Solve part c and d
Part E only please
Can you explain part c only Where does this formula come from and from where did they get VE Why do they then use it to substitute everything
Please Help
Please just need part c answers both questions. Please just type the answer instead of hand writting.
Please answer part b
Hello, I need help with part A and Part B and Part C I just don't understand the problem I was wondering if you help me with the problems and can you label which one is which. Thank you so so so much
