A long solenoid with closely spaced turns carries electric current. Does each turn of wire exert (a) an attractive force on the next adjacent turn, (b) a repulsive force on the next adjacent turn, (c) zero force on the next adjacent turn, or (d) either an attractive or a repulsive force on the next turn, depending on the direction of current in the solenoid?
Notes for Week 2 Physics 1 Instantaneous Velocity: Examples: 1. A jet engine moves along an experimental track (which we call the x axis). We will treat the engine as if it were a particle. Its position as a function of time is given by the 2 2 equation x = At + B, where A = 2.10m/s and B = 2.80m. (a) Determine the average velocity during this time interval. (b) Determine the displacement of the engine during the time interval from t1= 3.00s to t2= 5.00s. (c) Determine the magnitude of the instantaneous velocity at t = 5.00s. Solution: (a) In physics, the first thing you do when you have a question is see what the question is asking yo
