Answer:

Energy transformation between mechanical energy and electrical energy

Explanation:

Generally, when the copper coil and the iron bar rotate in a circular direction, there is change in the magnetic flux, and as a result an electromotive force (also known as EMF) is generated. The induced electromotive force is the voltage produced due to the presence of magnetic force due to the rotation of the coil and iron bar. Thus, the energy transformation between mechanical energy and electrical energy occurs.

A sample of neon occupies a volume of 478 mL at STP. What will be the volume of the neon when the pressure is reduced to 93.3 kP
Andre45 [30]

The volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.

Explanation:

The kinetic theory of gases is mostly based on Boyle's law. From the Boyle's law, the pressure experienced by any gas molecules is inversely proportional to volume of the gas molecules. Also this inverse relation is obeyed if and only if the number of moles and temperature of the gas molecules remained constant.

So,P=\frac{1}{V}

So if there is a change in pressure then there will be inverse change in volume. That means if there is decrease in the pressure of gas molecules then there will be increase in the volume and vice versa.

So the Boyle's law is combined as P_{1} V_{1} = P_{2} V_{2}

As here the initial pressure or P_{1} is 1 atm or 101.3 kPa and the initial volume is 478 mL. Similarly, the final pressure is 93.3 kPa and the final volume will be

101.3*10^{3}*478*10^{-3}  = 93.3*10^{3} * V_{2}

V_{2} = 519 mL

So, the volume of neon when the pressure is reduced to 93.3 kPa is 519 mL.

In subtractive color mixing, like with ink on paper, when all three primary colors are combined the result is?
Maslowich

Subtractive colors mixing with all three primaries will result in black.

<h3>How are the 3 primary subtractive colors combined?</h3>

Adding all three subtractive primary color filters together will absorb all the colors of the white light spectrum as appeared below. Each filter (or pigment) absorbs its harmonizing color and transmits (diffusely reflects) the others.

Primary colors union of these three results in white. The subtractive primary colors are related to the subtraction of light: cyan, magenta, and yellow, the colors used in four-color printing, the union of these results in black.

So we can conclude that the usually used subtractive primary colors are cyan, magenta, and yellow, and if you overlap all three in a successful equal mixture.
