KAPLAN SC200 UNIT 4 QUIZ (LATEST 2015)

Question 1. Question :
What kind of energy does a person experience during skydiving?
potential gravitational energy
potential energy
chemical energy
heat energy
kinetic energy
Question 2. Question :
Which of the following is not a fossil fuel?
coal
wood
petroleum
natural gas
Question 3. Question :
The combination of two atomic nuclei is referred to as fusion, whereas the splitting of a single atomic nucleus is called
gamma decay
alpha decay
fission
beta decay
electron decay
Question 4. Question :
Einstein's equation, E = mc2 , states that mass can be converted into
motion
energy
acceleration
force
Question 5. Question :
A scientist who uses carbon-14 dating is actually measuring the
age of the Earth.
age of the igneous rocks.
time since the death of a living thing.
time that an artifact was made.
number of carbon ions in a material.
Question 6. Question :
The difference between nuclear fusion and nuclear fission is that
Energy is released from fusion, but not from fission.
Energy is released from fission, but not from fusion.
Fusion splits apart a nucleus; fission combines two nuclei into one.
Fusion combines two nuclei into one, fission splits apart a nucleus.
Only fission is involved in hydrogen bomb explosions; both fusion and fission are required for atomic bomb explosions.
Question 7. Question :
The first law of thermodynamics states that
potential energy is always greater than kinetic energy
in an isolated system, the total amount of energy is conserved
in an isolated system, the total amount of energy is constantly depleted
it is impossible to convert heat energy into kinetic energy

Question 10. Question :
Most of the energy in a nuclear power plant is generated by conversion of
mass into heat energy.
two hydrogen atoms into helium.
heat energy into mechanical energy.
magnetic fields into electricity.

was favored by most of the citizens in Nevada.
is a plan to bury nuclear wastes deep below the Earth's surface.
has been determined to be a failure.
Question 12. Question :
A form of an element having different numbers of neutrons in its nucleus is called
an isotope
