A single linked list is a way to store a collection of elements. Each element in a linked list is stored in the form of a node. Draw a diagram which shows a traversal algorithm in a single linked list to sum up FOUR (4) numbers: 6, -4, -2 and 20. Use the details to assist with your diagram: Show initial state Assign a proper variable for the addition operation. Show the steps by circling the current node.

Make a sketch of the vertical distribution in seawater of (a) a nutrient element; (b) an element not involved in the biological cycle. Label axes and briefly discuss the reasons for these distributions. Would you expect these distributions to be the same everywhere in the oceans? If yes, why? If no, how would they vary?

Explain what is physically meant by “Degrees of Freedom” and the “Equipartition Theorem”. a. Degrees of freedom refers to the number of rights, or freedoms, a person exercises in a given partition of time, after their yearly schedules have been equally partitioned into appropriate chunks of time. b. The Equipartition theorem states that every atom in a solid has a specific heat equal to kB/2 for every degree of freedom (or allowed kind of motion). c. The Equipartition theorem states...
