Answer 2

The invention of television was the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed, with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass medium for advertising, propaganda, and entertainment.

Robert Hutchings Goddard (October 5, 1882 – August 10, 1945)[1] was an American engineer, professor, physicist, and inventor who is credited with creating and building the world's first liquid-fueled rocket.[2] Goddard successfully launched his rocket on March 16, 1926, ushering in an era of space flight and innovation. He and his team launched 34 rockets[3] between 1926 and 1941, achieving altitudes as high as 2.6 km (1.6 mi) and speeds as fast as 885 km/h (550 mph).
