I am totally lost with physics and need all the help I can get I dont know what formula to use and it seem like with any problem I used the wrong formula but some how the amswers are correct sometimes. Any help would be greatly appreciated. Thanks, Lissa

Question:
In a pacemaker, a pulse is delivered to the heart 81 times aminute.The capacitor that controls this pulsing ratedischarges through aresistance of 1.8*10^6 ohm. One pulse isdelivered everytime thefully charged capacitor loses 63.2% of itsoriginal charge. What isthe Capacitance of the Capacitor?

The equation that you suggest is q= q_o e^(-t/RC)

t =.7404
R=1.8*10^6

So to solve I take the (ln q/q_o) and I get 1.44

So the Capacitance should equal -t/(1.8*10^6)(1.44)

The corect answer in the back of the book is 4.1*10^-7 but whenIwork out the problem I keep getting 2.86*10^-7.

Could you please check the math on this problem and let me know ifIam making a mistake or if the answer given is incorrect?

Thank you so much for your time and help!


I need a step by step answer on how to solve problem 11.25 Iattached the question from the book and answers that the back ofthe book gave me but I need someone to explain how and why you getthose answers, thanks.

on part b I understand the Δstot=0, but how does therule Δl=+/- 1 work?

-do the states on left collum (1s2, 1s2s, 1s3s) allhave l=0 and the ones on right collum (1s2p, 1s3p) all have a l=1then?

in part c What does mestastable mean, and how do you know whenit is?

-Does mestastable mean it has no where else to decay or what,and if so then why isn't 1s2 mestastable, is it becauseit's not an excited level, and how do you decide which ones areexcited levels?
