The final answer is r = 43m that my professor gave me, but I
dont know how he got it. Show me steps to solve this question
How do I solve 6.57 = 2 + log [0.125]/[H3PO4]? I know the answer is supposed to be [H3PO4] = 3.38X10^-6 M, but how do I get there? PLEASE SHOW ALL STEPS
How am I supposed to know what C is for this problem? I have read in the solution manual that C = 0.449 J/goC but I don't understand how to get that number if it's not given to me in the word problem. I know how to solve the problem to get the answer for the final temp, I just don'r understand how to get the 0.449 J/goC. The word problem is: An iron nail with a mass of 12...
Please please READ MY QUESTION.
-----------------------------------*
I have the answer.
I don't know where the circled parts are coming
from. Can you explain the distribution and how we are getting the
CIRCLED/ARROWED VALUES? I'm posting this question three
times.
please solve it don't right the steps becasue i don't know how to
do it that my second time send it. Thanks in advance

I don't know why the answer is
wrong, I got K(final) = 1.1072x10^-15 J and K(initial) =
1.4576x10^-15J, with the work energy theorm I got q=(Kf-Ki)/(Vi-Vf)
= +5.48x10^-18 C
Your answer is partially correct. Try again. A moving particle encounters an external electric field that decreases its kinetic energy from 9100 eV to 6990 eV as the particle moves from position A to position B. The electric potential at A is-41.0 V, and that at B is +23.0 V. Determine...
Please Disregard my handwritten solutions. I solved it, however
I don't know if my answer is correct or not.
Pease solve it step by step and legible handwriting.
