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 (1888-1946). It was in his rooms in Soho, London, that in 1925 John Logie Baird made a technical breakthrough: successfully transmitting a 30-line vertically scanned image of the head of a ventriloquist's dummy. A Scottish engineer, Baird is considered to be the inventor of the television.he brilliant Christopher Cockerell came up with one of the greatest British inventions of the second half of the 20th century: the hovercraft.
