dijnt even react to Sulfuric Acid. Where would H+ fit in the activity series you developed in question 1 (use your experi- mental data)? Can you conclusively determine its position? Why or why not? If not, what experiment could you perform to determine its position? - Would magnesium react with dilute sulfuric acid? Why or why not? If so, write a bal- anced chemical reaction?

You are taken by helicopter to an unknown location in the United States and told to walk in any direction. You walk for many months in the same direction and do not leave the United States. You make a few general observations as you travel: 1. Since you began walking, you have observed increasing numbers of mammal species. 2. Since you began walking, you have noticed a decreased diversity of tree species. 3. Since you began walking, you have heard less and less amphibian species calling at night. Based on this information, in which direction have you been traveling? east southeast west northeast

A maize producer forecasts in February 2022 that she will harvest 60,000kgs of maize by the end of the year. The price on futures contract for December 2022 maize is $7 per kg. Maize future contracts are traded in 5000 kg units. Determine the number of contracts that the maize farmers can hedge the risk she is exposed at the time of harvest in the time considering that the price of maize rise to $8 per kg and then calculate the total revenue after hedging has been done.

8. You are a research engineer investigating the forced required to fracture the clavicle (shoulder) bone before and after fixation. Since most fractures occur at the middle section of the clavicle, you have isolated this portion of the bone and are performing a tensile test on it to determine its strength. Given the geometry in Fig 1, predict the applied tensile load F at which the bone will fracture. Note: the ultimate tensile strength of cortical bone is approximately 180 MPa. • You have fixated the fractured clavicle using a plate, and wish to load this construct to failure (Fig 2). Assume that the plate will remain rigidly attached to the bone and that the plate will fail first. The critical area of the plate is at the location of fracture (section A-A), where the plate withstands all the load (i.e., no load shared with the bone). Draw a FBD of the plate-bone construct at section A-A. • Predict the applied load F when the plate fail. Note: the load is being applied through the centroid of the bone, not the plate. • During the testing the plate fails, but at region B-B. Comment on why this might have occurre
