Which of these is true about scientific theories and scientific laws?
A law describes something specific that always happens, while a theory explains why or how a range of
phenomena happen.
A theory is about something very specific, while a law covers a broad range of phenomena.
Laws are those theories that scientists have agreed at research conferences to accept.
Laws are theories that have been thoroughly tested and proved true. - ✔✔A law describes
something specific that always happens, while a theory explains why or how a range of phenomena
happen.
Laws are very specific statements, while theories are explanations of how or why a broad group of
phenomena happen.
If new data were found to disagree with a long-standing theory, which of the following could
happen? The theory would continue to be accepted.
A vote would be taken by scientists on whether to accept the new data.
The new data would be considered wrong.
The theory could be modified or discarded. - ✔✔The theory could be modified or discarded.
In light of new data, the theory could be modified or discarded.
Which of these BEST describes how atomic theory developed?
John Dalton deduced that matter consisted of atoms made from electrons and nuclei.
Ancient scholars in Greece postulated that matter is made of atoms that consist of electrons
circling nuclei.
J.J. Thomson discovered that matter consists of atomic nuclei and electrons.
,Many people at different times contributed to the discovery of the atomic nature of matter and
subatomic particles. - ✔✔Many people at different times contributed to the discovery of the
atomic nature of matter and subatomic particles.
Why is it useful for there to be an official size for each unit?
to allow people in different locations to compare measured values
to encourage people to include units in their calculated answers
to encourage use of metric units
to keep units from getting too large or too small - ✔✔to allow people in different locations
to compare measured values
People in diverse locations can communicate about the lengths of time intervals, the sizes and masses
of objects, and relay other measurements, and all agree on what the numbers mean because the units
used have precise official values.
Which of the following is the closest to your height?
2m
2 mm
2 cm
2 km - ✔✔2m
Which of these has values that are expressed in terms of derived SI units?
mass
length
time
speed - ✔✔speed
What is the SI base unit for mass?
gram
pound
kilogram
, ounce - ✔✔kilogram
Which pair of variables are inversely related to each other?
the speed of a river and volume of water that flows each minute
the length of a side of a square and the area of the square
the speed traveled and the time needed to travel a specific distance
the volume of a liquid and the mass of the liquid - ✔✔the speed traveled and the time needed
to travel a specific distance
As your speed increase, your time of travel decreases.
The sun produces its energy by nuclear fusion reactions, in which smaller nuclei are combined to
produce larger nuclei. Forces responsible for the nuclear fusion are called nuclear forces. The physical
science that studies nuclear forces is: - ✔✔Physics.
The physical science that is BEST for finding the best locations to drill for the petroleum used to make
the candles is - ✔✔Earth science is best suited to study Earth's structure, including the
mechanisms and likely locations for petroleum reservoirs to collect.
Acidic soil water reacts with common rock-forming minerals to release ions and form new minerals.
Which physical science is BEST for studying these processes?
physics
chemistry
Earth science - ✔✔Chemistry is needed to study interactions of substances that create new
substances. Chemistry focuses on the study of atoms and molecules, their structures, and their
interactions to form various substances.
The science BEST for studying photosynthetic bacteria is - ✔✔Life Science
Which of these terms BEST describes a research project in which a big telescope is placed on a
high mountain in Arizona to study the brightness stability of the sun?
a laboratory experiment
a controlled experiment
