The capacitor in the circuit shown in (Figure 1) is charged to an initial value Q. When the switch is closed, it discharges through the resistor. It takes 1.5 seconds for the charge to drop to 12Q.
Part A
How long does it take to drop from initial charge Q to 14Q?
Express your answer to two significant figures and include the appropriate units.

A 65 g ice cube at 0 °C is placed in an insulated box that contains 8 g of steam at 200 °C. What is the equilibrium temperature reached by this closed system? Approximate the specific heat capacity of steam to be 1.5 J/g oC. All the other values can be found on the textbook. [Note: Assume that all of the steam condenses.]

Beginning with all chambers of the heart in the "relaxed" phase, describe the cardiac cycle in mammals, with systole and diastole of the atria and ventricles. For each time point in the cycle you select, state the following:
Whether the atria and ventricles are contracting or relaxing
Whether the AV valves and semilunar valves are closed or open
Whether the pressure in the atria and ventricles is high or low

Robots can be used in manufacturing and assembly
operations that require accurate,
fast, and versatile manipulation. The open-loop transfer function
of a direct-drive arm may
be approximated by
??(??)??(??) = ??(?? + 10)
??(?? + 3)(??2 + 4s + 8)
a) Determine the value of gain K when the system oscillates,
b) Calculate the roots of the closed-loop system for the K
determined in part (a).

Assume that the IS-LM-BP model is an accurate abstraction of a real economy, and use the model to describe how the macroeconomic effects of a tightening of monetary policy differ between a closed economy and an open economy. Hint: be sure to first describe the IS-LM-BP model, and then show how fiscal policy shifts the curves and the economy reached a new equilibrium.
