Darrius and Monte decided to enter the annual Strong Man Competition. One of the categories they will have to compete in is the Truck Pull, in which they will have to strap a harness on themselves, attach it to a truck, and pull the truck by using the sheer force of their bodies moving forward. Since they are only in the training phase, they decide to each start by pulling a small car, but no matter how hard they try, the car will not move. What type of friction does this scenario illustrate?

Acompound machine is also called a machine. a. force b. simple c. complex d. directional

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

Can you match these to the correct definition
