A) Oscillate

B) Liquid

C) Loosely

That is, "They can oscillate about a fixed point. Particles in a liquid are still close together but are arranged loosely (not in a pattern)

Explanation:

The above speaks to the various states that matter can be in. They are Gaseous, Liquid, and Solid.

The state described above is the liquid state. Recall that all matter are made up of microscopic particles. These particles when viewed under a microscope are observed to be in a state of continuous motion.

The degree of motion and arrangement is determined by the temprature of the substance. The higher the temperature, the faster and more lose the particles become.

Water for instance would in a liquid state, have its particles oscillate freely about each other giving it the ability to take the shape of the container in which it is put. Its particles are not rigidly fixed together at this point and can slide past each other easily.

In a solid-state (that is ice) the particles become tightly packed and there is less oscillation. Whilst in a gaseous state (vapor, that is) the particles o or molecules are very far apart.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
