What is the angular separation between Polaris and Arcturus?
DamianDamiangp6752
The declination of the star Arcturus is 19 degrees, 11 minutes, while Polaris has a declination of 89 degrees 15 minutes. Their angular separation is the distance between them, approximately 71 degrees.

What time does the star Arcturus rise on February 10?
The answer depends on where you are. Arcturus has a declination of 19¼ degrees north, which means it passes overhead at all places with a latitude of 19¼ degrees north. For a places further north than 70¾º north Arcturus never sets at all. Alternatively for places south of 70¾º south it never rises. In between, it depends on the latitude.
How is polaris used by navigators in the northern hemisphere?
Most of the time, Polaris is used by navigators to determine the true heading of the craft (either an airplane or a ship). Polaris is called the "North Star" or "Pole Star" because the earth's axis, South Pole to North Pole, points toward it. So, it seems like it is directly above the North Pole, but is about 3/4 of a degree off. Using celestial data tables, Navigators determine what the angular difference is between true north and Polaris. Using a sextant mounted in a flat circular ring fixed on the centerline of the craft, they measure the angle from the center-line of the craft to Polaris (adjusted for the angular difference between true north and Polaris), and so can determine the direction the craft is heading. Polaris is not a very bright star, but is can be used as a navigational star. High cirrus clouds or even the light from the moon can make seeing Polaris difficult. So, generally it is not used because of the availability of brighter navigational stars. In relatively calm seas and air, celestial navigation can be accurate within a few miles and was critical to accurate navigation of craft across the oceans until the late 20th Century when global positioning satellite systems and onboard computer sytems became widely available. Now, these computer systems (when operating) are accurate within a few feet. But, when those systems go down, that old sextant will still work.

If the angle between Polaris and the horizon is 40 degress what is your approximate latitude?
The latitude would also be approximately 40 degrees in this case.
What is the angular separation from the pointer star to Arcturus?
I do not know which star is the one you refer to as "Pointer Star" but Arcturus has a declination (angle above the celestial equator) of +19° 10′ 56″. If yout "Pointer Star is "Polaris" then the angular distance between these stars is (90° - 19° 10′ 56″) or 70° 49' 04"
How would the angular separation of interferences fringes in young's double slit experiment change when the distance of separation between the slits and the screen is doubled?
Note that bandwidth = lamda D / d and bandwidth = D @ Here @ is the angular separation. So @ = lamda D / D d = lambda / d So as D is not there in the expression the angular separation remains the same though the distance between slits and the screen is doubled.
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.
What is the Relation between angular velocity and frequency?
If there is a rotation, "angular velocity" and "angular frequency" is the same thing. However, "angular frequency" can also refer to situations where there is no rotation.
What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum.
What is relation between linear velocity and angular velocity?

What is the difference between angular distance and angular displacement?
Here's the easiest answer: They have different names.....
Relation between linear velocity and angular velocity?
linear velocity= radius* angular velocity

Why Vega brighter than Arcturus?
The apparent brightness of stars depends on:* The distance * The actual brightness * In some cases, the brightness may be dimmed by clouds of dust and gas, between us and the distant star. In the case of Vega and Arcturus, Vega is NOT brighter than Arcturus. Their apparent magnitude (brightness) is about the same, with Arcturus perhaps being slightly brighter, depending on the source consulted. In terms of real brightness ("absolute magnitude"), Arcturus is actually brighter. When consulting numbers, please remember that smaller numbers refer to brighter objects.
What is the difference between linear momentum and angular momentum?
angular mmtm is a cross product unlike linear momentum
