How much work is done to move 3c of charge through a potential difference of 1.5v

What are similarities and differences between refraction, reflection, diffraction and absorption?

Four point charges each having charge q are located at the corners of a square having sides of length a. find symbolic expressions for the following. (a) the total electric potential at the center of the square due to the four charges (use any variable or symbol stated above along with the following as necessary: ke.) vtotal= (b) the work required to bring a fifth charge p from infinity to the center of the square (use any variable or symbol stated above along with the following as necessary: w=

Compare the patterns of the two waves shown in the image. which statement is true about these waves?
