Question 10 Give the three components of the scientific method and explain why science is conducted in this way. 1 pts The three components of the scientific method are experimentation, validation, and replication. Scientists use this method because it is standardized and systematic. When experiments are performed in the same way each time, you get valid results. The three components of the scientific method are experimentation, validation, and replication. Scientists need a systematic and standardized way to conduct research to ensure valid results and to guaranatee that the experiment can be replicated over and over again. The three components of the scientific method are creating a hypothesis, developing a research question, and collecting data. Scientists use this method to ensure they get valid results from their studies.

(1 point) Lists and tables of values are stored in an Array. (1 point) The number used to refer to a particular element of an array is called its index. (1 point) A(n) pointer makes the program more modifiable. (1 point) The process of placing the elements of an array in order is called sorting the array. (1 point) An array should be used to specify the size of an array because it determines the number of elements in the array. (1 point) Determining whether an array contains a certain key value is called searching the array. (1 point) An array that uses two indices is referred to as a multidimensional array. (1 point) The contents of a particular element of an array is called the value of that element. Pointers (7 points) (1 point) A pointer variable contains as its value the memory address. (3 points) The three values that can be used to initialize a pointer are null, address of another variable, and dynamic memory allocation. (1 point) The memory address is stored. (1 point) Naming an array, stating its type and specifying the number of elements in the array is called the declaration of the array. (1 point) The & operator returns the location in memory where its operand points. (1 point) The * operator returns the value of the object to which its operand points. (1 point) To accomplish pass-by-reference when passing a nonarray variable to a function, it is necessary to pass the address of the variable to the function.

5. Minimum Spanning Trees Consider an undirected graph, G = (V, E), with non-negative edge weights such that w(e) ? 1 \(\forall e \in E\). Suppose that you have computed a minimum spanning tree for G, as well as the shortest paths to all nodes from a particular node s ? V. Decrease the weights of all edges in the graph, such that w'(e) = w(e) - 1 \(\forall e \in E\). a. (10 pts) Does the MST of G change under this weight adjustment? Either provide an example of a graph for which it does change, or prove that it cannot change. b. (10 pts) Do the single-source shortest paths from s change? Either provide an example of a graph for which it does change, or prove that they cannot change.
