Design the component values for the series RLC bandreject filter so that the center frequency is 5 kHz and the quality factor is 5. Use a 500 nF capacitor.
Important: Please.....Plot the circuit of your design, marking the output voltage. I think it means a sinewave on an X, Y, graph plot with vo as X, and t(ms)>0 as Y. Is this possible here?

A solid, homogeneous sphere with a mass of m0, a radius of r0 and a density of ρ0 is placed in a container of water. Initially the sphere floats and the water level is marked on the side of the container. What happens to the water level, when the original sphere is replaced with a new sphere which has different physical parameters? Notation: r means the water level rises in the container, f means falls, s means stays the same.
a) r / f / s
The new sphere has a radius of r < r0 and a
density of ρ = ρ0.
The new sphere has a density of ρ = ρ0 and a mass of m
< m0.
The new sphere has a mass of m = m0 and a density of ρ
< ρ0.
b) r / f / s / r or s / f or s
The new sphere has a density of ρ > ρ0 and a mass of m = m0.
The new sphere has a density of ρ > ρ0 and a radius of r = r0.
The new sphere has a mass of m > m0 and a radius of r = r0.
c) r / f / s / r or s / f or s / r or f or s
The new sphere has a mass of m < m0 and a density of ρ > ρ0.
The new sphere has a mass of m < m0 and a radius of r > r0.
The new sphere has a radius of r < r0 and a density of ρ > ρ0.

Rising Edge Detector: The rising-edge detector is a circuit that generates a short one-clock-cycle tick when the input signal changes from 0 to 1. It is usually used to indicate the onset of a slow time-varying input signal. Moore machine state diagram for the rising-edge detector is shown in Figure 6. a. Draw the state diagram for the rising edge detector b. Adapt the Code Example 1 to implement the detector in Verilog

In order to test the functionality of a piezo sensor, we simply connect a LED with a resistance to the piezoelectric sensor. a. (5 pts) Could the LED work if we put pressure to the sensor? b. (10 pts) what is the element that we have to add to make sure that the LED will provide light ? why , justify ? Can I use Aurduino Uno IN PART b? The rectifier circuit isn't covered in my course yet. thanks
