3. [7pts] With the switch closed, the circuit eventually reaches steady state. Use the loop and node rules to calculate the steady state charge on the capacitor. A battery with potential emf is connected with three resistors (resistances R, 2R, and 4R), a ca- pacitor (capacitance C), and a switch to close and open the circuit as shown. Assume all of the con- emf necting wires have zero resistance. 2R w 4R Έ R switch 1. [6pts] Write down the the node rule relating the currents IR, I2R, and I4R flowing through the three resistors, and all the loop rules that apply to this circuit when the switch is closed. Use the variable Q for the magnitude of the charge on the capacitor plates. 2. [7pts] Suppose that initially the capacitor is uncharged, and the switch is open. Using the equations you found above, find the current IR through the resistor with resistance R observed immediately after closing the switch.

Select all correct answers (i.e. more than one answer may be correct). Which of the following statements about EMG recorded from a single person are true? For a sustained, submaximal isometric muscle force, the EMG activity will increase with fatigue. For isometric muscle force generation under different force magnitudes, muscle EMG will be smaller for small forces (e.g. 50% max effort), and muscle EMG will be larger for large forces (e.g. 100% max effort). Assume no fatigue.
