The correct answer is option (C) One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table. Measuring liquids by holding the flask at eye level is the greatest amount of error in the experiment.
When liquid is being measured in a flask, the liquid shows a curve downwards which is called the meniscus. For measuring the transparent liquids, the lower meniscus touching the graduation of the should be considered and for measuring the colored liquids, the upper meniscus touching the graduation of the flask should be considered. When, the measurement is done by holding the flask at eye level there is always an error as it should be kept on a flat surface and measured by eyes directly leveling with the liquid. This gives a correct measurement which was done by the other student. Thus, one student measuring the liquid by holding the flask at eye level will have a wrong measurement and the other student measuring the liquid while the flask sits on the table gives the correct measurement and the results of the experiment will vary.

The best kind of model for the scientist to use is an interactive model of the planets' orbits on a computer.
<h3>What is the law of orbits?</h3>
Kepler's first law, also known as the law of orbits, describes the shape of planetary orbits. According to this law, the planet's orbits around the Sun are elliptical, despite having very small eccentricities.
For this reason, it is necessary to know all the orbits of the planets in an interactive way, since according to Kepler's law, the orbits decrease over time.
