Johannes Kepler was a main stargazer of the Scientific Revolution known for detailing the Laws of Planetary Motion. A stargazer, obviously, is a man who contemplates the sun, stars, planets and different parts of room. Kepler was German and lived in the vicinity of 1571 and 1630. 
Despite the fact that Kepler is best known for characterizing laws in regards to planetary movement, he made a few other striking commitments to science. He was the first to discover that refraction drives vision in the eye and that utilizing two eyes empowers profundity recognition.

There is said to be a short circuit when
DaniilM [7]

A short circuit is said to have occurred when two nodes of a circuit at different voltages are abnormally connected

There is said to be a short circuit when; <u>One part of a parallel circuit has a very low resistance and almost all the current will flow through this part and very little current will flow through the other part</u>

<u />

The correct option is option B.

Reason:

A circuit has to be closed or the the current path has to be closed for

current to flow. A short circuit occurs when current in a circuit flows

through an abnormal path, such as a bridge in a connection to a load that

creates a parallel path for current flow.

Almost all the current flows through the parallel path due to the low

resistance in the connection (almost zero) and the proximity to the power

source, thereby preventing current from reaching its intended destination

Therefore, the correct option is option B.;

Which law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant
Brrunno [24]

<u>Gay Lussac’s law</u> state that the pressure and absolute temperature of a fixed quantity of a gas are directly proportional under constant volume conditions.  

<h2>Further Explanation </h2><h3>Gay-Lussac’s law  </h3>
  • It states that at constant volume, the pressure of an ideal gas I directly proportional to its absolute temperature.
  • Thus, an increase in pressure of an ideal gas at constant volume will result to an increase in the absolute temperature.
<h3>Boyles’s law   </h3>
  • This gas law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at constant absolute temperature.
  • Therefore, when the volume of an ideal gas is increased at constant temperature then the pressure of the gas will also increase.
<h3>Charles’s law </h3>
  • It states that the volume of a fixed mass of a gas is directly proportional to absolute temperature at constant pressure.
  • Therefore, an increase in volume of an ideal gas causes a corresponding increase in its absolute temperature and vice versa while the pressure is held constant.
<h3>Dalton’s law  </h3>
  • It is also known as the Dalton’s law of partial pressure. It states that the total pressure of a mixture of gases is always equivalent to the total sum of the partial pressures of individual component gases.
  • Partial pressure refers to the pressure of an individual gas if it occupies the same volume as the mixture of gases.
