ASTRO 7N exam
what two properties effect the gravity we feel on its surface? - correct answer-mass and
radius
if the frequency of radiation is twice as large then its wavelength us - correct answer-half as
large
ay there were a planet X in our Solar Syatem with a mass 1/4 the mass of earth and a radius
1/2 the radius of earth how with the gravity on its surface compare - correct answer-surface
gravity on planet X is the same as on earth
comapred to blue light red light has,, - correct answer-longer wavelength, small frequency
and less energy
which would have the longest day and the longest year - correct answer-a planet that rotated
slowly on its axis and orbited the sun slowly
stars that are in the same constellation - correct answer-are likely to be at very different
distances from us
two week after the third quarter moon it is the - correct answer-first quarter moon
if a telecope 1/4 the diameter of a telescope on earth which of the following is true - correct
answer-the larger telescope can observe object fainter then the space telescope
Consider a planet whose rotation axis is NOT tilted with respect to its orbital plane. What are
the seasons - correct answer-there are no seasons
compared to a cool statr a hotter star emits - correct answer-shorter wavelength, higher
frequenct, and bluer color
the surface gravity on Mars is 40 percent of the surface gravity on earth this means - correct
answer-you can jump higher on mars than on earth
when is the wanning gibbous moon highest in the sky - correct answer-about 3:00 am
how much of the total surface ares of the moon is illuminated by sunlight during the full moon
phase - correct answer-one half
A _____ telescope uses ____ to focus light - correct answer-reflecting and mirror
which type of raqdiaqtion have the lowest energy - correct answer-infrared and radio
how often is the sun in front of a zodiac constellation - correct answer-always
