Homework Statement
A uniform sphere of radius a is placed at the lowest point of a fixed thin
hemispherical bowl of radius b > a. The sphere is the slightly displaced and
released with zero initial velocity such that it rolls without slipping on the inner
surface of the bowl. By...
Hi, I've understood the basics of an RLC circuit but it seems that when actually putting them into practice I'm advised to put an additional resistor in before the (RL) and C that are in parallel with one another with no explanation. What's the purpose of this resistor and what does altering its...
Oh dear, yes of course. Thank you. I'd decided the slowly part meant I could ignore the motion of the piston, but obviously that's not the case. (This isn't a homework question, just my own exam preparation)
So the work done on the gas by the piston is proportional to the displacement squared...
Homework Statement
Perfect gas in an enclosed cylinder, the thermal capcity of the components in the cylinder and piston are small and they are perfect thermal insulators. The piston is pushed in slowly and allowed to return to its original position slowly.
How does the Temperature vary with...
