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...

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...

Am I on the right track by substituting one equation into the other and and I just need to look back at my simplifying or am I going about this completely wrong?

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...

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...

Could it be a case of the answer given is not correct?

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}}...

Ah thank you very much for pointing that out! Much appreciated!

Homework Statement A certain fluid of mass 1kg undergoes a cycle of processes in a piston and cylinder device as follows: Process A-B: 70kJ of work done on the fluid. 35kJ of heat rejected to surroundings Process B-C: 50kJ of heat transferred to the fluid. No change in internal energy of...

Homework Statement Hi again guys, been stuck on this problem for a while now, thought it would be a simple bumping in some values in a given equation question but I can't get the correct answer :confused: Heres the problem: What is the inductance of a 600 turn coil wound on a core of cross...

Ah I see where I have gone wrong! Was just a matter of reading the question properly :rolleyes:Thanks a lot guys!

Homework Statement A rectangular wire loop, 24mm by 36mm, is placed in a magnetic field. The flux density perpendicular to the loop is decreasing in magnitude at a rate of 0.2Wb/m^{2}/s. Calculate the induced emf around the loop. Homework Equations The problem is I don't know which...

Ah I see! It would be 10^-12?

Would this be correct: For area in μm = 1μm^2 and area in m = 10^-6m^2 Thanks for replying!

Homework Statement Hi guys this isn't so much a coursework or homework help problem but figured this would be a sensible place to post my question. Basically I got back an assignment I had recently completed from my tutor and I had been marked down for some errors in regard to the orders of...
