What is the exact mass of the sun?
The Wikipedia lists the mass as (1.98855±0.00025)E30 kilograms. The plus-minus, of course, refers to the probable error in the Sun's mass, as currently known. That means this mass is currently known with a probable error of about 0.01%.It is also necessary to realize that the mass of the sun is slowly but continuously decreasing. due mostly to the conversion of mass to energy in fusion (4.29E9 kilograms/second) but also the solar wind (~1E9 kilograms/second). Admittedly this mass loss is so small compared to the probable error in the total mass that it is usually ignored, but still it makes knowledge of "exact mass of the Sun" impossible.
What is zero error of traveling microscope?
Zero error in a traveling microscope refers to the discrepancy between the actual reading of the microscope when the eyepiece is aligned with the zero mark of the scale and the expected zero reading when no object is being measured. This error can occur due to misalignment or imperfections in the instrument, leading to inaccurate measurements. It is crucial to identify and correct zero error before taking measurements to ensure precision in the results obtained with the microscope.
What does parallax error mean?
Parallax error refers to the apparent shift in the position of an object when viewed from different angles, causing a discrepancy in measurement. This error occurs when the observer's line of sight is not aligned with the measurement scale, leading to inaccurate readings. It's commonly encountered in various fields, such as photography, surveying, and instrumentation, where precision is crucial. To minimize parallax error, it's important to ensure proper alignment and viewing angles when taking measurements.
How much is a 1974 20 star note error worth?
You need to be more descriptive of what the error is. There are multiple paper money errors with some being worth no more than normal notes (minor cutting errors) to some being worth thousands of dollars (double denomination mules), without knowing what error you think you have, it is impossible to accurately value your coin.
Your starite heater has error code E01?
Error code E01 on your starite heater usually indicates a problem with the water flow or pressure. Check to see if the water flow is adequate and that there are no obstructions in the filter or pump. If the issue persists, you may need to contact a professional technician to further diagnose and repair the problem.
What is a transit bearing used for?
A transit bearing is used for 1. Obtaining the compass error 2. Can be useful during course alteration points in areas of heavy traffic density 3. Transit bearings can be used as leading lights 4. Can be to check if a vessel is dragging anchor. 5.Gives us a position line
What does the abbreviation you I C E stand for in relation to the prismatic compass?
Individual Compass Error.
What does ice stand for in relation to prismatic compass?
In relation to a prismatic compass, ICE stands for "Index Correction Error." It refers to the error caused when the index line does not align perfectly with the zero mark on the compass card, leading to inaccuracies in readings. This error needs to be accounted for when taking bearings with a prismatic compass.
What is damping error in gyro compass?
This error is present in a compass which is damped in tilt. A compass damped in tilt always settles east of the meridian and above the horizon in NH, and vice-versa. Its magnitude depends on the observer's latitude, Sin( error ) α Tan( latitude ) At equator, the error is nil. The error is eastward in all northernly latitudes, and vice-versa. For the purpose of damping error, a latitude rider / adjuster is provided with the gyro compass which shifts the lubber line equal to the amount of error in the appropriate direction.
What is deviation gyro course from magnetic course?
Deviation refers to the error in a ship's compass readings caused by magnetic fields from onboard electrical equipment and metal structures, leading to a difference between the gyro course (the heading indicated by a gyroscopic compass) and the magnetic course (the heading indicated by a magnetic compass). This deviation can cause navigational inaccuracies, making it essential for navigators to account for it when plotting courses. The difference between the gyro and magnetic courses is crucial for precise navigation, especially in areas where magnetic anomalies may exist. Regular calibration and adjustment of the compass systems can help minimize these discrepancies.
How did Christopher Columbus use the cross staff for his exploration?
Columbus did indeed use a compass on his voyages; the compass (lodestone in its earliest incarnation) is arguably the oldest known navigational instrument. The problem is that compasses point to Magnetic North, not True North. Because of this, course errors are induced, and the degree and angle of error will change as position changes
How do you get compass error?
You are over a large amount of magnetic material (Sewage pipes, a steel building, even a large wristwatch) or your compass needle is defective.
