What is the function of a sextant?
Sextant is used to measure the angle between any two visible objects.Its primary use is to determine the angle between a celestial object and the the horizon which is also know as objects altitude.
What is the angular distance around the horizon from some reference point?
If the reference point and an object are both on the horizon then the angular distance to the object, relative to the reference point is simply the angle formed between the two rays from the observer to object and to the reference point. If either the object or reference point (or both) are not in the plane of the horizon then the appropriate rays are the projections of the rays from the observer onto the plane containing the horizon.
What do you use to measure the angle of a star?
The device that astronomers use to find the angle between the horizon and stars in the sky is called a sextant.
What type of object has an acute angle?
objects that have an acute angle are a sideways v on a keyboard, a cheerleader w/ their arms up, and a triangle
Why does the acceleration of an object rolled down an incline increase as the angle of incline increases?
The contribution of the acceleration of gravity in the direction of motion increases as the angle of the incline increases. Or in other words, as the angle between the direction of motion and the force of gravity goes to zero, the acceleration of the object goes to the gravitational acceleration. a = g cos(theta) Where theta is the angle between the direction of motion and verticle, which is in fact (theta = 90 - angle of the incline)Where a is the acceleration of the object down the incline plane and g is the acceleration due to gravity. Theta is the angle between the direction of motion of the accelerating object and the acceleration of gravity. Initially, the angle between a and g is 90 degrees (no incline) and therefore g contributes nothing to the objects acceleration. a = g cos(90) = 0 As the angle of the inclined is increased, the angle between a and g approaches zero, at which point a = g. With no other forces acting upon the object, g is its maximum acceleration.
What is the function of a sextant?
Sextant is used to measure the angle between any two visible objects.Its primary use is to determine the angle between a celestial object and the the horizon which is also know as objects altitude.
What is angle measured above the altitude?
Altitude is the angle measured above the horizon.
What does altitude mean in science?
the angle between an object in the sky and the horizon
What is the correct term Zenith is the angle between an object and the horizon?
The correct term is "zenith angle." It is the angle measured from the vertical direction (zenith) to the point directly above an observer. It is used to determine the position of an object in the sky relative to the observer's horizon.
What is an angle of separation?
"The angle of separation is the angle between lines originating from the eye of the observer toward two objects, such as a star-the Sun and the horizon." (quoted from Earth in space, a student guide and source book)
What is the angular distance around the horizon from some reference point?
If the reference point and an object are both on the horizon then the angular distance to the object, relative to the reference point is simply the angle formed between the two rays from the observer to object and to the reference point. If either the object or reference point (or both) are not in the plane of the horizon then the appropriate rays are the projections of the rays from the observer onto the plane containing the horizon.
What is 45 degrees of the sun?
A 45 degree sun angle indicates that the sun is halfway between the horizon and directly overhead (known as the zenith). Such an angle causes the length of an object's shadow to be equal to the object's height.
What is the definition of angle of impact?
The angle of impact is the angle at which an object or force strikes another object. It is measured between the direction of impact and a reference line on the struck object, such as the horizontal plane. The angle of impact can affect the resulting damage or motion of the objects involved.
Is Altitude defined as the distance in degrees of a star below the horizon?
Almost . . ."Altitude" is the apparent angle of the object above the horizon.
The angle between the suns position in the sky and the horizon is what?
The angle between the sun's position in the sky and the horizon is called the altitude of the sun. It is the measurement from the horizon to the center of the sun's disk. This angle changes throughout the day as the sun moves across the sky.
What is object has an obtuse angle?
some objects that has an obtuse angle is a pentagon, laptop and the objects that is greater than 90 degrees
What is the sun's azimuth?
Azimuth tells us the direction in which a celestial object can be seen. It is the angle (clockwise) between due north and the point on the horizon directly below the object. The azimuth of the Sun thus varies with the time of day and the time of year.
