Answer:Alexander Graham Bell, best known for his invention of the phonephone, revolutionized communication as we all realize it. His interest in sound technology was deep-rooted and personal, as both his wife and mother were deaf. While there’s some controversy over whether Bell was truth pioneer of the phonephone, he secured exclusive rights to the technology and launched the Bell public-service corporation in 1877. Ultimately, the talented scientist held quite 18 patents for his inventions and add communications.

Birthplace

Alexander Graham Bell was born in Edinburgh, Scotland, on March 3, 1847. Bell’s father was a professor of speech elocution at the University of Edinburgh and his mother, despite being deaf, was an accomplished pianist.

Young Alexander was an intellectually curious child who studied piano and began inventing things at an early age. Both of his brothers died from tuberculosis by the time Bell was in his early twenties.

Education

Initially, Bell’s education consisted of homeschooling. Bell didn’t excel academically, but he was an issue solver from an early age.

When he was just 12, the young Alexander invented a tool with rotating paddles and nail brushes that may quickly remove husks from wheat grain to help improve a farming process. At age 16, Bell began studying the mechanics of speech.

He went on to attend Royal highschool and thus the University of Edinburgh. In 1870, Bell, along with his family, moved to Canada. the next year, he settled within the u. s..

While within the U.S., Bell implemented a system his father developed to point out deaf children called “visible speech” — a gaggle of symbols that represented speech sounds.

In 1872, he opened the school of Vocal Physiology and Mechanics of Speech in Boston, where deaf people were taught to speak. At age 26, the budding inventor became Professor of Vocal Physiology and Elocution at the Boston University School of Oratory, while he didn’t have a university degree.

While teaching, Bell met Mabel Hubbard, a deaf student. The couple married on July 11, 1877. They went on to have four children, including two sons who died as infants.

Telephone

In 1871, Bell started workinh on the harmonic telegraph — a tool that allowed multiple messages to be transmitted over a wire at the identical time. While trying to perfect this technology, which was backed by a bunch of investors, Bell became preoccupied with finding how to transmit human phonation wires.

By 1875, Bell, with the help of his partner Thomas Watson, had come up with a straightforward receiver that may turn electricity into sound.

Other scientists, including Antonio Meucci and Elisha Gray, were functioning on similar technologies, and there’s some debate over who should be credited with the invention of the phonephone. It’s said that Bell raced to the office to be the first to secure the rights to the invention.

On March 7, 1876, Bell was granted his telephone patent. some days later, he made the first-ever telephone to Watson, allegedly uttering the now-famous phrase, “Mr. Watson, come here. I want you.”

By 1877, the Bell utility, which today is known as AT&T, was created. In 1915, Bell made the first transcontinental telephony to Watson from the massive apple to city

What made it so hard for Hinduism to spread?
larisa [96]

<em>There is no place for a convert in Hindu society, which is made up of castes, each of which is a closed corporation. As a result, the caste system has hindered Hindus from growing and absorbing other religious groups. Evangelism was not a priority for Hinduism and Judaism in the past. Both of these religions are more culturally and ethnically based. The missionary enthusiasm was missing, just as it was in Europe's pagan faiths and China's religions. Nothing in the holy writings makes it the followers' responsibility to disseminate the faith.</em>

How was Afghanistan caught in the middle of the cold war between the United States and the Soviet Union?
dusya [7]

Answer: Leaders: The leaders of Afghanistan during the war included General Secretary Babrak Karmal and President Mohammad Najibullah. Soviet Union leaders included Leonid Brezhnev and Mikhail Gorbachev. Leaders from the Mujahideen included Ahmad Shah Massoud (nicknamed the Lion of Panjshir) and Abdul Haq. US Presidents during this time were Jimmy Carter and Ronald Reagan.

Explanation:

The Soviet Afghanistan War was fought between Afghanistan rebels called the Mujahideen and the Soviet supported Afghanistan government. The United States supported the Afghanistan rebels in order to try and overthrow the communist government and to prevent the spread of communism.

Before the War As one of its bordering neighbors, the Soviet Union had a long history of supporting and providing aid to Afghanistan. On April 27, 1978 a Soviet supported communist government took over the country. The new government was called the Democratic Republic of Afghanistan (DRA). Many of the Afghanistan people did not like the new communist government, primarily because many of the laws went against their Muslim religion. They began to rebel against the current government. The rebels called themselves the Mujahideen. In September of 1979, events in Afghanistan became more unstable when Afghan leader Hafizullah Amin had the current president killed and took control of the communist government. The War Begins The leaders of the Soviet Union became concerned that President Amin was having discussions with the United States. On December 24, 1979 the Soviet Union invaded Afghanistan. They had President Amin put to death and installed their own leader, President Babrak Karmal. The War Over the next several years the Soviet Army would battle with the Mujahideen. It was a very difficult battle. Many of the Soviet soldiers were untested in battle and their gear was not designed for the harsh environment of Afghanistan. Also, the Mujahideen soldiers were fighting for their homeland and their religion. They were fierce fighters and had many good places to hide in the mountains. As the war continued with little success, it became a source of embarrassment for the Soviet Union. Their army no longer seemed invincible to the rest of the world. The Soviets also came under increasing international pressure. The war was condemned by the United Nations, the US pulled out of the SALT treaty talks, and the US boycotted the 1980 Olympic Games in Moscow. The War Ends When Mikhail Gorbachev became leader of the Soviet Union he wanted the war to end. He first tried to increase Soviet troops to end the war quickly. However, this didn't work. By 1988 Gorbachev realized the war was costing Soviet troops and hurting their economy. He signed a peace treaty to end the war. The last Soviet troops departed Afghanistan on February 15, 1989. Facts About the Soviet Afghanistan War Because the Soviet Union failed in securing Afghanistan from the rebels for such a long period of time, the war is sometimes referred to as the Soviet Union's Vietnam War. The United States provided the Mujahideen with Stinger missiles. These enabled them to shoot down Soviet helicopters and were a major turning point in the war. Around 13,000 Soviet troops were killed in the war. It's estimated that over 1 million Afghanis died from the war. Most of these were civilians, not soldiers. Around 5 million people fled the country of Afghanistan during the war. Most went to Pakistan or Iraq. The war destroyed much of the country's infrastructure. It became one of the poorest nations in the world after the war was over.

If a president were to declare a “ hands off” policy, what do you think he might be describing
Mamont248 [21]

Answer:

Hands off policy would be described as the policy that means not intervening in matters.

If a president has announced an off hands policy in some matter, that means he has declared that he will not intervene in that matter under any circumstance. He would have nothing to do with it and nobody shall try to have him indulged in that matter.

I hope the answer was helpful.

Thanks for asking.
