Copper's Questions And Quality
Answers
According to Newton's Second Law of Motion, if the net force acting on the object
increases while the mass of the object remains constant, what happens to the
acceleration? - Correct Answer Acceleration increases
If the Earth were moved to half its current distance from the Sun, how would the force of
gravity by the Sun on Earth change? - Correct Answer It would become four times
stronger
What did Newton's Law of Universal Gravitation tell us about how gravity works? -
Correct Answer The force of gravity from the sun will be stronger on an object with
more mass
The Earth radius is about 6400 km. If you were in orbit in the Space Station 150 km
above the ground, the force of gravity you feel from Earth would be... - Correct Answer
Slightly weaker than when you are standing on Earth
If you were to sit on the ground, there would be a force due to gravity pulling you toward
the Earth. Which of the following is true according to Newton's 3rd law? - Correct
Answer You are pushing the Earth away from yourself with the same amount of force
What would happen to the Earth if the Sun's gravity somehow 'turned off'
instantaneously? - Correct Answer It would continue to move in a line in the same
direction it was moving when the gravity turned off
Consider a planet whose rotation axis is NOT tilted with respect to its orbital plane.
What are the seasons like on this planet? - Correct Answer There are no seasons
If the Earth rotated on its axis more slowly than it does now... - Correct Answer Its days
would be longer
If Earth had its orbit changed so that at all points along its orbit it were always the same
distance from the Sun (circular orbit), how would this affect the seasons on Earth? -
Correct Answer They would be the same as they are now
A new planet orbits its star faster than the Earth orbits the Sun and it rotates more
slowly than the Earth rotates. Which of the following is true? - Correct Answer The new
planet has a shorter year than Earth and a longer day than Earth
What time of year is it dark all day (and night) at the South pole of Earth? - Correct
Answer June
, If Earth's Moon was Full on May 1, 2007, when was it next in the First Quarter phase
after this full moon - Correct Answer May 22
How much of the total surface area of the Moon is illuminated by Sunlight during the Full
Moon phase - Correct Answer One half
At approximately what time does the third quarter Moon rise? - Correct Answer
Midnight
Approximately two weeks after a Solar Eclipse, what phase will the Moon be in? -
Correct Answer Full
A moon orbits a planet in exactly the same plane as the planet orbits its star. How often
does this planet experience a solar eclipse? - Correct Answer Once every orbit of its
moon (its month)
What is the relationship between wavelength and frequency? - Correct Answer If the
frequency increases, the wavelength decreases
Compare frequency of x-ray versus regular light - Correct Answer The X-ray has a
larger frequency than visible light
Compare the frequency and wavelength of a gamma ray with visible light - Correct
Answer Gamma ray frequency is higher and its wavelength is lower
If the frequency of radiation is twice as large then its wavelength is... - Correct Answer
half as large
Compared to blue light, red light has... - Correct Answer longer wavelength, smaller
frequency, smaller energy
Which types of radiation have the lowest energy? - Correct Answer infrared radiation
and radio
The spectrum of an oxygen lamp looks different than the spectrum of a sodium lamp
becasuse: - Correct Answer each atom has a unique set of electron orbits
Dark lines in an absorption spectra represent: - Correct Answer particular energies of
light coming from a distant object that are absorbed by material in between
Which of the following is false? - Correct Answer The energy of a photon increases in
proportion to the wavelength of the radiation
Which of the following is true? - Correct Answer An absorption spectrum appears as a
continuous spectrum interrupted by a series of dark lines
