Need to analyze the pattern and create a formula if possible out of the data below. Inputting the first column and outputting the second. 1 1 2 1 3 3 4 1 5 3 6 5 7 7 8 1 9 3 10 5 11 7 12 9 13 11 14 13 15 15 16 1 Only thing I got that is on powers of 2, it should be 1. If...

Why do I need to find the inverse laplace transform? You got any idea what the I represents in problem 1? Thanks for the help.

Hello, Anyone good source on how to do Laplace transforms? My teacher is really really bad and I have a test next week on it. I have no clue on how to do any of them. :cry: Example problems attached. Thanks for any help at all. :smile:

Need a little help with a homework problem, I don't seem to understand the theory behind this. Figure 25-23 shows four pairs of charged particles. Let V = 0 at infinity. http://www.webassign.net/hrw/25_23.gif Figure 25-23. (a) For which pairs is there another point of zero net...

Sorry I just cannot seem to any get any valid answers out of this... F=(k*Q1*Q2)/r^2 r is unknown, so for example A Q1 = +1 Q2 = -3 So wouldn't the force always be negative?

What equation is that to find that?

Figure 22-11 shows four situations in which charged particles are fixed in place on an axis. http://www.webassign.net/hrw/22_11.gif Figure 22-11. In which situations is there a point to the left of the particles where an electron will be in equilibrium? Need some help, have absolutely...

Think I would need to use air pressure of the water?

Figure 15-34 shows a dam and part of the freshwater reservoir backed up behind it. The dam is made of concrete of density 3.38 g/cm3 and has the dimensions shown on the figure. http://www.webassign.net/hrw/15_34.gif (a) The force exerted by the water pushes horizontally on the dam face...
