Calculate the rate of movement for the moon in degrees of azimuth per hour?

The idea is to divide the number of degrees in a complete circle (360 degrees) by the number of hours the Moon takes for those 360 degrees, i.e., one complete revolution. One revolution by the Moon takes about 27 1/2 days; convert that into hours and do the division.

The rate of movement for the moon in degrees of azimuth per hour varies depending on its position in the sky and the time of year. On average, the moon moves about 15 degrees per hour in its orbit around the Earth. However, this rate can change as the moon's orbit is not a perfect circle.

What is the Azimuth and the altitude if the latitude is 20 degree north the right ascension is 11 hour and the declination is -10 degree?
The azimuth is the compass direction, measured clockwise from true north, and the altitude is the angle above the horizon. Given the latitude of 20 degrees north, right ascension of 11 hours, and declination of -10 degrees, you would need to calculate these values using spherical trigonometry or an astronomical calculator to determine the exact azimuth and altitude.
In the horizon coordinate system altitude-azimuth how many degrees does a star at the celestial equator move in 1 hour and how many arcseconds does the star move in 1 second of time?
A star at the celestial equator will move 15 degrees in altitude per hour, and 15 arcseconds in 1 second of time. This is because the celestial equator intersects the celestial sphere at 90 degrees from the north and south celestial poles, so the stars appear to move in circles around the celestial poles.
How fast does the sun move over the surface of the earth as perceived from earth and how does one calculate that speed at various latitudes?
One day is 24 hours, so the apparent movement of the Sun is one full circle - or 360 degrees - every 24 hours. That is equivalent to 15 degrees per hour. That's the speed of the Sun as perceived from Earth - and such an apparent movement of an object in thesky has to be expressed in angular measurement (such as degrees or radians), not in meters/second, kilometers/hour, etc. Also, this apparent speed is the same at different latitudes. Actually, it can be slightly less when the Sun is not at the equinox, since then, the Sun doesn't describe a major circle from our point of view. But the difference is not great.
For every 15 degrees of longitude there is difference of how much time?
For every 15 degrees of longitude traveled eastwards, there is typically a time difference of one hour ahead. This is due to the Earth's rotation at 15 degrees per hour.
How many dagrees is the earths rotation every hour?
1 day = 1 360 degree rotation and that is also 24 hours, so the shift per hour is 360/24 = 15 degrees /hour
What is the Azimuth and the altitude if the latitude is 20 degree north the right ascension is 11 hour and the declination is -10 degree?
The azimuth is the compass direction, measured clockwise from true north, and the altitude is the angle above the horizon.

How many degrees does the hour hand move in an hour?
360 degrees
How many degrees does the hour hand move in one half of an hour?
It takes twelve hours for the hour hand to move 360 degrees In half an hour the hour hand moves 15 degrees
How many degrees of longitude there are per hour?
15 Degrees per hour
Looking at a standard wall clock at the time 6 30 what is the angle in nearest degrees created by the minute hand and the hour hand?
The angle between the hour hand and the minute hand on a standard clock at 6:30 is 15 degrees. Let's review the movement of the hands of the clock specific to this problem. The hour hand moves through the 12 hours of half a day in 12 hours (naturally), and that translates into the hour hand moving 360 degrees in 12 hours. That means the hour hand moves 360/12, or 30 degrees per hour. That translates into 15 degrees in half an hour. If the hour hand is pointing straight down at 6:00 (which it is), it will move 15 degrees from where it was in half and hour. And the time will be 6:30 with the minute hand pointing straight down. The minute hand will be pointing to where the hour hand was half an hour ago. And, as stated, the hour hand will have moved from dead on the six and gone 15 degrees further around.
What is the relationship between a degrees in rotation and an hour on the clock?
The hour hand on a standard 12 hour clock rotates one twelth of 360 degrees in one hour. That is 30 degrees.
In the horizon coordinate system altitude-azimuth how many degrees does a star at the celestial equator move in 1 hour and how many arcseconds does the star move in 1 second of time?
A star at the celestial equator will move 15 degrees in altitude per hour, and 15 arcseconds in 1 second of time. This is because the celestial equator intersects the celestial sphere at 90 degrees from the north and south celestial poles, so the stars appear to move in circles around the celestial poles.
How many degrees does the hour hand move in 23 hour?
23/24 of 720 degrees = 690 degrees
How do you calculate Greenwich hour angle?
The calculation is an hour for every 15 degrees you are away from the Greenwich meridian . You need to know your longitude , then do the calculation . Remember to do plus or minus depending if you are East or West....... eg. if you are in mid Atlantic somewhere , say 45 degrees West .....its minus three hours..

What is the angular speed of hour hand?
The angular speed of the hour hand is 30 degrees per hour because the hour hand completes a full rotation of 360 degrees in 12 hours. Therefore, 360 degrees divided by 12 hours is equal to 30 degrees per hour.
What is one hour of time equal to longitude degrees?
One hour equals 15 degrees.
