Describe the two theories on the emergence of light by Rene Descartes and Sir Isaac Newton​

Answers

Answer 1

Explanation:

Isaac Newton argued that the geometric nature of reflection and refraction of light could only be explained if light were made of particles, referred to as corpuscles because waves do not tend to travel in straight lines. Newton sought to disprove Christiaan Huygens' theory that light was made of waves.

Answer:

the causes of World War II:

The major causes of World War II were numerous. They include the impact of the Treaty of Versailles following WWI, the worldwide economic depression, failure of appeasement, the rise of militarism in Germany and Japan, and the failure of the League of Nations. ... Then, on September 1, 1939, German troops invaded Poland.

U.S. response during the early years of World War II:

U.S. response during the early years of World War II- We tried to remain neutral while supplying weapons to Britain and France. ... The effect of the attack on Pearl Harbor was that it forced the U.S. into a war with Japan and made us use an atomic bomb to defeat the enemy.

the catalysts that brought the United States into formal involvement in the war:

The catalysts that brought the United States into formal involvement in the war The catalysts that brought the United States into formal involvement in the war was the Japanese attack on Pearl Harbor.

the causes and consequences of the attack on Pearl Harbor:

The Japanese attack on Pearl Harbor caused about 2400 dead, almost 200 planes destroyed and 8 battleships destroyed or damaged. The long-term effect of Pearl Harbor was that it brought in the US to the war. It pushed Americans into the war that they were avoiding for so long.

the causes and consequences of the D-Day invasion:

What happened on D-Day? The attack began when Allied planes and warships bombarded German positions along the coastline. This was to damage the defences making it easier for the troops to get ashore. At the same time, planes and gliders dropped tens of thousands of allied soldiers behind the German defences. D-Day was the beginning of the end for not only the Germans but Hitler most of all. D-Day forced the Germans to fight a two front war again just as they had in WWI. Yet again the Germans could not handle war on both sides of them.

the strategy of the Japanese and the U.S. military in the Pacific Theater:

Leapfrogging, also known as island hopping, was a military strategy employed by the Allies in the Pacific War against the Empire of Japan and the Axis powers during World War II.

the ways new military technology enabled the United States to fight successfully on multiple fronts:

the ways new military technology enabled the United States to fight successfully on multiple fronts. There were many: The Blitzkrieg tactical warfare (lighting war)Radar, and it's underwater cousin, sonar, had a significant impact in countless military battles. There was also the atomic bomb. That is just naming a few.

the impact of the Holocaust during World War II on Jews as well as other groups:

The Jews were inslaved and some even put to death, and they were tortured. The other groups also hid a lot of Jews, so a lot of them were put to death.

reasons for the U.S. response to the Holocaust before, during, and after World War II:

Before, they didnt know about it for a while, but when they did they came to help. During, they fought for their freedom. After, they went back.

the social, political, and economic changes experienced by Americans on the homefront during World War II:

Food, gas and clothing were rationed. Communities conducted scrap metal drives. To help build the armaments necessary to win the war, women found employment as electricians, welders and riveters in defense plants. Japanese Americans had their rights as citizens stripped from them.

the use of atomic weapons during World War II and the aftermath of the bombings:

The bombs caused a lot of damage and deaths, and atomic weapons used were things like bombs and explosives.

the consequences of World War II on the United States and the world:

America's involvement in World War II had a significant impact on the economy and workforce of the United States. ... Our involvement in the war soon changed that rate. American factories were retooled to produce goods to support the war effort and almost overnight the unemployment rate dropped to around 10%.

the end of the war in Europe compared to the end of the war in the Pacific:

The war in Europe was largely a land war, with the exception of submarine warfare in the Mediterranean and around the British Isles. ... The war in the Pacific was largely fought over water with key islands such as Midway and Iwo Jima being flashpoints.

How did Mansa Musa's policies influence the Kingdom of Mali?
A. They led to an increase in trade.
B. They forced Christians to flee from Africa.
C. They made him the leader of the Islamic world.
D. They caused an economic decline.

Answers

Mansa Musa's policies had a significant influence on the Kingdom of Mali as They led to an increase in trade. Option A.

Mansa Musa's policies had a significant influence on the Kingdom of Mali, particularly in terms of trade. Mansa Musa, who reigned from 1312 to 1337, was known for his successful efforts to expand Mali's influence and wealth. One of his most famous achievements was his pilgrimage to Mecca in 1324, during which he embarked on a journey that showcased the immense wealth of the Mali Empire.

During his pilgrimage, Mansa Musa brought a large entourage that included soldiers, scholars, and merchants. He also carried a considerable amount of gold, which he distributed generously along the way. This lavish display of wealth caught the attention of various traders and rulers in the regions he passed through, and it created a significant economic impact.

