In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 504 mL. The reserve and residual volumes of air that remain in the lungs occupy about 1955 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time. V(t) =

A bullet is fired horizontally at a stationary 7.0 kg target. The target sits on a frictionless horizontal surface and is connected to a spring on the backside of the target. The spring has a spring constant of 5000 N/m. The 11.0 g bullet is traveling horizontally at 675 m/s the moment before it strikes the target. After 1 ms, the bullet is embedded into the target and begins to oscillate. Ignore air resistance. (a) Determine the speed of the block immediately after the collision. Hint: what quantity is conserved during the collision? (b) Find the period and amplitude of the resulting simple harmonic motion. (c) Find the initial phase of the resulting simple harmonic motion. Hint: note that the block is at its equilibrium position x = 0 at t = 0. (d) On three separate graphs, plot the position vs. time, velocity vs. time, and acceleration vs. time for the system starting when the bullet is fully embedded into the target. Be sure to clearly label your axes and the scale of each graph. (e) On a single graph, plot the potential energy, kinetic energy, and total mechanical energy as a function of time for the system starting when the bullet is fully embedded into the target. Be sure to clearly label your axes and the scale of your graph.

Figure P5-1 shows a common source single transistor MOSFET amplifier utilizing an N-Channel Enhancement Mode MOSFET. The term "common source" refers to the source terminal being shared by both the input circuit and the output circuit. The parameters for the MOSFET and the supply voltage are also given. Hand Analysis P1. In terms of DC bias, determine a value for VGS to set the drain current ID to 5 mA. Also determine a value for RD to set the VDS bias to 6 V. P2. In terms of small-signal parameters, determine the transconductance gm of this amplifier as well as the voltage gain, Av. P3. If vgs is a 0.1 Vpk sinewave at a frequency of 1 kHz [ie. vgs = 0.1sin(2pift)V ] determine an expression for the output voltage vOUT as a function of time. Sketch vIN and vOUT for two complete cycles, including the DC bias for each signal. Simulation P4. Simulate the circuit of Figure P5-1 to verify your hand analysis and create a plot similar to P3 as part of your prelab. Use the virtual MOSFET model in simulation with SPICE parameters VT0 = 1.8 V and KP = 120 mA/V2. (The default values of 100um for W and L will be fine since their ratio equals unity.)

You are visiting your relatives in the Los Angeles basin on a warm day in late September. Everyone is talking about how windy and warm it is because of the Santa Ana conditions. In these conditions, winds that normally blow from west to east reverse direction, so that air comes westward over the mountains that surround Los Angeles and down into the basin. As a packet of air descends from a location in the mountains into the basin, it is compressed adiabatically, causing it to become hotter. Suddenly, the conversation stops when someone remembers you are taking physics, and everyone turns to look at you. Your uncle asks you on behalf of the rest of your family to show them a calculation that explains why the Santa Ana winds are so warm. He says that he has been to the Cajon Pass, with an elevation of 1,151 m. Every time he has been there, he has noticed strong winds, especially during Santa Ana conditions, when the air to the east and north of southern California pours westward through the passes. Your aunt is looking on her smartphone and tells you that the atmospheric pressure varies with elevation nearly linearly between sea level and low mountain altitudes, with a reduction of 12 Pa for each meter of increased elevation. Your uncle says that the air temperature was 67.3∘F when he was in the Cajon Pass. Everyone starts clamoring and begging you for a calculation that would show the temperature of the air in a Santa Ana wind on that day in the Los Angeles basin. What temperature do you calculate (in ∘F) ? (Assume air is a diatomic gas and that the Los Angeles basin has a pressure of 1 atm. ) ∘F
