We continue our work on solving Physics problems. I'm working on my favorite text, "Fundamentals of Physics" by Halliday, Resnick and Walker 8th ed.
The first problem we solve, Chapter 1 #8, is to determing the amount of gold that is lost per second from a wedding ring over a 50 year period.
In the next problem, we are tasked to get the mass and number of atoms of an iron cube.
Problem #10 is all about determining the mass and number of atoms of a section of structural I-beam.
Problem #11 seeks to answer the question of how many molecules of water are in a pail of given mass and how many molecules of water in that pail used to be in a puddle of water in a dinosaur's claw print.
Enjoy!
