Observing sunspots, and checking sunlight for the Doppler effect. There are probably a few others, too.

How fast earth rotates on its axis in one second?
The Earth rotates at a rate of slightly over 15 arc-seconds per second.The actual speed of rotation depends on latitude. It's greatest at the equator. At the equator, the Earth's rotation speed is about 465 meters per second.
Is this true or false the length of a planet's year is determined by how fast it spins?
False, the speed it spins on it's axis determinds the length of day. The speed it rotates the sun determinds the length of it's year.
HOW FAST DOES Neptune ROATATE?
Neptune rotates on its axis at a speed of about 16 hours and 6 minutes, resulting in a relatively slow rotation compared to Earth's 24-hour day. This means that Neptune has a longer day than Earth.
Does jupiter has a longer day than earth?
No. Jupiter rotates very fast, and a "day" on Jupiter is a little under 10 hours long.
How fast does Mercury rotate and revolve?
Rotation speeds are given in terms of angular units per time, not in terms of distance per unit time (eg km/h) which do not make sense unless a radius is given - the larger the radius, the more distance is covered by the same angle. Uranus rotates once every 17 hours, 14 minutes, 24 seconds giving it an angular velocity of about 20.88 degrees/hour. With an equatorial radius of about 25,559 km, the equator travels at about 9,320 km/h around the axis of spin. The pole with a radius of 0 km travels at 0 km/h around its axis - it just rotates on the spot!
Which planets rotates fast?
Jupiter rotates fastest at 9.9 hours and is closely followed by Saturn which rotates on its axis in 10 hours.
How fast is the earth spinning on it's axis?
The Earth rotates once per day.
How slow or fast does earth rotate?
The planet Earth rotates on its axis exactly once per day.
How does Saturn spins?
It spins around a fixed axis once every 10 hrs 14 min, which is fast enough to make the equatorial diameter 9.8% large than the polar diameter.
What are methods for determining field permeability?
Permeability is a measure of how fast water will flow through connected openings in soil or rock
What shape can a star be?
Usually it should be spherical. However, if it rotates very fast, it will be an elipsoid.Usually it should be spherical.

Does neptune have any special featurs?
Yes. It rotates about its axis once in every 16 Earth hours. That is immensely fast for a giant planet. (Contrast this with Earth's 24-hour period of rotation).

What planet rotates as fast as earth?
Mars
Is this true or false the length of a planet's year is determined by how fast it spins?
False, the speed it spins on it's axis determinds the length of day. The speed it rotates the sun determinds the length of it's year.
Why is a winter day colder than a summer day even though we are closer to the sun in the winter?
Because the earth's axis is tilted. From September to March, the Northern hemisphere is tilted away from the sun. This means that the sun is at a lower angle and doesn't heat the atmosphere as well as it does in summer -- so it's colder.
Which planet rotates more slowly than any other?
Venus (about once a year). Not Mars, it rotates almost as fast as Earth.
