillators, very sophisticated information can be obtained from solid-state detectors. PhET Explorations: Radioactive Dating Game Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. Q: Solid-state radiation detectors convert ionization produced in a semiconductor (like those found in computer chips) directly into what? Choices: - thermal energy - microwaves - isotopes - electrical signal A:
(A).
electrical signal
Ques:Answer the following question given this paragraph: As you would expect, where plates collide there are lots of intense earthquakes and volcanic eruptions. The subducting oceanic plate melts as it reenters the mantle. The magma rises and erupts. This creates a volcanic mountain range near the coast of the continent. This range is called a volcanic arc . The Andes Mountains, along the western edge of South America, are a volcanic arc ( Figure below ). Q: What is formed when a subducting plate flows under another tectonic plate? Choices: - magma - boundary plate - fault line - volcanic arc A:

Ans:volcanic arc
Answer the following question given this paragraph: Energy is conserved in a closed system. That is, if you add up all the energy of an object(s) at one time it will equal all the energy of said object(s) at a later time. A closed system is a system where no energy is transferred in or out. The total energy of the universe is a constant (i. e. it does not change). The problems below do not consider the situation of energy transfer (called work). So friction and other sources where energy leaves the system are not present. Thus, one simply adds up all the potential energy and kinetic energy before and sets it equal to the addition of the total potential energy and kinetic energy after . Q: What happens to energy in a closed system? Choices: - is replicated - is destroyed - is wasted - is conserved A:
is conserved
