Horrible programming student here. I have to make an 8x8 checkerboard using python & this graphics module a professor made. As of right now this is what I have from cs1graphics import * paper = Canvas(400,400) blackSquare = Square(50, Point(75,25)) blackSquare.setFillColor('black') paper.add(blackSquare) I know I need to use the modulus operator (%) within a loop to make it so that it inserts a black square in every even square, but I can't think of how to do this shit to save my life right now. After I put down the squares in a loop I have to actually put checkers on the image, but I think after I actually understand how to loop in the black squares I'll understand how to do that. Help?

I'm having problems with this. Image is related. I've worked out the following: Boundaries: + and - 400 picometers Wavelength: 1950 picometers. With this information, how can I answer the following questions? 1) What is the approximate kinetic energy of the electron inside the well? Kinetic energy = _____eV. 2) Now consider an infinite square well potential of the same width L. When the electron is in the ground state of this infinite well, is its kinetic energy higher or lower than its kinetic energy in the ground state of the finite well? Is it higher or lower? 3) If the electron were in the ground state of an infinite square well of the same width L, what would be its kinetic energy? Its kinetic energy = _____eV. I would really appreciate if anyone can help or provide insight into this.

Am I doing this sample exam question right? The concentration of arsenic in an insecticide can be determine gravimetrically by precipitating MgNH4AsO4 (FW= 181.263) and isolating Mg2As2O7 (FW= 310.449). In one experiment, 1.951g sample of insecticide yielded 101.5mg of Mg2As2O7. Calculate the %w/w As2O3 (FW=197.842) in the insecticide. 197.842/310.449 = 63.728 % (.63728)*(.1015g)= 0.064684g As2O3 in yield. 100*(0.064684g/1.951g insecticide) = 3.32% As2O3 by weight. Is my method off; I am uncertain because I never used the FW of MgNH4AsO4

Humans = Monkey Calling a chimp an ape would be more accurate than calling it a monkey, but calling it a monkey isn't necessarily wrong. One of the defining features that differentiate Monkeys from Apes is that Monkeys have tails and apes do not. Thing is, there are monkeys out there who DON'T have tails. Example; The Barbary macaque