What is the Cause of gyro compass failure in higher latitude?
It is not so much of a failure but an Heading offset caused by"Speed Error"The speed error is an error generated when a vessel/aircraft in which a gyrocompass is installed transits a course other than east or west. Its value is determined depending on the ship's speed, course, and latitude. (It is not related to the kind or type of gyrocompass.)The north-seeking tendency of a gyrocompass is based on the earth's rotation. When a ship sails, the resultant motion of the ship's motion and the earth's rotation acts on the north-seeking tendency of the gyro. If the course of the ship deviates towards the north or south, the direction of the resultant motion deviates north or south and thus an error occurs because the north-seeking force of the gyro acts perpendicular to this resultant motion. That is, the speed error is the angle of the difference between this resultant motion and the east-west direction.Determining Speed Errorϕ: LatitudeK: Speed of the earth's rotation at theequator (About 900 kt)V: Vessel/Aircraft speed (kt)θ: Gyrocompass courseδ: Speed errorIn the figure above, AC = Vcos θ = Kcos ϕ • sin δSince δ is a small value,sinδ = δ (radian) = 1/57.3 δ (unit: degree)From these equations, δ = 57.3 Vcos θ/900 cos ϕIf we assume, for example, that the ship is at the equator ( ϕ = 0), the gyrocompass course is N ( θ =0), and the ship's speed is 30 kt, thenδ = 57.3 × 30/900 = 1.91 degrees = 1°54'When the value of θ is between 270° to 90°, the compass indication increases. Therefore, theship's true course is as shown below.0° − 1°54' = 358°6'As seen above, if the compass course deviates towards the north, the true course can be obtained by subtracting the speed error from the compass course, and if the course deviates towards the south, the true course is obtained by adding the speed error to the compass course.Most modern Gyros can automatically compensate for this error when interfaced to a GPS/SatNav/GLONASS (position/Speed) and w or w/o a Speed Log (speed). These values can also be entered in Manually to calculate speed error. See CMZ900 by Yokogawa and marketed by AGMarine. Just a little plug if that's alright?In the same location when we compare 2 vessels have same heading; we can come to that conclusion from formula "57.3 Vcos θ", higher speed will cause bigger speed error.
Your compass faulty not point north?
A compass almost never points straight North. Aviation maps always show the amount of error for a given area. Errors can include your area, the proximity to ferrous materials. The quality of the compass and so on.
What is a Genetic Error?
A genetic error, or mutation, is a permanent alteration in the DNA sequence that makes up a gene. These errors can occur spontaneously or be caused by external factors, and they can result in changes to the way the gene functions, leading to genetic disorders or diseases.
What are the Error occurs when no checkbox is checked in PHP?
Suppose you have checkbox in HTML from and and you are calling that checkbox by name in php , In that case in you don't check and hit submit , You will get Undefined parameter 'name_of _checkbox' As Error.
What is compass error?
Compass error refers to a magnetic compasses natural tendencies to produce erroneous readings in certain circumstances. Sometimes this may be due to environmental effects such as proximity to a strong magnetic field. Compass error is also frequently the result of shortcomings or anomalies in the way compasses work. Compass error due to environmental effects usually refers to an airplanes compass being drawn toward the magnetic fields generated by the aircrafts engines. This is called magnetic deviation. Additionally in some regions with high concentrations of iron in the soil, compasses may give all sorts of erroneous information. Magnetic compass "variation" deals with the difference between the magnetic north pole (which magnetic compasses point to) and the true north pole (the actual geographical north pole.) While this difference may seem minor, magnetic variation can mean a difference of up to 4 or 5 degrees in some places. In aviation, compasses may also give erroneous readings when turning or performing other maneuvers. This is due to the curvature of the earth combined with the fact that the compass needle wishes to point at the magnetic north pole. Since the earth is round, and the compass points to the magnetic north pole, the compass needle will in most cases be drawn to a point below the horizon from the users standpoint. This will cause the magnetic compass to precede when turning to a northern heading, and to lag when turning to a southern heading.
