Today, the Moon’s orbit around
Earth has a semi-major axis of a=384,400 km and an orbital period
of 27.32166 days.
a. The Moon slowly moves outward due to tidal braking of the
Earth’s rotation, and at some future date the Moon will have an
orbital period of 47 days. Compute the semi-major axis of the
Moon’s orbit at this future date (express your answer in
kilometers).
semi-major axis = 5.5*10^5 km
b. Today, the Moon has an angular diameter of...

1) The Solar and Sidereal days difer from each other by about 4 minutes. How much distance, relative to the Sun and in km, does the Earth travel during that time? (You may approximate the Earth's orbit as a perfect circle.) 2) How many degrees does the Moon move in its orbit during one Earth-day. Use the Moon's orbital period relative to distant stars, i.e. use its sidereal period. 3) a) Since the Earth makes one full revolution every 24...

A normal rock sample from the Earth's crust contains less than 1 nanogram per gram (or 1 part per billion) of Iridium, while the Iridium clay layer associated with the K-Pg impact contains about 3 parts per billion. (a) Assume the K-T impactor was a rocky...
