Why should the graduated cylinder be cleaned and rinsed after measuring out each solution?
If you are going to measure out a different solution, you must rinse and drain well to avoid contaminating one substance with another. If you are using the same solution, there is no need to rinse, and in fact it is better not to do so, because the rinsings will dilute the next batch.
How can you avoid constant error?
By regular practice
What is the opposite Glance?
Avoid eye contact.
Where should you position your eye in order to avoid parallax error?
It should be in the same horizontal line as the meniscus of the liquid
How do you read a tuberculin syringe?
To read a tuberculin syringe you simply have to look at the calibrations on the syringe. Make sure that your eye is level to avoid taking a wrong reading as a result of parallax.
Why should you avoid parallax?
There is no such way to avoid parallax error, you just have to be careful.. :)

Write the precautions to be taken while using meter scale?
Following are some precautions to be taken while measuring length with the help of a metre scale: Scale must be placed in contact with the object along its length. Eyes must be exactly perpendicular to the point where the measurement is to be taken, to avoid parallax error. If the ends of a scale are broken/damaged we should avoid taking measurements from the end. Instead, we should place the object on any other fully visible mark on the scale (say, on 2 cm instead of 0). Then you must subtract the reading on this mark from the reading at the other end.
When land surveying how is parallax corrected?
Parallax in land surveying is corrected by ensuring that the line of sight through the telescope is parallel to the horizontal cross-hairs or line of collimation. This can be done by adjusting the focusing knob until the image is sharp, and by maintaining a consistent viewing position. By minimizing parallax error, surveyors can obtain accurate measurements and avoid distortions in their readings.
Why 4 and 6 markings absent in Williams probe?
1. to avoid parallax error 2. to easily distinguish between shallow and deep pockets
How parallax can be avoided?
To help the user avoid this problem, the scale is sometimes printed above a narrow strip of mirror, and the user positions his eye so that the pointer obscures its own reflection. This guarantees that the user's line of sight is perpendicular to the mirror and therefore to the scale. Parallax is thus avoided.
How does the parallax error affect your measurements?
Parallax error is the most common source of both systematic and instantaneous anomaly in experiments involving analogue measurement and great care should be taken to avoid it when recording data, supported also by repetition of each independent variable data collection stage.

What to avoid when taking fosamax?
Avoid taking other medications including vitamins, calcium, or antacids for at least 30 minutes after taking Fosamax. Consult a physician before taking any medication that is an anti-steroidal anti inflammatory to avoid any drug interactions.
What is parallax and why should you avoid it?
parallax is an error. like when you look at a point on ruler from different angles, you see different values to get a specific and correct value you have to avoid this. avoid this by looking at the ruler from a 90o angle (straight) from the point. In video game design of the 1980s this visual distortion was used to provide a psuedo 3D effect known as parallax scrolling. The display background was segemented into three or more bands, the closest scrolled the fastest and the rear band the slowest. The other bands scrolled at an intermediate speed. This gave the impression that the screen was moving with depth. This technique has been replaced with mathematical based 3D systems like vector coordinates and Euclidean math.
