Which kind of force do you exert on an object when you pull it toward you?

The metricsystem was first put into practice in 1799, during the French Revolution, when the existing system of measures became impractical for trade and was supplanted by a decimal system based on the kilogram and the meter.

What is metric system?

During the FrenchRevolution, the existing system of measures became impractical for trade and was replaced by a decimalsystem based on the kilogram and the meter, and the metricsystem was born.

In 1793, the meter was defined as one ten-millionth of the distance from the equator to the NorthPole along a great circle, implying that the Earth's circumference is approximately 40000 km.

The meter was redefined in 1799 in terms of a prototype meter bar.

The meter was introduced as a new unit of length, defined as one ten-millionth of the shortestdistance between the NorthPole and the Equator passing through Paris, assuming an Earth flattening of 1/334.

Thus, this is the history of the metric system as it applies to the meter.

Answer and explanation;

In 1670 Gabriel Mouton, Vicar of St. Paul’s Church and an astronomer proposed the swing  length  of  a  pendulum  with  a  frequency  of  one  beat  per  second  as  the  unit  of length.

In 1791 the Commission of the French Academy of Sciences proposed the name meter to the unit of length. It would equal one tens-millionth of the distance from the North Pole to the equator along the meridian through Paris.It is realistically represented by the distance between two marks on an iron bar kept in Paris.

In 1889 the 1st General Conference on Weights and Measures define the meter as the distance between two lines on a standard bar that made of an alloy of 90%platinum with 10%iridium.

In 1960 the meter was redefined as 1650763.73 wavelengths of orange-red light, in a vacuum, produced by burning the element krypton (Kr-86).

In 1984 the Geneva Conference on Weights and Measures has  defined  the  meter  as  the  distance  light  travels,  in  a  vacuum,  in 1299792458⁄ seconds  with  time  measured  by  a  cesium-133  atomic  clock  which  emits  pulses  of radiation at very rapid, regular intervals.

Answer:

A.) gas is matter, and therefore has mass

Explanation:

The principle illustrated in this scenario is a. gas is matter, and therefore has mass.

When the air from one balloon is released, it creates a flow of gas in one direction. According to the principle of gas having mass, the released gas exerts a force on the hanger, causing it to tilt. This demonstrates that gas is matter and has mass.

It's important to note that gas does have volume, which can be measured. This is not the principle being illustrated in this scenario.

The principle of released gas having a higher temperature than inert gas is not applicable in this scenario, as no information is given about the temperatures of the gases involved.

The principle of matter may never be destroyed is a general principle in physics and does not specifically apply to this scenario.
