What is the moons two motions?
Rotation and Revolution.
Why the moons appear at night?
Due to Earth's rotation.
What is the length of Saturn's rotation on its axis?
The length of Saturn's rotation on its axis is about ten and a half hours.
What is the length of rotation of the earth's moon?
the length of the moon's rotation is 27.3 days (about 1 month)
Why do some planet have shorter days then earth?
The length of a planet's day is determined by the speed of it's rotation on it's axis. The faster the rotation, the shorter the day. The slower the rotation, the longer the day. This is affected by many factors such as any moons the planet may have (orbital speed, rotation speed or tide lock, distance and direction of travel of the moons all should be considered), past collisions with other large bodies (planetoids and other planets and their moons), and how the stellar dust and debris were moving and colliding when the planet was formed. Some planets are tide locked to their star and have no rotation and therefore no relative "day". One side faces forever toward the blazing heat of it's star, while the other side faces an eternal frozen night.
What is Europa's length of day?
Europa, one of Jupiter's moons, has a synchronous rotation period that matches its orbital period around Jupiter, resulting in a length of day of approximately 3.5 Earth days. This means that it takes about 85.2 hours for Europa to complete one full rotation on its axis. Thus, one day on Europa is significantly longer than an Earth day.
Calculate specific rotation?
by this law specific rotation =degree of rotation /concentration of a substance *length of sample tube
What is the period of rotation and the number of moons on the chart on page 63 in astronomy?
9326
What causes the apparent repeated changes of the moons shape?
The Earth's and Moon's rotation.
Explain the Moons period of rotation versus period of revolution.?
They are precisely equal.
What is the result of the moons period of rotation?
how is the crater density used in the relative dating
How do you use the moons movement and phases to tell time?
you use the moons movement and phases to tell time because of the seasons, rotation, and revolution
