1.
Who developed the first ballistic missile?
Correct Answer
C. Werner von Braun
Explanation
Werner von Braun is the correct answer because he was a German engineer and scientist who played a crucial role in the development of the V-2 rocket during World War II. The V-2 rocket was the world's first long-range guided ballistic missile, making von Braun the developer of the first ballistic missile. Robert Goddard, on the other hand, is often referred to as the "father of modern rocketry" but did not develop the first ballistic missile. Joe Bidden and George Brown are not relevant to the development of ballistic missiles.
2.
Which of these is the Russian father of rocketry?
Correct Answer
C. Konstantin Tsiokolvsky
Explanation
Konstantin Tsiokolvsky is considered the Russian father of rocketry because of his pioneering work in the field. He was a Russian scientist and engineer who developed the mathematical theory of rocket propulsion and made significant contributions to the design and development of rocket engines. Tsiokolvsky's work laid the foundation for modern rocketry and space exploration, and his theories continue to be used in the field today.
3.
Who is the first Indian-born woman in space?
Correct Answer
C. Kalpana Chawla
Explanation
Kalpana Chawla is the correct answer because she was the first Indian-born woman to go to space. She was an astronaut and flew on the Space Shuttle Columbia in 1997. Chawla was a role model for many aspiring astronauts and made significant contributions to space exploration.
4.
Who is the first man to land on the moon?
Correct Answer
A. Neil Armstrong
Explanation
Neil Armstrong is the correct answer because he was the first man to land on the moon. On July 20, 1969, Armstrong, along with Buzz Aldrin, became the first astronauts to set foot on the lunar surface during the Apollo 11 mission. Armstrong's famous words, "That's one small step for man, one giant leap for mankind," have become iconic and symbolize this historic achievement in space exploration.
5.
Which of these was not an aerospace engineer?
Correct Answer
D. Graham Bell
Explanation
Graham Bell was not an aerospace engineer. He is widely known as the inventor of the telephone and for his contributions to the field of telecommunications. While Bell made significant advancements in communication technology, he did not specialize in aerospace engineering, which involves the design and development of aircraft and spacecraft. On the other hand, Boback Ferdowski, Neil Armstrong, and Robert Goddard are all notable figures in the field of aerospace engineering, having made significant contributions to space exploration and related technologies.
6.
What country was the first to send a man to space?
Correct Answer
D. Russia
Explanation
Russia was the first country to send a man to space. In 1961, Yuri Gagarin became the first human to orbit the Earth, marking a significant milestone in space exploration. This achievement by the Soviet Union demonstrated their technological prowess and sparked the beginning of the Space Age.
7.
Who is the first man to explore the outer space?
Correct Answer
C. Yuri Gagarin
Explanation
Yuri Gagarin is the correct answer because he was the first man to explore outer space. On April 12, 1961, Gagarin, a Soviet astronaut, successfully completed a single orbit around the Earth aboard the Vostok 1 spacecraft. This historic achievement made him the first human being to venture into space, marking a significant milestone in space exploration and paving the way for future missions. Neil Armstrong, on the other hand, was the first man to walk on the moon, not the first to explore outer space. Thomas Walters and Robert Goddard are not known for their contributions to space exploration.
8.
Which of these objects is most developed to obey the laws of aerodynamics?
Correct Answer
C. Rocket
Explanation
The rocket is the most developed object to obey the laws of aerodynamics because it is specifically designed to travel through the atmosphere and outer space. Rockets are built with streamlined shapes and aerodynamic features to minimize air resistance and maximize efficiency during flight. They have powerful engines that generate thrust to overcome gravity and propel them forward. Rockets also have fins and stabilizers to maintain stability and control their trajectory. Overall, rockets undergo extensive engineering and testing to ensure they can withstand the forces of aerodynamics and achieve successful space missions.
9.
Which of these is concerned with the electronics of aerodynamic structures?
Correct Answer
B. Avionics
Explanation
Avionics is concerned with the electronics of aerodynamic structures. It involves the development and implementation of electronic systems in aircraft, such as communication systems, navigation systems, and flight control systems. Avionics plays a crucial role in ensuring the safe and efficient operation of aircraft by integrating various electronic components and systems to enhance communication, navigation, and overall aircraft performance.
10.
Which of these share similar laws with aerodynamics?
Correct Answer
A. Fluid mechanics
Explanation
Fluid mechanics is the correct answer because it is the branch of physics that deals with the study of fluids in motion and the forces acting on them. Aerodynamics, on the other hand, is the study of the motion of air and other gases, particularly in relation to the movement of aircraft. Both fluid mechanics and aerodynamics involve the study of the behavior and properties of fluids, making them share similar laws and principles. Mechanics, electrophysiology, and electrotechnology do not specifically focus on the study of fluids and therefore do not share similar laws with aerodynamics.
