what about the rest of the problem. I'm having a lot of problems grasping the concept of E-fields and stuff.

Two charges, one -q and one +q are located at x=-a and x=+a, respectively. Use a spreadsheet to plot the electric field along the x asix. Part of this problem is choosing a reasonable range for the plot. How do I go about doing this?

A 30.0 m steel wire and a 20.0 m copper wire, both with 1.00-mm diameters are connected end to end and stretched to a tension of 150 N. How long does it take a transverse wave to travel the entire length of the two wires? I really don't need an answer but rather something to get me going.

A sinusoidal wave is travelingh along a rope. The oscillator that generates the wave completes 40.0 vibrations in 30.0s. Also, a given maximum travels 425cm along the rope in 10.0s. What is the wavelength?

thanks, that's exactly the info that i needed to get going.

I really just need help getting started... What additional force is necessary to hold a water hose stationary after the water flow is turned on, if the discharge rate is .6 kg/sec with a speed of 25 m/s? Thanks in advance..
