What is the mechanical advantage of a lever?
A lever can use a small force over a small distance to produce a large force over a large distance at the opposite end of the lever.

Earth Science
Advancement in fossil dating methods have provided important evidence for physicists studying the big bang theory.
Statement that illustrates the impact of a natural science discovery in another discipline.
A better understanding of the physical properties of sound has allowed for developments in liquid crystal displays.
Statement that illustrates the impact of a natural science discovery in another discipline.
Why must an Earth scientist understand chemistry?
Because chemical processes occur during the formation of sedimentary rocks and the processes in the core reflect processes occurring in the ocean.
Hypothesis must be falsifiable, and results must be repeated.
This statement is a requirement of Scientific Inquiry.
What makes a systems approach valid for scientific study?
Enables scientists to take into account the various parts of a system when making predictions about system behavior
What is the difference between a law and a theory?
Law explains why something should happen, Theory explains how something will happen.
Aristotle believed that heavier objects fall faster than lighter ones based on his observation. How did new modes of thinking change his hypothesis?
Galileo experimented with different sized objects of the same material, nothing that they all fell at the same rate.
How does the big bang theory serve as a unifying theme in cosmology?
It explains a wide variety of physical processes including thermonuclear fusion and gravitational contraction of stars.
Name 2 actions that produce a decrease in both the electrical force and the gravitational force between two charged objects.
Decreasing the electrical charge and the mass of both objects. Increasing the distance between the objects.
A certain mass of hydrogen atoms is fused together within the Sun every second to become a lesser mass of helium atoms, and the missing mass is released as a radiant energy.
This describes the primary thermonuclear reaction that occurs within the sun.
2 phenomena that are the result of gravity between the moon and the earth.
Earth pulling the moon toward it. Phases of the moon.
Reason as to why did the discovery of cosmic background radiation wavelength of 7.35cm help to support the big bang theory of the universe.
Wavelength matches the predicted value for the current temperature of the universe. Radiation is coming from the center of the universe and expanding outward.
