    Calculate the wave speed in each string

    In Fig. 17-30a, string 1 has a linear density of 2.30 g/m, and string 2 has a linear density of 4.10 g/m. They are under tension owing to the hanging block of mass M = 500 g. (a) Calculate the wave speed in each string. m/s (speed in string 1) m/s (speed in string 2) (b) The block...

    Calculating First Meeting Point of Pulses in a Stretched Wire

    Hi, I am having difficulty understanding this question: A wire 5.0 m long and having a mass of 130 g is stretched under a tension of 220 N. If two pulses, separated in time by 30.0 ms, are generated, one at each end of the wire, where will the pulses first meet? m (distance from the left...

    Electric Fields and vertical deflection

    I was also wondering if anyone could help: 1. Two charges, -15 and +4.4 µC, are fixed in place and separated by 3.0 m. (a) At what spot along a line through the charges is the net electric field zero? Locate this spot relative to the positive charge. Let the positive charge be at x = 0 and the...

    Electric Fields and vertical deflection

    Yes, but I still can't get the vertical distance for some reason knowing that the time is 8.421E-10 and using F=ma with a=(-1.6E-13)/(9.1E-31)=-1.756E17.

    Electric Fields and vertical deflection

    We usually go over stuff after getting the assignments, so I have no clue how to start this question. Figure 23N-14 shows the deflection-plate system of a conventional TV tube. The length of the plates is 3.2 cm and the electric field between the two plates is 10^6 N/C (vertically up). If the...
