python - What is the difference between images in 'P' and

13/09/2022 · Normally, images are RGB, which means they have 3 channels, one for red, one for green and one for blue. That normally means that each pixel takes 3 bytes of storage, one for red, one for green and one for blue. If you have a P mode image, that means it is palettised. That means there is a palette with up to 256 different colours in it, and

Ask the Physicist!

If you write E=mc 2, then this is the energy of a mass which is at rest; or else it means that the mass has a different meaning from what you usually think of when it is moving with speed v, namely m=m 0 /√(1-(v 2 /c 2)) where m 0 is the mass of the particle at rest, what you usually think of as inertial mass.

Tonnage by weight, or displacement, is the weight of water displaced by a loaded vessel. This weight is expressed in metric tons. A metric ton is the weight of 1 m 3 of fresh water. Tonnage by volume is based on the English system of the measure of cubic capacity. In this system, 100 ft 3 is called a ton. It is equal to m 3.


They consist of two or more layers of different granular materials, with different densities. Usually, anthracite coal, sand, and gravel are used. The different layers combined may provide more versatile collection than a single sand layer. Because of the differences in densities, the layers stay neatly separated, even after backwashing.

Part 2: Solar Energy Reaching The Earth's Surface | ITACA

The Solar Constant. The Sun is considered to produces a constant amount of energy. At the surface of the Sun the intensity of the solar radiation is about ×10 7 W/m 2 (note that this is a power, in watts, per unit area in meters). As the Sun's rays spread out into space the radiation becomes less intense and by the time the rays reach the edge of the Earth's atmosphere they

Surface area to volume ratio of cells (video) - Khan Academy

And I'm gonna get a little bit mathy here. You don't have to know the math for the context of a biology course, but you need to know what the conclusion is that the math is going to give us. So if this is a sphere of radius r, the surface area of this sphere is going to be four pi r squared, and the volume of this sphere is going to be 4/3 pi r

The major difference in the two main grades is the amount of starting material (sodium chloride) remaining in the final product. Membrane grade caustic soda will have less than 100 ppm of the sodium chloride remaining in the product. Diaphragm grade material will have less than % sodium chloride. Several other differences can be seen in the products when the specification

The Kt/V by ionic dialysance: Interpretation limits

Correlation between recirculation rate and ionic dialysance (r=-, P<0,001)The effect of sodium load or unload on the whole body water when performing the conductivity variations has erroneously been neglected. Furthermore, it was demonstrated that different types of conductivity variations – each with specific sodium loads – differ in their results under the same conditions.
