0.10
,What |two |things |about |Venus |couldn't |be |explained |by |a |geocentric |cosmology? |- |CORRECT |
ANSWER✔✔-That |it |has |phases |and |changes |apparent |size.
How |would |the |mass |of |a |brick |change |if |it |were |placed |on |the |Moon? |- |CORRECT |
ANSWER✔✔-Its |mass |would |be |the |same |as |it |is |here |on |Earth.
One |statement |below |is |incorrect; |which |one?
The |rotation |and |revolution |of |the |Earth |are |in |opposite |directions.
The |rotation |of |the |Earth |is |counter |clockwise |viewed |from |the |north.
|
Leap |years |are |necessary |because |the |length |of |the |year |is |not |an |exact |integral |number |of |
days.
The |seasons |are |a |result |of |the |tilt |of |the |Earth's |rotation |axis |relative |to |the |plane |of |its |orbit |
around |the |Sun. |- |CORRECT |ANSWER✔✔-The |rotation |and |revolution |of |the |Earth |are |in |
opposite |directions.
One |statement |below |is |correct; |which |one?
In |the |time |that |the |Moon |makes |one |revolution |about |the |Earth |the |Earth |moves |through |
about |1/2 |of |its |orbit |about |the |Sun.
Because |the |Moon |does |not |rotate |with |respect |to |the |distant |stars, |we |see |all |sides |of |the |
Moon |once |each |month.
, The |plane |of |the |Moon's |orbit |is |tilted |at |about |5° |to |the |ecliptic |plane
In |its |orbit |about |the |Earth |the |Moon |has |to |travel |a |smaller |distance |to |come |back |to |the |
same |phase |than |to |make |one |full |turn |with |respect |to |the |distant |stars. |- |CORRECT |
ANSWER✔✔-The |plane |of |the |Moon's |orbit |is |tilted |at |about |5° |to |the |ecliptic |plane
The |main |reason |for |seasonal |effects |at |mid-latitudes |on |the |Earth |is: |- |CORRECT |
ANSWER✔✔-the |tilt |of |the |spin |axis |of |Earth |to |its |orbital
plane, |resulting |in |a |change |in |the |angle |of
incidence |of |solar |radiation |on |the |Eirth's
surface |as |the |Earth |orbits |around |the |Sun.
At |what |part |of |its |cycle |will |the |Moon |be
seen |high |in |the |sky |at |midnight, |from |mid-latitudes? |- |CORRECT |ANSWER✔✔-Full |moon
Which |of |the |following |correctly |describes |the
rotation |of |the |Moon? |- |CORRECT |ANSWER✔✔-The |Moon |rotates |once |per |month |to |keep
one |side |always |pointing |toward |the |Earth.
The |typical |size |of |the |shadow |of |the |Moon
when |it |is |cast |upon |the |Earth |during |a |total
solar |eclipse, |from |inside |of |which |no |part |of
the |solar |disk |is |visible, |is: |- |CORRECT |ANSWER✔✔-very |small, |with |a |typical |diameter |less
than |about |270 |km.
The |Sun |and |the |Moon |appear |to |us |to
