    Answering MCQs on Sound Amplitude and Intensity

    No, its just that ONLY the intensity change is related to just the difference in waveforms

    What is the proof for minimizing the sum of distances on a sliced rectangle?

    Whoops... clarified what AX and XM stand for. My bad :D

    Why does observing an electron prevent it from entering a superposition?

    Hi guys, Quick question. Just started QM in class, and we discussed the double slit experiment. I am just a bit confused here. From what I understand, if just one electron is shot at the slits, it enters a superposition of states based on probabilities, and interferes with itself, resulting...

    Answering MCQs on Sound Amplitude and Intensity

    OK You are getting confused here, I think 1. If the compression and expansion are rapid, that means that the time it takes to complete a cycle of compression and expansion is small, yes? Now, I'm sure you understand that frequency is inversely proportional to period, so the frequency must be...

    What is the proof for minimizing the sum of distances on a sliced rectangle?

    Homework Statement Hi guys, I'm doing a rather long math modelling task. As part of the task, I have to investigate the following argument: There is a rectangle ABCD. It is sliced by the line EF, such that EF is parallel to AD and BC. M is the midpoint of BC. X is a point on the line...

    Will we go the the past if we could go faster than speed of light?

    IF and this is a rather big IF, you cold travel faster than light, people say you will go back in time because- Lets take a scenario. The year is 2010, yes? Let's say there is an outpost 42 light years away from Earth. If i get on a ship that can travel 42c, I will reach that outpost in 2011...

    How do I calculate the phase integral for the Bond albedo in astrophysics?

    Hi, Im doing an IB Extended essay on astrophysics, on the planning stage. My aim is to calculate the surface temperature of an extrasolar planet. I have most of the caculations done, but I am stuck on just one part - calculating the Bond albedo of the planet. I know what the geometric albedo...