Mansa Musa's journey to Mecca exposed the wealth and resources of the Kingdom of Mali to the wider Islamic world. As a result, it led to an increase in trade, as merchants and traders were attracted to the region's abundant resources, including gold, salt, and other valuable commodities. The increased trade brought prosperity to Mali and contributed to its economic growth.

Therefore, option A is the most accurate statement regarding the influence of Mansa Musa's policies on the Kingdom of Mali.

Answers

Answer:

Evidence-based policymaking is relevant for all levels of government. State agencies play an important role in creating and using evidence as they implement policies and collect data while operating programs. Often, effective evidence-based policymaking requires a healthy partnership between the federal government and states, with some federal programs relying on state-level actions and support. For example, many social services and environmental programs are operated by states on behalf of the federal government, with states collecting data, making eligibility determinations, and conducting enforcement activities. The data collected through these normal operations can be analyzed to ensure programs operate as intended. The federal government can also help support and enable activities at the state-level. In some cases, data may be needed to analyze activities conducted across many states and to generate comparisons for determining what implementation strategies are most effective for a given program.

Answer:The skeletal system makes up the framework of the body and allows us to move when our muscles contract. It stores minerals (e.g. calcium, phosphorous) and releases them into the body when they are needed. The skeletal system also protects internal organs and produces blood cells. Bones (e.g., skull, vertebrae)

Bones provide calcium that is essential for the proper functioning of the nervous system.

The skull protects the brain from injury.

The vertebrae protect the spinal cord from injury.

Sensory receptors in joints between bones send signals about body position to the brain.

The brain regulates the position of bones by controlling muscles.

Cardiovascular System

The cardiovascular system delivers oxygen, hormones, nutrients and white blood cells around the body by pumping blood, and it removes waste products. Heart, blood vessels

Endothelial cells maintain the blood-brain barrier.

Baroreceptors send information to the brain about blood pressure.

Cerebrospinal fluid drains into the venous blood supply.

The brain regulates heart rate and blood pressure.

Muscular System

Different types of muscles enable motion, generate heat to maintain body temperature, move food through digestive tract and contract the heart. Muscles (smooth, skeletal and cardiac muscles)

Receptors in muscles provide the brain with information about body position and movement.

The brain controls the contraction of skeletal muscle.

The nervous system regulates the speed at which food moves through the digestive tract.

Endocrine System

The endocrine system secretes hormones into blood and other body fluids. These chemicals are important for metabolism, growth, water and mineral balance, and the response to stress. Pineal body, pituitary gland, hypothalamus, thyroid, parathyroid, heart, adrenal gland, kidney, pancreas, stomach, intestines, ovary

Hormones provide feedback to the brain to affect neural processing.

Reproductive hormones affect the development of the nervous system.

The hypothalamus controls the pituitary gland and other endocrine glands.

Lymphatic System

The lymphatic system protects the body from infection. Adenoid, tonsils, thymus, lymph nodes, spleen

The brain can stimulate defense mechanisms against infection.

Respiratory System

The respiratory system supplies oxygen to the blood and removes carbon dioxide. Lungs, larynx, pharynx, trachea, bronchi

The brain monitors respiratory volume and blood gas levels.

The brain regulates respiratory rate.

Digestive System

The digestive system stores and digests foods, transfers nutrients to the body, eliminates waste and absorbs water. Stomach, esophagus, salivary glands, liver, gallbladder, pancreas, intestines

Digestive processes provide the building blocks for some neurotransmitters.

The autonomic nervous system controls the tone of the digestive tract.

The brain controls drinking and feeding behavior.

The brain controls muscles for eating and elimination.

The digestive system sends sensory information to the brain.

Reproductive System

The reproductive system is responsible for producing new life. Testes, vas deferens, prostate gland, ovary, fallopian tubes, uterus, cervix

Reproductive hormones affect brain development and sexual behavior.

The brain controls mating behavior.

Urinary System

The urinary system eliminates waste products and maintains water balance and chemical balance. Bladder, urethra, kidney

The bladder sends sensory information to the brain.

The brain controls urination.

Integumentary System

The integumentary system reduces water loss, contains receptors that respond to touch, regulates body temperature, and protects the inside of the body from damage. Skin, hair

Receptors in skin send sensory information to the brain.

Answers

Answer:

After the end of the Civil War, during the Reconstruction process, African Americans were recognized a whole series of civil and political rights that equated them (in theory) with the whites. Now, with the end of Reconstruction, these rights were suppressed by the southern states of the nation, through the process of segregation and the application of the theory of "separate but equal". Thus, different limitations such as literacy tests or poll taxes were applied to prevent black people from voting. Finally, after years of mobilizations and claims framed in the Civil Rights Movement, in 1965 the right to vote was recognized for all African Americans through the Civil Rights Act and the Voting Rights Act.
