Now, we will learn about Velocity Time Graphs . Velocity-Time Graphs: To draw velocity time graphs, we will use the three equations of motion. Case 1: Velocity-time graphs with constant velocity (zero acceleration) When the velocity is constant, the velocity time graph, with Y-axis denoting velocity and X-axis denoting time, will be like: As clear from the graph, the velocity is constant (c) throughout the time interval.
Nikola Tesla first invented the radar because he knew the America needed help in World War I since German U boats sank hundreds of our boats. Sure it could only detect roughly 6feet out, but it was a start.
John Logie Baird invented and introduced the first TV system in London, England on January 26, 1926. To scan image, Baird used double spiral lenses in this electronic device. The first TV only featured 30 lines, which was one of the reasons why Baird decided to develop an upgraded version.The inventor established a company named Baird Television Development Company. The corporation successfully transmitted a TV signal from London to New York in 1928.he Epsom Derby in 1931 is the first live event that was televised. Baird continued to improve the system until he invented an ultra-short wave electromechanical device in 1932. New models of TV systems created by Baird were launched until 1936.
