Ho Idlxf 4π 72 dB This problem checks your understanding of the term in the equation for the magnetic field due to a small "piece" of current, Consider a small piece of current (perhaps there's a wire) at location $ whose coordinates are (6 m, 2 m, 10 m). We would like to find the magnetic field at location P whose coordinates are (2 m, 5 m, 2 m). The term " is the distance between point S and point P. What is its value, in meters?
||| INT A 20-cm-long, zero-resistance wire is pulled outward, on zero-resistance rails, at a steady speed of 10 m/s in a 0.10 T magnetic field. (See Figure P25.630.) On the opposite side, a 1.0 carbon resistor completes the circuit by connecting the two rails. The mass of the resistor is 50 mg. a. What is the induced current in the circuit? b.

What inductance must be connected to a 20 pF capacitor in an oscillator capable of generating 590 nm (i.e., visible) electromagnetic waves? Number i Units
Part A You've recently read about a chemical laser that generates a 20.0-cm-diameter, 24.0 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20.0-cm- What speed would such a block have if pushed horizontally 95.0 m along a frictionless track by such a laser? Express your answer with the appropriate units. diameter, 98.0 kg, perfectly absorbing block. HA ? Value Units
