    Engineering Amplified Tuner Circuit, Finding Resonant Frequency

    Sorry this was part of a university experiment so I don't have any values for oscilloscope impedance and the probes I used, I'm in my first year so I'm still learning, these values now seem like a good idea to ask for hahaa. I wouldn't say leads were particularly long or carelessly arranged...

    Engineering Amplified Tuner Circuit, Finding Resonant Frequency

    I am looking to find the resonant frequency of the amplified tuner circuit below The equation I have attempted to use is the f = 1/2*pi*√LC With the values for the inductance capacitance being 22pF and 47mH as I believe this is the tuner part of the circuit? The value I get by inserting these...

    Functions and Rearranging Help

    From what I understood of the question and from the previous questions is to substitute g(x) into f(x), which I think you're right, it would be written like f(g(x)) and vice versa for g(f(x)). Sorry about not making this clearer, this is my first time learning about functions. I attempted to...

    Functions and Rearranging Help

    Two functions are defined as: f(x) = 1/(-10x+14)+17 g(x) = 1/(-4x-3) Find fg(x) and gf(x) and simplify answer into form (ax+b)/(cx+d) where a,b,c and d are numbers to be found. I know it is common practice to put in some of my own attempts onto here, but I am not even getting remotely close to...

    Simple electric field strength problem

    Homework Statement How far away from a 360μC charged particle is the electric field strength 49mN/C? Homework Equations E=(8.99x10^{9} x \frac{Q}{r^{2}} The Attempt at a Solution I assumed it would be a simple case of rearranging the equation to give r=\sqrt{\frac{8.99x10^{9}xQ}{E}}...
