If a charged particle moves a magnetic field, when it exits the field, why is the magnitude of velocity the same? Is it because of there being no work acting on the particle?
I have ucat in around 6 days. After doing well in UCAT abstract reasoning for a while. I am suddenly struggling to figure out patterns. I don't know why this is the case.
When light passes through electrons I know that some light waves are absorbed excited state etc. Since, the absorbed light is released when electrons go back to ground state, what happens to the rest of the unabsorbed light? Does it just pass through the gaps between atoms?
Is it harder to get into med school in NSW for a uni such as USYD or UNSW or is it harder to get into med for a uni like Cambridge? I know that "dah, Cambridge is better no shit," but the ucat requirements are lower and the a levels seem to be multiple choice.
I tried this ink pen out. I find it really good for writing but I am scared of the possibility of ink disappearing or anything like that. Could someone please verify whether there is nothing wrong with using these pens for the hsc?
I have some questions
Is the heat of combustion the same as enthalpy change?
What are the formula for enthalpy change and heat of combustion?
I have seen that you use q=mc(delta)t and then use delta h = q/n to find enthalpy change. I have also seen that you use this same formula for the heat...
In a chemistry practical, how would your graph look if you have multiple variables? What if you recorded number of carbon, temperature, time, colour? How would do something like this with multiple variables?
Does anyone know how I can fully prepare for curveball questions (ones where marker aims to catch you off guard) in tests? Do I just make sure I completely understand topics? Are there other things I would need to do?
