1. The problem statement, all variables and given/known data A bird stands on a DC electric transmission line carrying 2800A. The line has 2.5 x 10^-5 ohms resistance per meter, and the bird's feet are 4.0 cm apart. What is the potential difference between the bird's feet? 2. Relevant equations I wish I knew 3. The attempt at a solution Alright so since the resistance is 2.5 x 10^-5 per meter, I found that the resistance is .000001 ohms between the bird's feet. Since the current is 2800A, I used the equation V=IR and got .0028V. Is this correct or is the problem asking for something else? Also, there is another problem I have 1. The problem statement, all variables and given/known data Part A: An electron in the picture tube of a television is accelerated from rest through a potential difference Vb-Va= 3000v. What is the change in electric Potential energy of the electron? Part B: What is the speed of the electron as a result of this acceleration? 2. Relevant equations W=q(Vb-Va) 3. The attempt at a solution I solved part A using the equation stated above and got 4.8 x10^-16 The part that I need help with is Part B. What equation should I use to find the speed?
