Answer 2

True or False: Inventions and Discoveries

1) False. Russia was not the first country to send a satellite into space. The first satellite, called Sputnik 1, was launched by the Soviet Union on October 4, 1957 [[1]].

2) False. The television was not invented in the 19th century. The first practical television system was developed in the early 20th century. The first electronic television was demonstrated in 1927 by Philo Farnsworth, an American inventor [[2]].

3) False. Diamonds and coal are not made of the same chemical element. Diamonds are made of carbon, while coal is primarily composed of carbon, along with other elements such as hydrogen, oxygen, and nitrogen [[3]].

4) False. Worms do not have tiny legs that can be seen only under a microscope. Worms move using their muscles and bristles called setae, but they do not have legs [[4]].

5) True. Nuclear energy and atomic energy refer to the same thing. Both terms describe the energy released from the nucleus of an atom through processes like nuclear fission or fusion [[5]].

6) False. Neptune is not the closest planet to the Sun. Mercury is the closest planet to the Sun in our solar system [[6]].

7) False. American astronauts landed on the Moon in 1969, not 1982. The Apollo 11 mission successfully landed astronauts Neil Armstrong and Buzz Aldrin on the Moon on July 20, 1969 [[7]].

8) True. The Earth does have a magnetic field, and invisible lines of magnetic force spread out around the planet, joining the North and South magnetic poles. This magnetic field is what gives rise to phenomena like the auroras and helps protect the Earth from harmful solar radiation [[8]].

9) True. Leopards are known to often hunt from trees, lying in wait on a branch. They are skilled climbers and use trees as vantage points to spot prey and launch surprise attacks [[9]].

10) True. Leonardo da Vinci, the Italian polymath, did think of modern things like the helicopter, the flying machine, and the machine gun. He made detailed drawings and designs of these inventions, although they were not realized during his lifetime [[10]].

11) False. The laser is not a device that strengthens sound. It is a device that emits a focused beam of light through the process of stimulated emission of radiation. Lasers have various applications in fields such as medicine, communications, and industry [[11]].

12) False. The human nervous system includes the brain, nerves, and spinal cord, but not the stomach. The stomach is part of the digestive system, not the nervous system [[12]].

I hope this helps! Let me know if you have any further questions.
