Questions

Michelаngelо’s Dаvid stаtue is 18½ feet tall, including the base. Based оn the fact that the density оf marble stone is 160 lbs/cubic foot, a person could estimate that the statue weighs about 5,300. lbs, or 2,325 kg (1 kg is 1,000 g). Marble has a chemical formula of CaCO3 (calcium carbonate). In the 1750s, Joseph Black found that if calcium carbonate is heated to a temperature of over 825°C, it decomposes and releases “fixed air,” which is CO2, and produces lime (not the citrus fruit but a solid, white chemical compound). The chemical formula of lime is CaO. Write out a balanced equation for the reaction that shows CaCO3 (calcium carbonate) reacting to produce CaO (lime) and CO2 (carbon dioxide).  BYU-Approved David Statue Note: Show all work for this question for full credit.

Yоu аre given а cоllectiоn of directed, weighted edges thаt represent a graph. Each edge connects two nodes and has a weight associated with it. An edge is defined using the following class: public class Edge {    public E src;    public E dest;    public int weight;} Implement a method with the signature: public Queue findGreedyPath(List edgeList, E src, E dest) that does the following: Given src and dest nodes, return a Queue of Edges that represents a path from src to dest in which each edge is the lightest (lowest weight) edge coming out of each node in the path that does not result in a cycle, i.e. does not go back to a node that is already in the path. For instance, let's say you have the following graph and have "A" as the src and "E" as the dest:     The method should work as follows: We start at the src, which is A. The lightest edge coming out of A is the one to C, which has a weight of 4, so we would add that Edge to the Queue; note that although there is an edge to our dest node, we don't select that one since it's not the lightest Now we're at C. There is only one edge coming out of it, which goes to D, so we add that Edge to the Queue. Now we're at D. The lightest edge is the one going to A, but we have already visited A, so we look for the next lightest edge, which is the one going to E, and we add that Edge to the Queue. We're at E, which is the dest, so we're done, we return the Queue containing the three Edge objects. You may assume that: the graph is completely connected, i.e. every node is reachable from every other node, which means that every node has at least one Edge. edge weights are always positive all edges coming out of a node have distinct weights, i.e. there will never be a tie for the lightest edge you do not need to check for null inputs values or any other error conditions in your implementation Last, you may also assume that a solution always exists for every src-dest pair in the graph; you do not need to worry about the case when all of a node's outgoing edges go to nodes that are already in the path. This question will be graded by a member of the instruction staff; partial credit is possible. It is okay if there are slight compilation errors in your code, but you will lose points for using the wrong methods Java classes that you use. You may consult https://docs.oracle.com/javase/8/docs/api to help find the right methods.
