takes the same time to rotate on its axis
similar atmosphere
same gravity on the surface

We believe the maria on the Earth's Moon are
Group of answer choices
ancient impact craters in which lava beds welled up from inside
the Moon
giant volcanoes produced when the Moon tried to get plate
tectonics going
large rifts filled with colder material made when the Moon's...
What is the round-trip travel time of light from Earth to
Neptune (at a distance of 30 AU)? How far would a spacecraft
orbiting the planet at a speed of 0.5 km/s travel during that
time?
How far would a spacecraft orbiting the planet at a speed of 0.5
km/skm/s travel during that time?
a) What is the angular momentum of the Moon around the Earth?
The Moon mass is 7.40e22 kg and it orbits 3.80e8 meters from the
Earth.
b) And what is the angular momentum of the Earth around the Sun?
Mass of the Earth is 5.98e24 kg and it orbits 1.50el 1 m from the
Sun.
What would the electric force of the Moon on the Earth
be if the Moon had 10^52 electrons attracting an equal number of
protons in the Earth? The Earth-Moon distance is 400,000km. Given
the value you got (compare to gravity between the Earth &
Moon), why do we ignore electrical forces at astronomical
distances?

A galaxy is receding from Earth at 15,000 km/s. If one of the
characteristic wavelengths of light emitted by the galaxy is 550
nm, what corresponding wavelength will be measured by observers on
Earth?

Moon effect. Some people believe that the Moon controls their
activities. If the Moon moves from being directly on the opposite
side of Earth from you to being directly overhead, by what
percentage does (a) the Moon's gravitational pull on you increase
and (b) your weight (as measured on a scale) decrease? Assume that
the Earth–Moon (center-to-center) distance is 3.82 × 108 m, Earth's
radius is 6.37 × 106 m, Moon's mass is 7.36 × 1022 kg, and Earth's
mass...

Estimate the initial rotation period of the Earth if the Moon
had been torn from it, as suggested by the fission theory. Compare
your answer to the estimated rate of spin of the early Earth (5
hours or so). Is the fission theory a viable theory?
