An atom normally has an electron in its ground state. When a photon with the exact energy required enters the atom, the photon will be absorbed by the electron, causing it to jump to an excited state. This is known as absorption, where the electron gains energy from the photon.

a single photon has exactly the right amount of energy to cause an electron to jump from its
ground state to an excited state. there is no electron in the ground state as the photon enters the
atom. what will happen?
emission
absorption
nothing
Solution
There are certain energy levels in atom.An electron is a part of atom moving in its particular
level.So when an electron absorbs energy,it jumps to higher energy level from its
groundstate.And when it emits energy it comes back to its original state

The Vietnam War Era Discuss the range of American responses to the war. How did they change over time? How did domestic political concerns shape the country\'s response to the war? How did the war shape domestic politics in the 1960s and early 1970s? Reference: Goldfield, D. R., & In Wheeler, R. A. (2014). The American journey: A history of the United States, Combined Volume (7th ed.). Upper Saddle River, N.J.: Pearson Solution In the United States, a nationwide debate ensued over participation in the war. The government\'s official position was that it was involved in Vietnam at the request of the government of South Vietnam and was helping to repel Communist aggression from the north. Its only avowed objective was to secure a settlement that would allow the people of Vietnam to decide their own form of government. To achieve this end, it was using only carefully controlled military measures so as not to take innocent lives or bring about active participation by China or the Soviet Union. As United States involvement continued, however, Americans grew increasingly dissatisfied with their nation\'s war policy. Some, described as \"hawks,\" argued that the United States should use maximum military force to gain a quick victory. Others, called \"doves,\" argued that the conflict in Vietnam was essentially a civil war in which the United States had no right to interfere. Some of the doves demanded immediate American withdrawal, while others called for a gradual disengagement from the war. Some critics of the war charged that American use of bombers and of artillery was too indiscriminate and that many innocent civilians had perished. The revelation that United States troops in 1968 had massacred the entire population of My Lai, an enemy-held village, caused much controversy over the way in which the war was being fought. Demonstrations were held in the United States, especially in 1969 and 1970, to protest the war. As the Vietnam War progressed, it lost much support from Americans because it was clear to many that it was not justified. This caused for the country to view war as destructive, and brought about a peace movement that is mostly associated with the decade of the 1960\'s but lasted until the late 1980\'s..

I am stuck on parts E and F Exercise 1: NumberListTester.java Class NumberList implements a simple list of Integers, using an ArrayList. NumberListTester generates 10 random, positive, 2-digit ints, and adds them to the list. It then calls method printList which prints the items on the list. Run the program until you understand what it does. a. Write the body of the method printReversed, which prints the list items in reverse order. Add a statement in main to call printReversed after the call to printList. Check ______ b. Write the body of the method printEveryOther, which prints every other item on the list, beginning with the first one. In main, replace the statement that calls printReversed with one that calls printEveryOther. Check ______ c. Write the body of the method printEvens, which prints all the even-numbered ints on the list. In main, replace the statement that calls printEveryOther with one that calls printEvens. Check ______ All this printing is getting a bit tedious. Let\'s try some more fun operations. d. 0. Add a new ArrayList-of-integer instance variable called bigList to the NumberList class Add a statement to the NumberList constructor that creates an empty ArrayList object pointed to by bigList Delete the call to printEvens from main. Write the body of the method splitList, which copies all ints that are greater than or equal to 50 from aList to bigList. Add a method to the NumberList class to print bigList. Add a sequence of method calls in main to verify that the splitList method is working correctly. I.e., after calling splitList, call again the method that prints the original list and then call the method you wrote in step 4 to print the bigList. Check _____ E. Add a method insert to the NumberList class that takes two parameters of type int. The first parameter is the index at which to insert a new number into the list, and the second is the number to be inserted. E.g., if the first param is 4 and the second is 37, then 37 will be inserted at index 4 in aList (i.e., as the new 5th list element). The number inserted does not replace the number currently at that position, but is inserted just before it. Hint: The ArrayList class has a method that does exactly this. Call that method from your insert method. Now add statements to main to allow the user to specify the number to insert and the position at which to insert it. Then, after inserting the new number, print the updated list. Check _____ F. Finally, add code to your insert method that will assure that an IndexOutOfBoundsException cannot be thrown. I.e., your insert method should just print an appropriate error message if the first parameter --- the index at which to insert the new Integer --- is illegal. Hint: What are the legal indices for an ArrayList? What is the smallest? What is the largest? What about the special case of inserting a new value at the end of the list? Try it!

How does differ from evolution systematic? Only cladistics traces evolution relationship and construct classifies that reflects these relationship. Only evolution systematic recognizes that organisms must be compared using specific characters. Only cladistics rigorously defines the kinds of homologies that yields the most useful information. Only clasdictics uses homologous traits to trace to apply evolution relationship Why is the paleospcc.es concept more difficult to apply to organisms than the biological and the ecological species concepts? Because reproductive isolation cannot be studied directly Because ecological distinction are difficult to impossible be past environments Because neither exclusive mating nor ecological separators are usually accessible us fossil specimens. Because homologous Waits are rarely expressed In fossil specimens Parapatric specification is characterized by? Complete reproductive isolation of two populations Partial reproductive isolation of two populations. No reproductive isolation of two populations. Complete ecologic niche separation of two species What is the age of the oldest known fossil found on Earth 3.8 billion years. 3.5 billion years. 2 billion years. 520 million years. Taphonomy is the study of: What happens to organic matter after death. How bones mineralize during fossilization. The rules of classification. Ancestral traits In closely related species. When general and specialized traits of organisms are considered in evolution it is important to recognize that only a generalized ancestor can profit from the flexible evolutionary basis for rapid diversification Which of the following animals is an appropriate example for a highly specialized placental mammal that is structurally to a narrow, rodent/woodpecker-like econiche: The duck-billed platypus. The wallaby. The white-tailed deer. The aye-aye of Madagascar. Solution 41. B. Partial reproductive isolation of two populations. Parapatric speciation occurs when populations are separated not by a geographical barrier, such as a body of water, but by an extreme change in habitat. While populations in these areas may interbreed, they often develop distinct characteristics and lifestyles. Reproductive isolation in these cases is not geographic but rather temporal or behavioral. 42. B. 3.5 billion years. The oldest known fossils, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. 43. B. How bones mineralize during fossilization. Taphonomy is the branch of palaeontology that deals with the processes of fossilization. 44. C. The aye aye of Madagascar. From an ecological point of view the aye-aye fills the niche of a woodpecker, as it is capable of penetrating wood to extract the invertebrates within..

Discuss the major capabilities of DBMS and why is a relational DBMS so powerful? Solution DBMS :- DBMS is a software or tool which can be used for managing and maintaining the data within the database. Major Capabilities of DBMS :- 1.Data Storage 2.Data Retrieval 3.Data Update 4.Security 5.Data Independence Explanation :- Generally a person has to work with huge amount of information everyday. Inorder to interact with the large amount of data we need a system where we can store, manipulate, security, sharing the information all over the world. It is a core reason the industries are maintaining database management tools. A relational DBMS is so powerful. Because :- * In RDBMS model the data will be stored in the form of tabular format. where as table is nothing but a collection of rows and columns. * RDBMS model will provide high level security by using authentication and autherisation. * RDBMS maintains accurate and consistency of the data with the help of data integrity mechanism. * RDBMS supports the data manipulations by using DML commands. * RDBMS provides faster rate retrieving the data by using index mechanism..
