d. spiral
Scintillation counters are widely used in medical imaging used to measure radioactive contamination, radiation measurement gauges, radiation measurement testing, nuclear power plant safety, and radiation.
Scintillation is the process by which the energy of a specific radiation interacting with a certain amount of sensitive material (called a scintillator) is converted into electromagnetic waves. The frequencies of the electromagnetic waves emitted are in or near the visible spectrum.
A scintillator is a substance that exhibits scintillation, the property of luminescence, when excited by ionizing radiation. When a luminescent material collides with an approaching particle, it absorbs the energy and glows (that is, it re-emits the absorbed energy in the form of light).

Answer:
Federal government spending went up to very high levels during World War II. After plummeting immediately after the war, it went back up (although not to World War II-levels).
Explanation:
Besides funding gigantic military-industrial operations, the government also funded for military purposes a huge part of the most advanced scientific and technological research and development in the postwar United States, which led Eisenhower to warn also against the "danger that public policy could itself become the captive of a scientific technological elite" (Eisenhower 1961, 654).
From 1950 to the late 1960s, the dominant Cold War ideology and a bipartisan consensus on defense and foreign policy, focused on global containment of communism and deterrence of a Soviet attack on the United States or its allies, gave nearly unchallenged support to the unprecedented allocation of resources to the "peacetime" military establishment.
Answer: Internalization
Explanation: Internalization simply refers to the integration of other people view or beliefs into one's own beliefs. It's involves adopting the values into one's own identity. Internalization goes through processes which includes; first receiving the information, viewing it through the perspectives of the communicator, believing his views and finally adopting it as you own way of life or ideology.
Kinetic energy is the energy the body possesses due to its motion. Kinetic energy is a kind of mechanical energy, as well as potential energy. All bodies that move linearly or rotate possess a certain kinetic energy.
Potential energy is the energy that an object has due to its position relative to another object. When we stand on the top of the building, we have more potential energy than when we are at the bottom, because the earth is attracted by the force of gravity.
When the body falls, it at the beginning of the fall has potential energy due to the force of gravity, and therefore falls, and then the potential energy turns into a kinetic, because the body moves in the fall.
When we kick the ball upwards, it moves upward, because it has kinetic energy, until it stops at one point, since there is no kinetic energy of motion, and only at that moment the kinetic energy turns into a potential, at that moment the ball is stopped, until it starts to fall again.
Correct answers are II. and III.
The late 1800’s-early 1900’s were a trying time for the nation of Russia due to many events. These harsh times began in the 1890’s with the bad living and working conditions in the country that led to many strikes and revolts. A major revolt occurred in 1905 after the creation of radical factions/political parties. The Tsar (ruler) was not able to keep control or repair the sluggish economy. In both, 1905 and 1914 Russia found itself at war, which both led to embarrassing defeats, revolution, and the overthrow of the Tsar.
