The U.S. Navy was established in Philadelphia on October 13, 1775, at the beginning of the American Revolutionary War. The decision to create a naval force was made by the Continental Congress.
Question 3: If you mix all the colors of light together, what color do you get?
When all colors of the visible light spectrum are combined, they create white light. This is because each color contributes a different wavelength, and when they all mix together, the result is the perception of white by the human eye.
Question 4: Who is considered the father of modern Western Philosophy?
René Descartes is famous for his statement, "Cogito, ergo sum," which means "I think, therefore I am." His work in philosophy laid the foundation for modern Western philosophy, especially the development of rationalism.
Question 5: The term "AU" stands for what astronomical measurement?
An Astronomical Unit (AU) is a unit of length used to measure the average distance between the Earth and the Sun, which is approximately 93 million miles (150 million kilometers). It is commonly used to express distances within our solar system.
Question 6: What is the name given to the theoretical boundary around a black hole beyond which nothing can escape, not even light?
The event horizon of a black hole is the point of no return; it's the boundary at which the gravitational pull becomes so great that escape is impossible. The term was popularized in the 1970s, though the concept had been part of black hole theory since the concept's inception.
Question 7: Who was the last pharaoh of ancient Egypt?
Cleopatra VII ruled Egypt from 51 to 30 BC. She was a member of the Ptolemaic dynasty, a family of Greek origin, and served as the last active ruler of the Ptolemaic Kingdom of Egypt. After her death, Egypt became a province of the Roman Empire.
Question 8: What is the name of the famous prison now a museum, located on an island in San Francisco Bay?
Alcatraz was a federal prison from 1934 until 1963, and during its 29 years of operation, it housed notorious criminals like Al Capone and George "Machine Gun" Kelly. It became a national recreation area in 1972 and was opened to the public as a museum.
Question 9: If a car's gas pedal is stuck or malfunctioning, what should the driver do to safely stop the vehicle?
If a car's accelerator pedal sticks, the driver should shift the transmission into neutral. This disengages the engine from the wheels, allowing the car to safely coast to a stop without the engine power. Turning off the ignition while driving can cause loss of power steering and brakes, making the car more difficult to control. The parking brake should only be used at very low speeds to avoid skidding or loss of control.
Question 10: The Earth's outermost layer is called?
The Earth's crust is primarily composed of two types - oceanic crust, which makes up the ocean floors, and continental crust, which forms the continents. The crust is divided into several tectonic plates, which can move and interact, resulting in earthquakes and volcanic activity.
?phone+graph = logical guess
Missed again 
Good guess
maybe I should have said some of the questions and repeated questions!!
%.....long may you reign Your Majesty.
Thomas Edison invented the phonograph with the original intention of recording telephone messages, not music. He thought it could be used in business to record messages that could be played back later. However, it was the ability to record and play back music that ultimately made the phonograph a popular invention.
