Hello all, Am I right in assuming that log(\frac{3}{5}) = \frac{log3}{log5}? Thanks,

I've arrived at \frac{3x}{x+1} = \frac{log7}{log2} I'm not sure how to progress. What should I do next? Thanks,

Homework Statement 2^{3x} = 7^{x+1} Homework Equations N/A The Attempt at a Solution 2^{3x} = 7^{x+1} I'm not entirely sure how to proceed from here. I'm assuming that the following is the right step towards the solution... (log2)(3x) = log(7)(x+1) ...but I'm not...

Thank you very much!

And would the second one be log_{10}(N^2X^3)? Thanks

I solved the second one to: log_{10}\frac{X^{0.5}}{16} Is this correct? Thanks

Homework Statement Write as a single logarithm:Homework Equations Logarithm Laws: log_a(xy) = log_a(x) + log_a(y) log_a(\frac{x}{y}) = log_a(x) - log_a(y) ___________ Problem Set: log_{10}A + log_{10}B - log_{10}C \frac{1}{2}logX - 2log4 2logN + 3logX The Attempt at a Solution I...

Hello, As I understand, a simple transformer works by using the Input AC in the primary coil to generate magnetic field in the iron core, which then generates an AC in the secondary coil. My question is: how does this process change the voltage? I've searched for answers on other websites but I...

Hello, I am having troubles ridding my research paper of this thorn in my side: It is a rather random line of dots. I have tried everything in my power to remove it, but to no avail. I am, for some odd reason, unable to highlight it. Furthermore, temporarily deleting the surrounding...

Thanks

I believe an antinode at each end, making it an open ended tube. L = \frac{n}{2}\lambda L is therefore 6 m, and velocity is therefore 7200 m s-1 Is this correct? Thanks,

Homework Statement In class a 3 m long aluminum bar was made to resonate by clamping it at a node in the centre of the bar. The frequency heard was 1200Hz. Homework Equations L = \frac{n}{4}\lambda v = f\lambda The Attempt at a Solution Knowing that L is 3, we can...

Hello, As I understand, the following formula describes the Jeans length. \lambda_j = \sqrt\frac{15k_BT}{4\pi G \mu P} Where \mu is the mass per particle. Forgive me if this question may come across as relatively stupid, I imagine that each of the particles within the cloud...

Radiation emission is triggered by compression of the materials falling into the center by gravity. The properties of the central object dictate the frequency range of this radiation. http://en.wikipedia.org/wiki/Accretion_disc

It really depends on how deep you want to dive into the Mathematics. If you're seeking a textbook that is primarily conceptual with background mathematics, then look into Conceptual Physics 11th Ed. by Paul G. Hewitt. If you're into the more mathematical aspect of physics, check out the...
