1. Piezoelectric materials are often used as sensor materials because they transform mechanical deformation to electrical charge. Figure 1 shows an electric circuit of a piezoelectric sensor. The piezoelectric material is modeled as a current source in parallel with a capacitor. The resistance models the impedance of an amplifier. The goal is to make the output voltage v(t) proportional to the input charge q(t), so that we can use the voltage v(t) to measure the charge q(t). The ODE governing the input and output is dv RC +v=R- dt Ddq dt (1) where q(t) is the input and v(t) is the output. (a) Determine the frequency response function G(w).

#1. Hello can you find Ir1,ir2 ,Ireland, rt and it and pt. Thank you please show me how to do my homework
When a system is expanding and doing work, part of the work done is used to overcome the atmospheric pressure, and thus Wsurr represents a loss. When a system is compressed, however, the atmospheric pressure helps the compression process, and thus Wsurr represents a gain.

2. Consider a simple AM radio consisting of a tunable L-C circuit. The input is the voltage received by the antenna v,(t), and the output is the voltage vo(t) to an amplifier. The ODE governing the circuit is 4C- d²vo dt² +2× 10 4 dvo dt +2x10¹vo = 2 × 10 4 dus +1 × 10 2vx dt (2) where C is capacitance of the variable capacitor to select stations.

2. Figure 1 shows a sensor consists of a core, an armature and a variable air gap. The core with 3.0 cm depth and 10000 relative permeability has 200 coil turns. On the other hand, the armature is a steel plate of thickness 0.2 cm and has similar relative permeability with the core. Assuming the relative permeability of air is unity and the permeability of free space is equal to 4x x 10-7 H.m, calculate the inductance of the sensor for air gaps of 0 mm and 2 mm.
