For the first part of the question we note that the resistors are in series, this means we can simply add together the resistance, giving a value of: 15 ohms
For the second part we ...
Using the knowledge that the moments are balanced, we can create an equation to calculate the distance John is from the pivot:
600N1.50m = 200N(distance) (600/200)*1.5 = di...
The speed of a wave is given by "Frequency*Wavelength=Wave speed". Hence, the speed is 340. With the units of speed being m/s
Total resistance in a circuit depends on whether the resistors are in series or parallel since this determines which equation is to be used.In series, resistors are essentially lined up next to each other...
