Question 1 - 10
• How many significant figures are in the
number 109.084
• 6
Question 1 - 20
• Convert the following number into scientific
notation 8,094
• 8.094 x 10^3
Question 1 - 30
• Convert 456 hectometers into meters
• 4.56 meters
Question 1 - 40
• Convert 97 centimeters into inches (1
inch=2.54 centimeters)
• 38 inches
Question 1 - 50
• Give 3 examples of base units
• Meter, liter, second, gram, Kelvin
Question 2 - 10
• If you have two objects and they increase in
size, is the force of going to increase or
decrease?
• increase
Question 2 - 20
• What is the formula used to calculate
velocity?
• Velocity= distance/time and include the
direction
Question 2 - 30
• What is Newton’s 3rd law of motion
• For every action there is an equal and
opposite reaction
Question 2 - 40
• What is true of the acceleration of ALL objects
near earth’s surface?
• ALL objects accelerate at the same speed
regardless of their size or weight (they all
accelerate at 9.8 m/s^2)
Question 2 - 50
• Describe how mass is related to inertia
• Objects with a larger mass have greater inertia
(are harder to stop and start) objects with a
smaller mass have less inertia(are easier to
stop and start)
Question 3 - 10
• The highest part of a wave is called the
_____________.
• crest
Question 3 - 20
• Half of the distance from crest to trough is
called ________________.
• amplitude
Question 3 - 30
• What type of wave requires a medium?
• Mechanical wave
Question 3 - 40
• What type of wave moves perpendicular to
the movement of the medium
• Transverse wave
Question 3 - 50
• What is the difference between constructive
and destructive interference
• Constructive-two waves that combine to form
a wave that is bigger than either original
• Destructive-two waves that combine to form a
wave that is smaller than either original
Question 4 - 10
• What is a positive and a negative of
nonrenewable resources?
• Positive: they are cheap and
abundant(common)
• Negative: they are bad for the environment
and we will run out of them eventually
Question 4 - 20
• What type of plate boundary has plates
coming together AND one plate moves
underneath the other?
• Subduction ( a type of convergent boundary)
Question 4 - 30
• Describe what conduction is
• Energy transfer through object that are in
contact
Question 4 - 40
• How does convection impact the formation of
the Earth?
• Convection currents in the mantle cause
hotter particles to rise pushing tectonic plates
around the surface of earth
Question 4 - 50
• Describe three ways that water can be
polluted. Your examples should each be in a
different part of the water cycle.
• Car/factor emissions-in the air during
evaportation
• Pesticides-in groundwater
• Oil spill-in surface waters
• Acid rain-during precipitation
Question 5 - 10
• how do all stars begin their lives
• As a nebula (cloud of dust)
Question 5 - 20
• How do small and medium mass stars end
their lives?
• As black dwarfs
Question 5 - 30
• Describe what the big bang theory is
• The theory that the universe began as a tiny,
compact ball and expanded outward to create
the universe that is exists and is continuing to
expand outward today
Question 5 - 40
• Describe how stars create energy/light
• Nuclear fusion caused by the combination of
hydrogen into helium and the extra energy
being emitted as light
Question 5 - 50
• After nuclear fusion occurs in the core what
two zones does the light energy transfer
through, AND describe how the energy is
transferred in each zone
