[b]1. Current and voltage graphs are shown for a capacitor circuit with ƒ=1000Hz.
What is the capacitive reactance Xc?
[b]2. I know the equation is Xc= 1/2∏ƒC to solve for capacitive reactance but where do I find C? All of our in class examples had C and ƒ given.
The...
I've been working on this problem for hours and have come up with the following thus far. Can someone let me know if I am on the right track?
Q(heat energy)=m(mass)*c(specific heat)*change of time
Q=(75 kg)*(2430 J/kg degrees C)*(2.5 degrees C)= 455,625 Joules
That portion is for the...
Thank you. I was sure it was but he has never given a problem of this difficulty so I was sure that I was reading more into it. I appreciate the confirmation. I'm going to get to work on it and hope I can figure it out. Thanks again for the quick reply.
Homework Statement
An alcohol rub can rapidly reduce an elevated body temperature in a patient. The heat energy lost by the person is due to the evaporation of alcohol. Find the number of grams of alcohol that must be evaporated from the surface of a 75 kg person to reduce the body...
