PNG files vary in size due to a number of factors: color depth Color depth can range from 1 to 64 bits per pixel. ancillary chunks PNG supports metadata—this may be useful for editing, but unnecessary for viewing, as on websites. interlacing As each pass of the Adam7 algorithm is separately filtered, this can increase file size.

The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).
An application reading a PNG file is meant to ignore any chunks which it does not understand, [13] making APNG backwards compatible. Applications without support for the APNG extension show only the first frame, disregarding additional animation frames.

The roentgen or röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
The ESU unit of charge, franklin (Fr), also known as statcoulomb or esu charge, is therefore defined as follows: [14] two equal point charges spaced 1 centimetre apart are said to be of 1 franklin each if the electrostatic force between them is 1 dyne. Therefore, in CGS-ESU, a franklin is equal to a centimetre times square root of dyne:
He was a son of physician Harald Mathias "Mads" Gram (1875–1929) and art historian Irma Ingertha Schram (1873–1945). [1] On the paternal side he was a second cousin of Gregers Gram, nephew of Johan Fredrik Gram, grandson of Jens Gram, grandnephew of Andrea Gram, great-grandson of P. A. Munch and great-great-grandson of Jens Jensen Gram.
The gram (10 −3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram, rather than on kilogram; thus 10 3 kg is a megagram (10 6 g), not a *kilokilogram. The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg.
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
