Thank you that makes sense now!

A guitar string has a length of 0.40m and is held fixed with both edges under tension. When it’s plucked, it oscillates with a fundamental frequency of 300 Hz. What wavelength does the wave on the string have? Is the working just meant to be L=wavelength/2 (the fundamental frequency formula)...

Hmm I’ve tried subtracting -2 from both sides, other than that I don’t know what else I could really subtract. I’m still not getting the answer, and my classmates are confused too. Sorry for all the hassle

That's really helpful, thank you very much! I've taken it a bit further for the LHS, but I'm not sure what do to for the RHS. I've attached my working:

Does anyone know how you can prove that the ratio of the longer side length to the shorter side length of a piece of paper is equal to root2?

That makes more sense now, thank you heaps

Thanks for your help!! I've now attached values for a and b

Yes sorry this is in the wrong forum! But I'm a bit confused at how 6+√2/4 squared does not give 36+2/16? I've attached a picture above now showing the values for a and b. Sorry, I probably seem like a maths noob

I'm having trouble answering these questions, especially b) and c). Any help/answers would be greatly appreciated :)

Hi everyone! I'm currently enrolling in my semester 1 subjects, but I'm not sure if I'm meant to also enrol in semester 2 subjects now. Is semester 2 meant to be done now, or later on in the year??

Hey guys! As you can probably tell by the title, is biotechnology better at UNSW or UTS? Also are subjects of similar difficulty at both uni’s? Is this a good undergraduate course to undertake in terms of employability outcomes? Thanks in advance :)

Damn that’s a shame I lost a couple of marks :( but thanks for your reply sabbabbby!
