Tough Mudder is not a race. A Tough Mudder event is a personal challenge â the goal is simply to complete the course. This is why we do not time people and why we try to avoid using the word âraceâ when describing our events. This is a critical tenet of our philosophy and our pledge.ll teams that register together will be placed in the same start wave. If team members register late or as an individual and then switch to a team, Tough Mudder cannot guarantee that he/she will start at the same time as his/her team.
The number of positive charges must equal the number of negative charges so that the compound has no charge overall. When the positive ion has the same number of charges as the negative ion, it is easy to work out the formula of the compound formed. Sodium chloride contains sodium ions, Na + , and chloride ions, Cl â . As both ions have single charges, the formula is simply written as NaCl, i.e. the positive ion followed by the negative ion with no charges written. Similarly, ammonium chloride is NH 4 Cl; magnesium oxide is MgO, and so on. The fun starts when the number of charges is different, as in magnesium chloride.
1. I do not understand why the cell, while at resting potential, is negative on the inside relative to the outside of the cell. Potassium and sodium both have positive charges so why is the inside negative? Is it because there is more sodium and potassium outside the cell than inside? I read this sentence in my book and it confused me, it said During resting potential, the number of negative charges on the inside of the cell equals the number of positive on the outside. Once again why do they call the charges on the inside negative?
