Astro 7N Unit 1 Quiz with Verified Answers Rated A
according to newton's second law of motion, if the net sun and it rotates more slowly than the earth rotate. which
force acting on the object increases while the mass of the of the following is true? - ANSWER -the new planet
object remains constant, what happens to the has a shorter year than earth and a longer day than earth
acceleration? - ANSWER -acceleration increases
what time of year is it dark all day (and night) at the south
if the earth were moved to half its current distance from pole of earth? - ANSWER -june
the sun, how would the force of gravity by the sun on the
earth change? - ANSWER -it would be four times
stronger why isn't there an eclipse every month on earth -
ANSWER -the moon's orbit around earth is actually
tipped about 5 degrees to earth's orbit around the sun so
what did newton's law of universal gravitation tell us about the moon isn't always in the right plane for an eclipse to
how gravity works? - ANSWER -the force of gravity occur
from the sun will be stronger on an object with more mass
what is the inclination of mars? - ANSWER -about 1
the earth radius is about 6400 km. if you were in orbit in degree
the space station 150 km above the ground, the force of
gravity you feel from earth would be - ANSWER -
slightly weaker than when you are standing on earth how often does mar's moon, phobos, eclipse? -
ANSWER -every orbit
if you were to sit on the ground, there would be a force
due to gravity pulling you toward the earth. which of the how long is phobos orbit around mars? - ANSWER -
following is true according to newton's 3rd law? - about 8 hours
ANSWER -you are pushing the earth away from
yourself with the same force
do you see which way the stars are moving as the movie
plays? - ANSWER -east to west
what would happen to the earth if the sun's gravity
somehow turned off instantaneously? - ANSWER -it
would continue to move in a line in the same direction it do you see which way the north celestial pole (the point at
was moving when the gravity turned off the tip of the arrow just above n) is moving as the movie
plays? - ANSWER -it remains in place
consider a planet whose rotation axis is not tilted with
respect to its orbital plan. what are the seasons like on summer solstice: the ____ right? - ANSWER -june
this planet? - ANSWER -there are no seasons 21
if the earth rotated on its axis more slowly than it does autumnal equinox -- that's on or about ____ right? -
now - ANSWER -the days would be longer ANSWER -september 22
if earth had its orbit changed so that at all points along its so at the winter solstice, at noon, the sun is in (that is,
orbit it were always the same distance from the sun appears in front of) which zodiac constellation? -
(circular orbit), how would this affect the seasons on ANSWER -Sagittarius
earth? - ANSWER -they would be the same as they
are now
at midnight on march 21, we would be looking at ____
assuming the sky is clear! - ANSWER -virgo
a new planet orbits its star faster than the earth orbits the
